KEEP YOUR INTAKE AIR COOL

The IE FDS front-mount intercooler kit (FMIC) increases horsepower and eliminates heat soak. Get the most out of your tuned or big-turbo Audi 2017+ B9 A4, S4, or Allroad by installing the IE FDS intercooler system. The intercooler kit is complete and drop-in.

FDS (FLOW DISTRIBUTION SYSTEM)

The IE FDS (Flow Distribution System) has proven to distribute charge air uniformly across the inlet end of the core. In contrast to other intercoolers on the market which rely on natural airflow across the core, our FDS technology uses precisely shaped and placed fins cast into the inlet plenum to fully take advantage of the large core volume effectively using the entire core. As a result, the IE FDS intercooler has been proven to reduce IAT (intake air temperatures) more so than competing intercoolers, thus offering the largest power gains possible.

TECHNICAL FEATURES

Increasing horsepower of your B9 is a simple task with several tunes and upgraded turbos available. However, it is important to keep in mind that increasing horsepower will result in heat soak of the stock intercooler and parasitic power loss. The IE front-mount intercooler system was designed to directly replace the factory unit while utilizing a much larger core and our proven FDS (Flow Distribution System) to effectively utilize that larger core. These features allow for much higher cooling efficiency than the factory system, thus reducing intake air temperatures and safely increasing horsepower output. The IE FDS intercooler is also a direct fit, requiring no cutting, modification, or time-wasting hassle during installation. Read below for more in-depth information on each intercooler feature.

ELIMINATE HEAT SOAK

Heat soak occurs when the heat generated exceeds the cooling capacity of the intercooler. The most common symptom is the noticeable loss of power after long term acceleration or several back to back power pulls. By greatly increasing the core size and useable area of the core with FDS technology, we have eliminated the heat soak, keeping the intake air temperatures consistently lower than OEM and competitor intercoolers. (See dyno chart in power charts tab)

PRECISION ENGINEERED

Unlike other intercoolers that are simply put together to fit on the car and offer a larger core, the IE FDS intercooler line receives special treatment from start to finish. Our engineering department uses Computational Fluid Dynamics (CFD) software to optimize the end tanks and FDS system for minimum pressure drop and maximum flow and cooling.

DECREASED PRESSURE DROP

Along with lower intake air temperatures, the large core within the IE intercooler also decreases pressure drop when compared to the factory unit. Simply put, pressure drop is the amount of pressure that is lost as air travels through the intercooler. As airflow boost pressure is raised, pressure drop typically begins to climb. By using a larger core that flows much more freely than the factory core, pressure drop is reduced, decreasing the need for the turbocharger to work harder to produce the required boost levels. This allows the turbocharger to deliver more usable boost pressure to the engine. (See dyno chart in power charts tab)

HIGH-QUALITY CONSTRUCTION, PERFECT FITMENT

Not only does it offer the highest cooling efficiency on the market, the IE FDS intercooler also offers perfect OEM replacement with absolutely minimal modification. It has CNC machined mount points and every IE intercooler allows you to reuse the factory mounting points and installs as if it were a factory piece. You will also find that the IE intercooler receives the same attention to detail and quality as every other IE product, with cast and machined end tanks, precise TIG welding, and a dense bar and plate core. Every intercooler is tested on our in house intercooler testing station before shipping, ensuring that it is ready to install.

COMPLETE KIT

The kit comes complete with one FDS intercooler and all hardware needed for installation.

INSTALLATION

Install for the IE B9 FDS Intercooler will require a standard toolset, a couple of torx bits, and some technical expertise. We recommend reviewing our install guide and install an overview video before attempting the install. Installation Guide can be found HERE.

HORSEPOWER & TORQUE RESULTS

The IE Audi B9 FDS Intercooler increases horsepower & torque by decreasing IAT (intake air temperature) and reducing knock. This makes your car much more predictable and consistent because it will not heat soak rapidly like the OE Intercooler.

 

 

PRESSURE DROP RESULTS

Typically upgrading to a larger intercooler core results in added pressure drop, resulting in power loss. IE's FDS design eliminates this problem and works to deliver more boost to the engine by minimizing pressure drop across the intercooler. On the B9 platform, our FDS Intercooler reduces Pressure drop from 1PSI to .3- a drop of approximately 70% at Stage 1 power levels!

INTAKE AIR TEMPERATURE RESULTS

Our unique IE FDS Intercooler design for the Audi B9 platform consistently results in an IAT drop of approximately 20C-30C average at end of open throttle pulls compared to the factory intercooler.

IE FLOW DISTRIBUTION SYSTEM (FDS) FLOW RESULTS

The highly engineered FDS design unique to IE intercoolers uses a carefully shaped fin system located inside the intercooler end tank to force the path of intake air. This ensures charge air utilizes the full intercooler core more effectively than conventional intercoolers resulting is less pressure drop, lower IAT temps, and more power resulting in the most efficient intercooler design on the market.

