RallySport Direct proudly carries a great selection of quality performance upgrades by our friends over at GrimmSpeed.

 

This is the GrimSpeed Electronic Boost Control Solenoid. This is one of GrimmSpeed's most utilized upgrades due to the durability, simplicity of use, and the performance it delivers. This is a must-have for those of you who are getting your vehicle fine-tuned outside of the capacities of the factory 2-port boost control unit. The 3-port system works by interrupting the boost signal that travels from the turbocharger to the wastegate. The factory system will 'bleed' the signal between the turbocharger and the wastegate which will create a system that reacts slowly, and with less precision. The GrimmSpeed BCS will provide a much tighter boost control and consistency that makes life easier for the tuner as the boost control will be more prompt and precise. 

 

DETAILS:

  • Includes 1/4" barbed fittings to match the factory turbo and wastegate hose size
  • The proprietary internal modification design prepares the solenoid for extreme conditions below the vehicle
  • Plug and play operation directly into the factory wiring harness with no modification required
  • Flexible design for aftermarket turbo inlets
  • Provides a quicker, and more precise boost control response
  • Makes tuning more simple and direct for the tuner
  • Includes the 3-port boost control solenoid
  • Includes the plug and play connector
  • Includes a laser cut and CNC bent steel bracket that is zinc plated with stainless press-in nuts
  • Includes zinc-plated barb fittings that are preassembled with anaerobic sealant
  • Includes 4-feet of 1/4" hose and zip ties
  • Includes all of the rest of the necessary hardware for the installation

 

NOTE:

  • This product is not for use with the stock 2015 WRX turbo or other stock replacement turbochargers
  • This solenoid is for aftermarket turbo kits and as such, does not include the required adapter for the stock FA20 turbo inlet
WHY WE CARRY THIS

We only list parts we’d run ourselves or recommend to a friend building a real car. If it feels vague, unverified, or inconsistent, it doesn’t make the cut.

  • Fitment-first mindset — no “universal” roulette
  • Brand reputation matters — we favor proven manufacturing
  • Support that actually responds with real answers
WHAT TO EXPECT

This is the clean path: correct fitment, clean install, and results that match the intent.

  • Install-ready experience with correct mounting where provided
  • Finish that holds up to real driving, not just photos
  • Selections on this page drive the exact fitment shipped

TRUST, BUILT INTO THE PROCESS.

Anyone can list parts. We curate what belongs on a serious build. Our goal is simple: fewer surprises, cleaner installs, and confidence when you hit “Buy.”

Fitment checked

We prioritize vehicle-specific listings and clear selection logic so you’re not gambling on compatibility.

Brand discipline

Proven manufacturing and consistent quality matter more than hype. We bias toward what actually holds up.

Real support

If you have a question, you’ll get a human answer that helps you finish the build — not a copy-paste shrug.
