Do vavle breathers work?

I was wondering if seperate air breathers for valves give it more pep.

Nope

they just look kinda cool.. plus u can get them to match the color accents u have in ur engine bay.. nething that cost about $10 under the hood is normally worthless :grinyes:

It would just not be pumpin the hot crankcase air into the intake. hot air = less power. I did'nt notice any diff when I had some.
