EMPI 8.5mm HEI-style spark plug wire set with matching coil wire — for high-performance, high-energy ignition systems on VW Type 1 air-cooled engines. The thicker 8.5mm wire diameter, upgraded silicone insulation, and HEI-style boots make this the right wire set for engines running MSD, Crane, Pertronix Ignitor II/III, or other high-output electronic ignition systems. EMPI part #00-9442-6.

Why HEI 8.5mm wires for performance ignition

High-energy ignition systems produce significantly hotter spark than stock points or basic electronic ignition modules. That hotter spark needs thicker, better-insulated wires to deliver the energy to the plug without breakdown, crossfire, or radio interference. Stock 7mm Bosch wires are designed for stock-output coils and don't handle high-energy ignition well over time.

8.5mm wires with silicone insulation hold up to the higher voltage, resist heat breakdown, and don't develop the crossfire that's common between adjacent cylinders when wire insulation starts to fail. The HEI-style boots seal tightly around the spark plug and coil tower, eliminating moisture-induced misfires.

Specifications

  • Diameter: 8.5mm (vs. 7mm stock)
  • Style: HEI (High Energy Ignition)
  • Insulation: Silicone
  • Boots: Custom HEI-style spark plug boots, plus matching coil wire boot
  • Sold as: Complete set (4 plug wires + coil wire)
  • Part number: 00-9442-6

Fitment

  • VW Type 1 air-cooled engines running high-output electronic ignition
  • VW Beetle, Karmann Ghia, Type 3, Thing
  • VW Bus / Transporter through 1971 (Type 1 engine)
  • Dune buggies, sand rails, and kit cars with performance ignition setups

Best paired with: MSD ignition boxes, Crane high-energy ignition, Pertronix Ignitor II/III, or any aftermarket coil rated for high secondary voltage. For stock points ignition, standard Bosch wires (#98-9986-B) are correct and these are overkill.

FAQ

Will these work with stock points ignition?
Functionally yes, but you don't need them. Stock points ignition produces moderate spark voltage that standard 7mm Bosch wires handle perfectly. The 8.5mm HEI wires are designed for the higher voltage of performance ignition systems.

Do these reduce radio interference?
The 8.5mm HEI wires include suppression to manage RF interference. They're generally well-behaved with car audio installations, though high-output ignition systems will always produce more RF noise than stock setups.

Will they fit my Type 4 engine?
The fit depends on plug location and distributor cap style. The Type 1 wire set has specific lengths and termination styles for the Type 1 engine layout. For Type 4 (1972+ Bus, 411, 412, Porsche 914), confirm fit before ordering.

Are the boots heat resistant?
Yes. Silicone HEI boots withstand the high temperatures of an air-cooled engine bay far better than rubber boots, which crack and harden over time.

What's the lifespan?
Quality 8.5mm silicone HEI wires typically last 50,000–100,000 miles or 10+ years of moderate use, whichever comes first. Significantly longer than standard 7mm wires under similar conditions.

Do they come with a coil wire?
Yes. The set includes the four spark plug wires plus the coil-to-distributor wire — everything from coil to plug.

Good OEM replacement, but check the contents

This filter was perfect for my 2020 ram 1500, however I had to get a replacement because the gasket was not included in the box as delivered. I contacted the seller and they replaced it within two days. The replacement unit had both the filter, and the gasket in the box it should've been.

Exposing the Roots of Christian Nationalism
Format: eTextbook
Kevin M. Kruse’s One Nation Under God: How Corporate America Invented Christian America dismantles the enduring myth that the United States was founded as a “Christian nation.” Instead, Kruse demonstrates how this identity was deliberately constructed in the mid‑20th century as a political strategy. Beginning in the 1930s, business leaders alarmed by Franklin D. Roosevelt’s New Deal sought to counter what they perceived as government “slavery.” To resist these reforms, they partnered with clergy and promoted the idea of “freedom under God,” blending economic resistance with religious appeal. This alliance reached its zenith during Dwight Eisenhower’s presidency. Eisenhower expanded religion’s role in public life, inaugurating the National Prayer Breakfast, adding “under God” to the Pledge of Allegiance, and making “In God We Trust” the official national motto. These initiatives reshaped American identity, fueling a surge in church membership and embedding religious language into civic rituals. The phrase “one nation under God” became a widely accepted marker of patriotism, crossing political and denominational lines. Kruse’s central argument is that Christian nationalism was not inherited from the Founders but deliberately cultivated by corporate and political interests in the 20th century. By exposing its origins, he reveals how this “invented tradition” continues to shape and divide American politics today. C.S. Lewis, in The Screwtape Letters, anticipated this danger with remarkable clarity. He warned that the gravest temptation is not outright disbelief but the subtle corruption of faith—when Christianity is treated as a means to another end rather than as an end in itself. Lewis’s insight resonates with Kruse’s account: both show how faith can be co‑opted when believers confuse God’s kingdom with Caesar’s. History is important, but it is equally important that we do not allow bad history to repeat—or even to rhyme—when each stanza leads us further from God. Kruse provides the historical scaffolding, Lewis the theological discernment. Together they invite us to vigilance: to name the temptations of Christian nationalism, to resist its allure, and to anchor our communities in the truth that God’s kingdom cannot be co‑opted by worldly power.

