Genuine Mopar P4529880 Chrome Breather Cap

Fit great, Look great, What's not to love?

Fit perfectly on my 89 jeep wrangler!2.5 liter had a little to much crank case pressure, completely solved the problem!!

like it

looks good fits good

Finish is really nice. Fit left a little to be desired. They fit really loose in my Wieand aluminum valve covers. But I did figure out a way to make them fit tight. I installed a rubber O-ring behind metal washer. Now when I twist them in they are nice and snug.

I like product appearance & craftsmanship are second to none . Perfect for my 1972 Duster 340.

Product was ordered to be used in Mopar Performance valve covers. As other reviewers have mentioned, the breather fits too loosely, and wobbles around. I had to bend the tangs upward to get the breather to fit properly. I expect a Mopar breather to fit a Mopar Performance valve cover without being modified.

This is junk. Looks nice but wont snug down on the Mopar Performance big block valve covers. More importantly the "filter inside consists of a loose piece of foam rattling around inside. If you value your engine buy something else. Won't filter a thing.
