Revolutionizing the boost solenoid market, GrimmSpeed has created model specific install brackets for a factory fit and finish. Features a plug & play fit to the OEM harness. GrimmSpeed worked with many of the top tuners in the country to ensure that this solenoid works safely with the factory ECU.

Features and Benefits:
- Decrease Spool Time - flows 10% more than the competition!
- Plug and Play into OEM Harness - no splicing wires like other BCS solutions!
- Works Safely with Factory ECU - custom coil to match ECU voltage!
- Nickel Plated Fittings - not the easily breakable plastic fittings!
- 15min Installation - extremely simple with our written and video guides!

The GrimmSpeed EBCS 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.

Why run an Electronic BCS over a Manual Boost Controller?

A MBC allows you to run higher than stock boost levels by preventing the wastegate from opening at its rated pressure. It does a great job at this but if boost is available under the MBC setting it will give you that full boost. So for instance, you set your MBC to 18psi because from 3000-6000rpm thats what you want. But then say you get detonation with 18psi when you are at 7000rpm unless you are below 16psi. With a MBC, you do not have this control so you are forced to run 16psi through the entire rev range. With an electronic boost controller you could run 18psi from 3000-6000 and 16psi at 7000rpm because you can tune the boost map in the ECU which will allow you to run the maximum amount of boost at every given rpm. This gives you more power throughout the range and better control. 

Staying with the OEM fitment theme, our Boost Solenoid uses a OEM style wiring harness so you can simply unplug your OEM solenoid and plug ours in. No more cutting the oem wiring and crimping wires together!

GrimmSpeed uses ultra low-profile hose fittings to keep the unit as small and clean as possible. The hose fittings are nickel plated brass so you don't have to worry about them snapping off like the plastic hose fittings!

The solenoid itself is one of a kind. MAC manufactures pneumatic control products for the largest commercial operations in the world, where every minute of downtime can cost tens of thousands of dollars. GrimmSpeed worked closely with their engineers to design this unique valve, incorporating proprietary features, exclusive to GrimmSpeed, that make this solenoid the toughest on the market. Those features include special seals to protect it from moisture and high temp coils to keep response times at 6 milliseconds or less, even in extreme heat. GrimmSpeed worked with many of the top tuners in the country to ensure that this solenoid works safely with the factory ECU.
