Does anyone know where I could find an egine oil breather cap ( chrome with a filter built into the cap) that screws into the spot where the OEM oil filler cap goes. I really like how they look but have had a hard time finding the right one for the 2007 Mustang v6. Most of the ones I can find push in and do not fit very well. I would like a cap that twists on just like the OEM. I tried a generic one and the metal ears looked to be scratching the housing inside and did not fit very well.

Something like this:


Thanks!!

does it do anything functional? or is it just for looks?

 

I have heard mixed reviews. Some say it will cause your engine to breathe better thus increasing throttle response at high rpm's, others say it is a waste of money. I personnaly like the look and if I get a little better performance from the mod, then great!!

its not legal to have that on new cars. It wont do anything to help performace either.

 

You don't need it. The engines emissions system will not work right and the "check engine " light might come on. Leave it alone.

 

That is an "old school" mod....not the same for the newer cars. These cars need to keep the vacuum pressure....

 

Thanks guys, I guess I will have to try to fab something that has the look but retainsthe vacuum. I did not care about function anyway, I just wanted the look. Not worth engine troubles though...

Again thanks to you all.
