Features & Product Details

The COBB Tuning XLE Bypass Valve has been designed as a compact and lightweight replacement of your OEM components. When adding modifications that increase boost pressure, as well as horsepower, you can risk having the factory bypass valve leaking boost which can throw off your tune, cause your turbocharger to work harder, among other things.

The COBB XLE will hold higher boost pressures, but also incorporates very fast venting of boost under operation. This is achieved in the lightweight components implemented within the design. Less inertia will allow for a faster response.

Additionally, COBB’s exhaust port and piston face will allow the air to evacuate more quickly, allowing the turbocharger to respond sooner between shifts. 
The XLE Bypass Valve is also completely rebuildable in case there should be an o-ring failure. 

Included with the COBB XLE Bypass Valve are a supplied vacuum line, a vacuum port, a pair of port fittings, and an allen tool to make for a ready installation.

Close fit with process west TMIC (original) 2 years ago
4out of 5stars

Hey so I just got this valve and it is a solid build! Looks great and feels great... it didn't come with any instructions but it's pretty self explanatory.. just note on the original pw TMIC for 08-14 wrx this valve barely fits because of the recirc port.. in fact the valve might be pinching off the return hose a little bit.. and also bolt your valve to the IC before screwing in the vacuum nipple unless you don't want to use a socket wrench to tighten the valve down.. cheers

  • Q: Fitment  Oppithian10 months ago

    I installed this with a process west verticooler on a 2013 wrx, it works great but has been rubbing into my brake fluid reservoir real bad. Any advice on how to remedy this?

      A:  It is recommended to use part number PRW PWTMIC13/LHD to correct the fitment of the Verticooler.