Even-handed History of America's Religious Roots
Format: eTextbook
One Nation Under God: How Corporate America Invented Christian America by Kevin Kruse “One Nation Under God" is an even-handed book that makes the record clear on where America’s religious identity came from. Professor Kevin Kruse makes the compelling historical case that America’s religious identity had its roots in the domestic politics against Roosevelt’s New Deal of the 1930s and 1940s. This scholarly 386-page book includes eight chapters broken out into the following three parts: I. Creation, II. Consecration, and III. Conflict. Positives: 1. Interesting and well-written book. Fair and respectful treatment. 2. A fascinating premise, how Corporate America invented a Christian America. 3. Kruse does not waste time in establishing his thesis for the book. “This book argues, the postwar revolution in America’s religious identity had its roots not in the foreign policy panic of the 1950s but rather in the domestic politics of the 1930s and early 1940s.” 4. The origins of the union of Christianity and capitalism. “At First Congregational and elsewhere, the minister reached out warmly to the wealthy, assuring them that their worldly success was a sign of God’s blessings and brushing off the criticism of clergymen who disagreed.” 5. The anti-New Deal movement. “For Fifield and his associates, the phrase “freedom under God”—in contrast with what they saw as oppression under the federal government—became an effective new rallying cry in the early 1950s.” 6. The role that Billy Graham played in American politics. “As the Washington crusade began in January 1952, Graham made clear his intent to influence national politics.” 7. It’s always interesting to read about the fathers of prominent politicians and religious leaders of today or recent past. See how many you find. 8. Political opportunism illustrated. “Vereide recognized that the tensions of the Cold War could be exploited to win more converts to his cause.” 9. A comprehensive look at the history of the National Day of Prayer. “In an apparent nod to the previous year’s “Freedom Under God” observance, which was set to be repeated in 1952, Truman selected the Fourth of July as the date for the first National Day of Prayer.” 10. Eisenhower unlikely role as the spiritual leader of a nation. “Eisenhower’s relationship with the Freedoms Foundation ran back to its founding. In his first meeting with Belding in September 1948, he discovered that the ad man shared his belief that the free enterprise system was in desperate need of defense.” “FOR EISENHOWER, THE “GOVERNMENT UNDER God” theme of the first prayer breakfast became a blueprint for his entire administration.” 11. Key stats that show the influence of religion and politics. “The decade and a half after the Second World War, however, saw a significant surge: the percentage claiming a church membership climbed to 57 percent in 1950 and then spiked to an all-time high of 69 percent at the end of the decade.” 12. The drive to declare the United States as one based on the Bible. In God We Trust. “In July 1953, the National Association of Evangelicals arranged to have Eisenhower, Nixon, and other high-ranking officials sign a statement declaring that the United States government was based on biblical principles.” 13. Interesting tidbits about our founding fathers. “The founding fathers had felt no need to acknowledge “the law and authority of Jesus Christ,” and neither had subsequent generations of American legislators.” 14. A comprehensive look at the history of the Pledge of Allegiance. “THE ORIGINAL PLEDGE OF ALLEGIANCE, much like the Constitution itself, did not acknowledge the existence of God. Its author, Francis Bellamy, a Baptist minister from Rome, New York, was a decidedly religious man, but when he wrote the pledge in the 1890s he described himself as something that would seem an oxymoron in Eisenhower’s America: a ‘Christian socialist’.” 15. Interesting history on the need to create an illusion of historical accuracy. 16. Separation of church and state. “The justice reached back to borrow a metaphor coined in a letter to his fellow Baptists in Danbury, Connecticut, two and a half centuries before. “In the words of Jefferson,” Black wrote, “the clause against establishment of religion by laws was intended to erect ‘a wall of separation between church and state.” “Religious liberty was essential, he told his wife, because “when one religion gets predominance, they immediately try to suppress the others.” 17. A look at the quest for school prayer amendment. The tactics used by both sides. “The issue is that agencies of government cannot avoid favoring one denomination and hurting another by the practical decisions that have to be made by government authority on what version of the Bible shall be imposed and what prayer. The churches know this and that is why they are against the Becker Amendment.” 18. Prayers at the White House. “In creating a “kind of sanctuary” in the East Room, Nixon committed the very sin the founders had sought to avoid.” 19. Republicans use of religion for political gain. “Much as Reagan used school prayer as a partisan issue, Bush used the pledge.” 20. An excellent epilogue. 21. Notes included. A section of abbreviations. Negatives: 1. Interesting but on the dry side. The book is scholarly but the author lacks flare. 2. Lacks conviction. The book feels more like a cold report than an engaging thesis. 3. Charts and timelines would have added value. 4. No formal bibliography. 5. At $14.92 for a Kindle book when the Hardcover was available for $15.70 at time of purchase may hurt some trees. In summary, this is really a 3.5 star book but I’m feeling generous. On the one hand, it’s an interesting topic that is covered in a fair and respectful manner while on the other hand it lacks panache. Kruse provides great insights into the evolution of the religious right and makes a compelling case of their true origins. A worthwhile book to read, I recommend it! Further recommendations: “Why the Religious Right Is Wrong about Separation of Church and State” by Robert Boston, “Nonbeliever Nation” by David Niose, “The Dark Side of Christian History” by Helen Ellerbe, “Birth Control, Insurance Coverage, & the Religious Right” by A.F. Alexander, “The God Argument” by A.C. Grayling, “Freethinkers” by Susan Jacoby, “Moral Combat” by Sikivu Hutchinson, “Republican Gomorrah” by Max Blumenthal, “American Fascists” by Chris Hedges, “Doubt” by Jennifer Michael Hecht, and “Society Without God” by Phil Zuckerman.
