GrimmSpeed Boost Control Solenoid – Hyundai Turbo Models

Available on back-order


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

The GrimmSpeed Hyundai 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 significant increase of power. Planning on returning the car back to stock? Our BCS requires no splicing or soldering of resistors so uninstalling 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
  • The Only Direct Bolt-IN BCS for Velostar Turbo
