GrimmSpeed Boost Control Solenoid - Genesis 2.0T



The First and Most COMPLETE Genesis BCS Ever Built, Period.

The GrimmSpeed Hyundai Genesis Boost Control Solenoid is designed to work alongside your factory computer (requires tuning). It will not reduce or compromise the life of your ECU because it is designed to draw the same amount of power as the factory BCS, but with better flow and faster reaction. Installation is as easy as bolting in the included mounting bracket, plugging in the connector, and tuning for faster boost response and increased boost pressure; all resulting in a significat increase of power. Planning on returning the car back to stock? Our BCS requires no splicing or soldering of resistors so unistalling the system is a breeze. 

Quick Specs

  • Achieves Much Quicker Boost Rate -flows 10% more than the competition
  • Plug and Play into OEM Harness -no splicing wires like with other BCS'!
  • Factory Fit for Clean Install
  • Works Safely with Factory Hyundai ECU -built with a custom coil to match ECU voltage
  • Nickel Plated Fittings -not the easily breakable plastic fittings; built to last!
  • Easy to Install and Very Easy to Tune
  • The Only Direct Bolt-IN BCS for Genesis

 Why run an Electronic Boost Control Solenoid 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 of this, but if boost is available under the MBC setting it will give you that full boost. For example, you set your MBC to 18psi because from 3000-6000rpm that's what you want, then at 7000rpm you want to run 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 3000-6000rpm and 16psi at 7000rpm because you can tune the boost map in the ECU to allow you to run the maximum amount of boost at every given rpm. This gives you more power throughout the range and better control.


Revolutionizing the boost solenoid market, we have created model specific install brackets that allow you to directly fit our boost solenoid into your Genesis. No more Zip-tying, we've give you the factory fitment you have been asking for! Staying with the OEM fitment theme, our boost solenoid uses a Hyundai-style wiring harness so you can simply unplug your OEM solenoid and plug ours in. No more cutting and crimping OEM wires together! In addition we have used 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 other plastic hose fittings. MAC Valve designed a completely custom valve for our BCS' that cannot be found anywhere else in the automotive tuning industry. The entire assembly is designed with reliability in mind and is guaranteed to withstand the vibrations and temperatures of your engine bay.
Easy for your shop or tuner to tune! (Rememer, an engine tune is required!)


Designed to work with Hyundai Genesis 2.0T.
