Kompact Dual Port BOV

Dual outlet-type BOV. The Kompact Dual Port vents both to the atmosphere and back into the air intake. Ports with sequential timing allow quieter operation during normal driving, while still offering the performance and sound of a vent-to-atmosphere BOV when the going gets harder.

The standard blow-off valves on these cars are made of plastic, unlike the highly durable machined billet construction of the Kompact. The standard valves are often not up to the task of eliminating damaging compressor surge, and as the cars age, the plastic becomes brittle and can crack, causing severe boost leaks. This prevents the turbo from reaching its full potential, robbing you of performance.

Love it

I bought this for my gen 2 speed3 and I love it. After 30k miles of using it still no shaft play and super responsive. It may just be the kompact one but compared to the regular more expensive one, this one stands the same.

I actually like the Turbosmart more

Hi all, I bought this Hybrid valve for my 2013 Speed 3 as I had it on my 2007 Speed 3 and loved it. Oddly enough, I actually preferred the TurboXS that I had switched out from more.

To me the sound on this one was a bit more of a gush than a whoosh.

Build quality is better than the TurboXS but my car didn't agree with it for some reason.

As always buying from MAP is a dream.
