Pettit Racing Blow Off Valve Upgrade Kit RX-7 FD

The Pettit Racing Blow Off Valve Upgrade Kit is one of our top selling upgrades for the twin turbo RX-7 FD. 

The 1" ports are twice the size of the stock valve which it's a direct bolt-on replacement, and installs in under 30 minutes.

Most original plastic valves are really old and typically no longer work properly, over time heat cycles and normal use cause the diaphragm to harden, which impairs both valve operation and response time. 

Our upgraded BOV is completely CNC machined from billet aluminum, utilizing dual o-rings to seal the piston (no diaphragm to fail like the stock part). Finished in black anodizing. Lifetime Warranty.

Benefits include:

• Better surge protection
• Reduced thrust loading
• Improves boost response time
• Keeps your turbos spooled between shifts
• Provides 50% or more flow than OEM

To take full advantage of this BOV upgrade, Pettit Racing has developed a Hi-Flow Y-Pipe with a 1-in. dump port which connects directly to the new blow off valve.
