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.

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.

GM Transitioned to Fixed Orifice PCV Systems in LS Engines Around 1999, Initially in Trucks.
Fit in my '03 LQ4. No issues so far and not much to go wrong without an actual valve. General Motors began implementing a PCV (Positive Crankcase Ventilation) system utilizing a fixed orifice, rather than a traditional spring-operated valve, in its LS-based truck engines as early as the 1999 model year. This design was later adopted for passenger car LS engines, notably as a solution to address oil consumption issues in early LS1 engines.

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%
