Valve Cover Breather
This valve cover breather simply replaces your factory twist on oil cap on your valve cover. It is beneficial for cars that do not have a PCV system that can keep up with their engine. This will fix the dreaded dipstick popping up issue. It does this by venting excess crankcase pressure when it builds up. We have been told that people have seen power gains and lower oil temps after installing it. This updated version of our valve cover breather only stands at 2.75" tall so it fits better in tighter spots.
This is a simple one piece design, other vendors breathers make adapters to mate to an aftermarket breather. This one is made based off of the factory oil cap and includes a sealing O ring.
PCM programming required, since it is venting your crankcase and allowing your PCV valve to bypass the MAF.
Note: After installation do not remove valve cover breather by grabbing and twisting the top, we have seen failures because of this. The breather is designed to fit very snug, like an oil cap; the proper method for removal is grabbing the base, or bottom, of the breather and turning from there. If you twist the top you may bend or break the mesh material.
