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.

To be honest the spring did not create any extra noise or sounds enhancement above what I had already experienced with my stock spring setup, I run a K&N short ram intake and deleted the resonator, which already gave a good noise for the turbo, the new zzp spring didn’t enhance the sound any further than what it already was enhanced to by my setup. No harm no foul though for the price it was worth a shot.

Good mod for the money

This was quite a pain to install but once completed, the bypass is a little more crisp and holds very well. It's worth the $15

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)
