Grimmspeed Electronic Boost Control Solenoid (Mazdaspeed 3/6)
Get into Boost Much Quicker
(Flows 10% more than competition)
Plug and Play into OEM Harness
(no splicing wire like other BCS!)
Factory Fit for clean install
- Works Safely with Factory Mazda ECU
(custom coil to match ECU)
- Nickel Plated Fittings as this is Built To Last
(not the easily breakable plastic fittings!)
Easy to Install and Very Easy to Tune
- The Only Direct Bolt-IN BCS for MS3
The GrimmSpeed BCS is designed to work with your factory computer (requires tuning). It will not reduce the life of your factory computer because it is designed to draw the same ammount of power as the factory BCS but flows better and reacts faster. It plugs in and requires no splicing or soldering of resistors. With the included bracket you can bolt it in, plug in the connector, and start tuning for fast boost response, increased boost pressure and free up lots of power. Planning on returning the car to stock? Just reverse installation.
- Users can use AN fittings with the solenoid.
- MAC Valve has completely custom made the valve for us(only MAC valve on the market to be custom made for automotive tuning use).
- Specifically designed by GrimmSpeed to work safely with the factory Mazda ECU (requires tuning) and to reliably handle the vibrations and temperatures of your engine bay!
- Direct bolt in mounting bracket and hardware included!
- Faster response and greater flow than any other valve out there. (by more than 10%!)
- Nickel plated brass fittings. (unlike the competitors failure prone plastic fittings)
Bought about a month ago and was everything the description said it was, works great and came fast.
After installing a Garrett GT2871R in my Speed6 I needed something more capable of handling boost control, this item fit perfectly and was extremely easy to install. Great looking product and performs well.
