    Great Custom Styling. Brighten up the dreary stock engine bay of your 5.0L V8 Mustang with a SpeedForm Chrome Oil Fill Breather that replaces the ugly stock black and yellow oil fill cap that original came on your Pony from Ford.

    Functional. In addition to adding a nice touch to your Mustangs engine compartment, this Oil Fill Breather cap will allow the engine to breathe better under high rpm conditions, especially if the car has a supercharger or a turbocharger.

    Superior Quality & Finish. Made from copper that is triple chrome plated, this Oil Fill Breather Cap is then hand polished to a brilliant shine to prevent pitting and tarnishing.

    Easy Install. The SpeedForm 5.0L Oil Fill Breather Cap has a nice chrome top and a rubber base that is designed to screw directly into the oil fill tube on the passenger's side valve cover. Go from boring stock to custom WOW in just minutes.

    Application. This SpeedForm Chrome Oil Fill Breather Cap is specifically designed for use on the 1986 to 1995 Mustangs equipped with the 5.0L V8, including the 5.0 LX, GT, and SVT Cobra models.

        Does this screw on or push on?

        • This cap will screw directly into the oil fill tube on the passenger side valve cover.

        Will this work with aftermarket ford racing valve covers? I need it to push into the valve cover itself.

        • Yes, this part is compatible with the Ford performance valve covers.

        Can I use this with a working PCV without causing issues?

        • The SpeedForm Chrome Oil Fill Breather would not allow for a functioning PCV system, as the PCV relies on positive crankcase pressure, which you will use when using a breather. Additionally this will allow unmetered air into the engine, via the PCV, which can cause issues with cars equipped with a MAF Sensor.

        What is the height of this product? I have a strut tower brace on my car and it runs right above the oil fill tube and Im not sure if this will fit under the bar or not?

        • It's not that high. Like an inch and a half from the original crankcase cap.

            NOISEY!!!!

            Didn't see anyone else with a strut tower brace and this on the valve cover, I was able to get it on but when I started my car it would not hold idle. And the noise that was coming from it was not what I expected...like having the air tube off at the throttle body from the MAF meter...disappointed....

            Filler cap

            Looks great, made nice, be carful not to over tighten as the threaded part is only rubber so it can be stripped easily if not being careful.

            Dress-Up Chrome Oil Fill Breather

            Great dress up item. I like the finish of the product, unfortunately I neglected to check the clearance of the oil fill spout on valve cover and the Strut Tower Brace installed on my car. There isn't sufficient clearance to install the Breather. I still would recommend the product. In my case error on not really paying attention and not asking enough questions.

            Fits as it should

            Wanted to dress up the engine a little more so I purchased this breather which is a no effort installation. This breather had been my second choice as I had purchased a KandN breather first. Even though KandN indicates it is a screw in application on the 5.0, 302 it is a lousy one. Drop in is more like it. Save yourself time and effort and purchase one of these right from the get go. Don't expect an increase in power with the installation of one of these, however your engine my breathe a little better.

            Cheap for a nice little engine clean up makes it looks nice under the hood. Don't notice any change but I expected that just thought it would be a nice way to make the engine bay shine super easy install.