Creating games isn’t intimidating thanks to this gem of a book. Easy to read and follow, the knowledgeable author makes learning C# fun and helps readers gain confidence, proving even a novice has what it takes to make a game. In addition, the author provides pop quizzes to ensure readers can measure their new-found knowledge before moving onto a new chapter. This hands-on approach is helpful and prevents readers from missing key components. Since my coursework never addressed connecting to the server and pulling data, I found chapter 13 to be of great interest and help. It was interesting to learn what happens behind the scenes and gave me valuable tools to explore, demonstrating this book is advantageous for both novices and professionals. There’s always something new to learn.

Timely and insightful
Format: Hardcover
As Clay Risen thoughtfully makes clear, the Red Scare of this era had roots in earlier decades, and its effects continue to be felt today. The parallels between those years, which included the HUAC and the Hollywood blacklist, and today provide an important examination of 20th century American history. As he writes in the Preface, "Self-described patriotic organizations proliferated, intent on ridding their communities of Communism; one, the Minute Women, had some four hundred chapters nationwide. Parent-teacher organizations, school boards, civic clubs, and Boy Scout troops all came under scrutiny. Hundreds of books were purged from public and school libraries." Reading about the people and stories of that time, you will recognize them again today. I also very much enjoyed his description of how the idea for this book first came to him--as moments from childhood memories which inspired years of research and analysis, and finally this engaging, thoughtful book!

A well-lively account of a recent and unsavory period of American history, roughly 1946-1955.
Format: Hardcover
Red Scare is a well researched and a very readable account of a significant moment in post-World War II American politics. The author situates the rise of the Red Scare in a right-wing reaction to the New Deal, the labor unions, and any forward progress towards civil rights for black and other non-white Americans. The Red Scare gathers force in the Republican Party following a long frustrating period in which the Democratic Party coalition led by FDR remained in power and reshaped the federal government to counter the Great Depression and then mobilize the nation for total war on multiple fronts in Europe and the Pacific. At the beginning of the Cold War, politicians like the young ambitious Richard Nixon find Red-baiting the Democratic Party opposition leads to electoral success in post-war Congressional races. The Republican Party secures a majority in the Senate and the House following the midterm election of 1950. Risen shows a reactionary movement gathering momentum from the Cold War geopolitics that shattered expectations for the peace and security that Americans had hoped for when the war ended in victory. In the wake of the defeat of the Axis powers, Americans felt threatened by the spread of Communist-backed and Communist-inspired regimes, first in Eastern Europe and then in China, then the Korean peninsula. Although the US and Russia were ideologically distinct, they cooperated during the War to defeat their common enemy, namely Hitler and Nazi Germany. But the conclusion of the war brought a decisive end to that cooperation. Instead, there was a series of confrontations in Greece, a divided Germany, and the Eastern European bloc of nations that the Red Army occupied and kept tightly controlled. Roosevelt’s coalition had embraced progressive and socialist proposals like Social Security and the Wagner Act that protected workers’s right to organize and collective bargaining. The Red Scare marked the beginning of a reactionary response to roll back those policies. Meanwhile, the elaborate security apparatus of the Federal government that was empowered during World War II was re-directed against left-wing groups that FBI Director Hoover targeted as “unAmerican.” There was also justifiable alarm that people like Klaus Fuchs spied for the Soviets and passed them much of the secret sauce in the technology developed at considerable expense around the atomic bomb. Risen’s book plays all the hits from that ignominious period: the House Committee on UnAmerican Activities (HUAC), the Hollywood 10, the Alger Hiss affair, the China Lobby, the Smith Act prosecutions against the American Communist Party leaders, the trial and execution of the Rosenbergs, loyalty oaths and blacklists, the persecution of J. Robert Oppenheimer. They are all here. The book chronicles the rise and fall of Senator Joseph McCarthy, and the colorful personalities around his political career including the attorney Joseph Welch that the Army hired to confront him, the TV personality Edward R. Murrow, and his ruthless and feckless henchman Roy Cohn. He sees McCarthy more as a symptom than a cause. Risen shows how Eisenhower, elected President in 1952 on the Republican ticket, co-opted and ultimately blunted the anti-Communist crusade in favor of a less confrontational, more moderate approach. Eisenhower also had a visceral reaction to personal attacks carried out on the integrity of George Marshall for “losing China,” having served under Marshall during the height of his military career. The book also highlights the Supreme Court’s decisive change of heart, under newly appointed Chief Justice Earl Warren, that reasserted 1st Amendment and 4th Amendment rights against guilty by association prosecutions. In many places of the book, the author empathizes the many continuities between the rabid anti-Communist rhetoric and tactics of the early 50s with the right wing politics of the present day, particularly in the area of Public Education.
