Welcome to Flyin' Miata!

Turbosmart Kompact recirculating bypass valve

3' of 3/4" hose is also included for plumbing purposes
Turbosmart Kompact recirculating bypass valve
Lighter, smaller, better sealing and quieter than others on the market.

Exclusive to Flyin' Miata

Availability: In stock



This little bypass valve is a tiny, lightweight little thing - great for packaging into tight spaces. But it's a quality unit that seals better than anything else we've tried. It's also quieter than most valves. We've tested it at up to 15 psi on a GT3071.
Custom made for Flyin' Miata!

1 3/8" (34mm) inlet and 3/4" (20mm) outlet with all-metal construction. Included in all new Voodoo II and FM II turbo kits and Mazdaspeed complete intake kits. Includes 3 feet of 3/4" hose for hook up. Please note, this is not compatible with a Mazdaspeed Miata using a stock throttle body inlet pipe.

Intended for use as a recirculated valve. We also have a version with a larger 34mm outlet and a filter that is intended for vent to atmosphere (BOV/blow-off valve) use.
