MSD Ultra 6AL Plus Ignition Boxes

The new Ultra 6AL Plus ignition boxes deliver full MSD power in a compact, lighter package! The Ultra 6AL Series continues to use a high-speed controller that can make extremely quick compensations to the output voltage, multiple spark series, timing and rpm limits, while maintaining precise timing and accurate rev limiting. The circuits and controller of the MSD have been thoroughly filtered to create protection against Electro Magnetic Interference (EMI). Ultra 6AL Series features a capacitive discharge ignition design. (The majority of stock ignition systems are inductive ignitions, in which the coil must store and step up the voltage to maximum strength in between each firing. At higher RPM, since there's less time to charge the coil to full capacity, the voltage falls short of reaching maximum energywhich results in a loss of power or top end miss.)

MSD Ultra 6AL Plus ignition box details:

* High conversion efficiency ensures minimal heat generation and maximum spark energy output with less current draw from the battery
* High RPM operation and maximum output using the Blaster HVC, PN 8252 or HVC II, PN 8253
* Powerful capacitive discharge of multiple sparks improves performance
* Consistently high spark energy of 135mJ to 150mJ for every firing, from idle to redline RPM
* Increase spark series duration lasts for 18 of crankshaft rotation
* Easily installs on 4, 6, 8-cylinder engines with distributors
* Operates on most 7 to 28 volt electrical systems
* Connects to points, magnetic pickups, and hall/crank input distributors
* Bluetooth connectivity to mobile app interface for settings and monitors
* MSD CAN communication for easy connectivity to MSDView using a CAN MSD Hub and Power Grid USB or CAN-USB Bridge 89982 product
* Straight USB port to easily connect to MSDView using a laptop
* Fully protected against an open coil, shorted coil and open load
* Compact design full MSD power
* Quickens throttle response and improves starting
* Tach Output
* Launch, Burnout, and Step Retard activation inputs available. This ignition box has a built-in tri step RPM rev limit controlled by the mobile app
* Mobile app available settings: Step retard value, Launch RPM value, Burnout RPM value, Max (Race) RPM Value
* Programmable Step Retard: On Ramp time, Off Delay, Off Ramp Time, Engine RPM for activation
* Programmable Start Retard through rotary switches: 0, 10, 20 degrees
* Programmable cylinder selection through rotary switches: 4, 6, and 8 cylinders
* Alerts and monitors available
* High level of security connection from phone to Ignition box (encryption), including sequence in push button implementation
* Maximum programmable retard of 35 degrees
* Programmable timing curves in 2D plots or 3D tables (RPM vs Timing vs MAP Pressure); you can plot the 3-D graph and edit a table 20x20 either from mobile app (phone) or from MSDView (laptop)
* Programmable Launch Timing (seconds vs degrees after launch wire activation)
* MAP sensor interface up to 400 kPA (58 psi / 4 Bars)
* Capable of programming cylinder selection and start retard without a computer or app for old school racers (like 6425 or 6428 box)

Adorable, well-made suit—perfect for special occasions 🤵✨
This suit exceeded my expectations! The color is beautiful and looks even better in person—perfect for weddings, parties, or any formal event. My son looked so sharp and received so many compliments. The fabric feels lightweight and breathable, which is great for warmer weather. It doesn’t feel stiff or uncomfortable, so he was able to move around easily all day. The set comes with everything you need—the jacket, vest, pants, and tie—making it a great value. I also appreciate the adjustable waistband on the pants, which helped get a better fit. Overall, the suit looks very polished and high-quality without the high price tag. Only small note: since it’s linen, it can wrinkle a bit, so you may want to lightly steam it before wearing. Overall, a fantastic outfit for any formal occasion—definitely recommend!

Sharp Linen Suit with a Breathable Fit for Summer
Size: 5, Color: Black
This 3-piece suit is a solid option for a summer wedding or any formal event where you want a kid to look sharp without them overheating. The linen material is high quality and feels much more breathable than a standard polyester suit. The jacket, vest, and pants all fit true to size and the stitching is clean throughout. I was impressed with how well the fabric holds its shape without getting excessively wrinkled after a few hours of wear. It’s a grounded, well-made formal set that balances a professional look with the comfort needed for a child to actually move around in it.

sharp Genetalman look for my Toddler
Size: 4, Color: Light Green, Size: 4, Color: Light Green
I was genuinely impressed with the quality of this 3-piece toddler linen suit. The stitching, structure, and overall tailoring give it a polished, high-end look. It doesn’t feel like a flimsy costume suit at all it actually looks like a properly tailored mini version of an adult formal outfit. The green color is absolutely beautiful in person. It’s rich without being too loud and perfect for summer weddings, beach events, or formal family gatherings. The linen blend gives it that breathable, lightweight feel, which is ideal for warmer weather. Now, sizing was completely my fault. I ordered a 4T for my 2-year-old (clearly wishful thinking 😅), so it runs bigger on him right now. But honestly, I’m not mad about it he’ll grow into it, and when he does, he’s going to look amazing. The slim-fit style gives it that modern, sharp look without being overly tight. It also has a working pockets which i thought was really cute The jacket, vest, and pants together create such a classy appearance. I genuinely can’t wait for the next wedding invitation just so he can wear this. Overall, excellent quality, beautiful color, and great craftsmanship. Easy 5 stars.
