Made exclusively at Cobra Valley, our hand crafted heavy solid billet T-6 aluminum engine valve cover breathers get the job done cleanly, and with class. Made from the highest quality T-6 billet aluminum and machined to exacting tolerances for a professional appearance and high performance operation.

The hidden vents on the open breather are discreetly positioned underneath, while being vented through baffled holes and filtered to virtually eliminate oil from escaping onto the valve cover, while the PCV version hides the PCV valve inside the breather for a clean, trim look. Various options will deliver the perfect breather for you!

BREATHER GROMMETS for 1-1/4" I.D. valve cover hole w/ 1" O.D. breather neck

Sometimes
breathers fit
looser in the
valve cover than
desired. We have

developed a super tight fitting
grommet where  a coat of oil is
required to slip the tight fitting
breather into the valve cover
grommet. This allows for limited
movement under even hot and
high vibration conditions,
especially with PCV hose fitted
breathers. The baffled grommets
are for covers without oil baffles

The unique look of Stainless Steel aircraft lines accenting an engine is timeless, and with our Aircraft Breathers, you can add a one of a kind look to complete the statement you're making under your hood. Choose our Aircraft breather and incorporate a much needed PCV system into your engines operation. PCV systems create more power through increased crankcase vacuum on the bottom side of the rings, as well as vacuum out all the harmful acidic and gaseous fumes which will make your oil and engine last longer. PCV's also reduce most of the engine oil leaks by keeping a positive seal on all the internal gaskets.

The Aluminum Aircraft fitting on the "Aircraft Breather" model is not just simply 'screwed' into the breather, but rather painstakingly hand fitted to match every curve and contour of the irregularly shaped breather for a truly unique and custom show quality appearance.

The hidden PCV (arrow) on the closed breather is discreetly installed from the bottom of the breather inside the billet aluminum housing, and is vented through the side, appearing as if it was a normal breather

The hidden vents (arrow) on the open breather are discreetly positioned underneath, while being vented through internal baffled holes (arrow) and foam filtered to virtually eliminate oil from escaping onto the valve cover.

You can use a remote breather tank instead of an open breather, select the PCV model, remove the internal PCV and route the hose to a remote location, where if any oil mist does escape, it will be far away from the engine reducing smoke & potential fires.
