🔧 High-Quality Beck Arnley 045-0301 PCV Valve for Optimal Engine Performance Review

When I tried this replacement part for my car's emissions system, I was disappointed with its performance. The part failed to properly regulate my vehicle's crankcase pressure, resulting in reduced engine efficiency and increased emissions. While the price was affordable, the poor quality of this product made it not worth it in the long run.

Fits and looks like OEM. How it behaves, time will tell. I had problems idling and stalling in the cold and did a smoke test. It seems to be the culprit. I uploaded a photo where it is leaking. Instead I take OEM.

FYI, this is for 2001-2002 MDX, maybe 2003. It definitely will NOT fit the 2004 model, although Revain claims it does. Unfortunately I'm out the window to return the item so I'm eating $6. Nothing bad, but annoying. This will likely work fine in an older MDX model, but not in 2004 or newer.
