It works perfectly
It works as it should. Fit perfectly in my 2003 chevy silverado. Good price. Easy to install.

Correct PCV valave for a Metered air application
This is a metered PCV valve. meaning there is no actual valve, just a small hole for a "metered" amount of air. This is the correct PCV fitting for an LS application. With a Standard Check valve type I was getting a surging idle. This fixed that problem.

Works Exactly As-Designed
This small simple piece is exactly what you need if you have a vehicle with throttle-body fuel injection, including those with aftermarket units. Unlike a traditional PCV valve, which has a spring and ball/plunger inside, this is a completely hollow fitting. You can see right through it, which is exactly how it was designed. The very small hole meters the precise amount of engine blowby into the vacuum stream, to prevent throttle A/F variations. It's like a precisely controlled vacuum leak. This is how it is designed and how it works, so when you receive it, do not think it's defective. It isn't. Great product...

Fixed orifice PCV perfect with performance cam and Holley Sniper EFI
Just what's needed with the Holley Sniper EFI and a performance camsaft (idle vacuum ~14 or less) which is sensitive to vacuum fluctuations from conventional "valved" PCV.

No es original y no hace su funcion
Es una estafa, una válvula Pcv debe permitir amel flujo de aire a un solo lado, está es solo una manguera o tubo que pasa el aire por ambos lados, está hueco además el empaque es solo una bolsa de plástico, no es original ni sirve, es estafa 100%
