1.4T Upgraded Bypass Valve Spring
This product is currently out of stock.
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.
