The Full-Race 3-Port MAC Boost Control Solenoid (BCS) is engineered as a top electronic boost control device for modern turbocharged applications, providing the ultimate in precise and repeatable boost control. Designed for consistent performance and extended service life, the 3-Port BCS adds the flexibility and precision necessary for properly controlling boost via the factory ECU or a standalone engine management system. It is often required when upgrading to larger turbos or external wastegates to manage increased performance and improve tunability.
Features
- Provides accurate and consistent boost control, eliminating boost fluctuations.
- Rated to operate up to 120 psi.
- Features a patented high-force MACSOLENOID for the fastest possible response times and extremely high cycle rate capability.
- Constructed with Viton spools and seals throughout for long life.
- Includes a waterproof design with a sealed O-ring manual override and a waterproof grommet on the wiring harness.
- Has a manual override feature that reverts the turbo to wastegate spring pressure upon failure, acting as a safety against overboost.
Notes
- If upgrading from a 2-port solenoid, the boost control tables will need to be re-tuned to operate properly in 3-port mode.
- Upgrading to a 3-port solenoid will require lower boost control solenoid duty cycle settings to avoid overboost.
Compatibility Notes
- Ideal for use in sealed dual port internal wastegate applications, both internal and external.
- Compatible with Hondata S300, K-Pro, Flashpro, Cobb Tuning AccessPort, SCT, Haltech, Holly EFI, and many more.
- Supports all PWM modulated standalone and piggyback ECUs.

Really Helps-Especially for Star Station Tests-Haven’t Failed Since Using in Two Older Vehicles
Size: 1 Count (Pack of 1)
Ever since the new CA State mandate that older cars and trucks have to go to a Star Emissions Station for their smog check I have become very familiar with Guaranteed to Pass. The first year of getting smogged under the new regulations my 1995 truck barely failed. It’s a tougher series of tests and it really sucks to have to pay more for a smog test that is designed to get older cars and trucks off the road that would normally pass a regular smog check. It came at a bad time, having just been laid off and losing my health insurance and income and trying to figure how to come up with money for truck repairs to get my registration renewed so I could be a viable job candidate in the really bad job market of a few years back (and still today, may I add.) But that is a whole other issue that gets my blood boiling. So back to my experience with Guaranteed to Pass. My 1995 Ford Truck barely failed and I mean barely according to the emission numbers so I had the manifold cleaned out, used premium gas for a tank and added Guaranteed to Pass. Having two gas tanks was handy as I could switch the tank to a fresh tank without the remainder of the additive in it for the retest. It passed with flying colors.
So for our other older 1993 mini-van and the truck in the few successive years since I always run the premium gas with Guaranteed to Pass in the tanks before the smog check. We’ve had the van and truck tested 3-4 times combined since and they pass every time. So I’m sold on Guaranteed to Pass and will vouch for it.

No more struggling on n54 oil filter cap!
Color: Black, Color: Black
First of all, this is a lifesaver. Getting the oil filter cap on the bmw N54 is a pain to tighten. I can not stress it enough. However this oil filter cap is most definitely the best purchase i have ever made during the oil change process. Before i bought it i damaged my oil filter cap because i didn't have the correct wrench and had to use big pliers to tighten it. Im glad i made this purchase, it’s affordable, good quality, super easy to use, grips the cap well, looks nice and clean, and works extremely well overall. This makes my life owning a N54 powered BMW much more convenient, especially as a DIY’er. I would 100% recommend this product, 5/5 stars.
