The long-awaited return of the GrimmSpeed Bypass Valves is here! Our valves have been a highly sought-after product, but due to the intensive assembly process, it has been hard to keep them on the shelves, which in turn causes frustration among our customers. To address this issue, our team has worked diligently to redesign the BPV to make the assembly process more efficient, while also improving its manufacturability, performance, and overall reliability.

What's New for Version 2?

  • Redesigned the internal piston to eliminate the potential failure points we saw in our V1 design.
  • Adjusted tension of the internal spring to better suit the operating environments we've seen after further testing and development.
  • Updated the design of the main body for a better CNC milling finish.
  • Exchanged the internal brass piston from V1 for a lighter weight hard aluminum piston, resulting in better valve response.
  • Removed the inspection port which was primarily used for quality control, but it is not required with the new design.

In testing of stock bypass valves, we saw repeated internal leakage at boost levels as low as 8psi in the FA20 and 19psi in the EJ variant. As always the case with GrimmSpeed Products, we focus on form AND function, and these units are no exception. We aimed to create an extremely durable bypass valve that could hold double the pressure of the stock unit, while still being a stylish part that compliments the other GrimmSpeed Parts under your hood.
