Welcome to Flyin' Miata!

Turbosmart Kompact vent to atmosphere blowoff valve kit

34mm blow-off valve
Turbosmart Kompact vent to atmosphere blowoff valve kit
Dump that boost!

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.
Custom made for Flyin' Miata!

1 3/8" (34mm) inlet and outlet with all-metal construction. Included in our high boost kits with 3071 and larger turbos. This will also fit older FM turbo systems with steel intercooler piping.

Intended for vent to atmosphere (BOV/blow-off valve) use. This means it should not be used on a car with a MAF. We do have a version designed for recirculated use and stock ECUs.

Awesome product
Awesome sounding bov. Build quality is really good and it has a loud and satisfying dump of air noise whenever I let off the gas.
