1.4T Upgraded Bypass Valve Spring

Turbo Parts & Kits - 1.4T Upgraded Bypass Valve Spring
Turbo Parts & Kits - 1.4T Upgraded Bypass Valve Spring

One of the best parts of owning a turbo car are the turbo noises, and who doesn’t want more of those? This is the perfect quick upgrade for your 1.4L Sonic or Cruze. Simply swap this upgraded spring in for the stock bypass valve spring and you’re good to go. The upgraded spring will get you more pronounced BPV/BOV noise along with reduced off throttle whistle. Note: this does not provide any performance benefit. 

Fits: LUV/LUH/LUJ stock turbo and ZZP Big Wheel turbos. Cannot guarantee compatibility with competitor's turbos.

Easy piece of mind

Replacement stock spring it seems. Bypass noise is a little bit crisper. But definitely a sturdier spring for piece of mind

Great quality

Other than the BS that is 1.4l BPV location, spring is well designed and works nicely.

Boost bypass valve

Seems pretty good. Didn't make much of a difference but it seemed a bit more well made than the stock one(technically aftermarket, cause I've replaced the whole turbo/exhaust manifold once and the turbo cartridge with a billet one once)

Bypass Valve Spring

works great. On stock turbo makes BVP open quicker and the sound is more pronounced. on ZZPs big wheel it opens quick the sound if a bit weird.
