SP63 Valve Cover Breather For Mazda Gen 2

$79.95
Quantity:
SKU:
SP63-VCB-MAZDA

Product Description

The stock positive crankcase ventilation (PCV) system on the MZR is known to be problematic even on bone stock cars. Excessive crankcase pressure has been proven to be the #1 cause of the stock turbo beginning to smoke. On higher horsepower cars pushing 25psi or more, the dipstick will push out in order to relieve this pressure which leaves you with oil splattered all over your engine bay. Most oil catch can kits include a check valve to prevent boost from entering the crankcase but this still leaves the problem of a proper exit for all that remaining pressure.

 

Check out our video under product videos!


This valve cover breather screws directly in place of the stock oil cap and provides plenty of relief for all that excessive crankcase pressure. It has an integrated baffle and check ball which prevents unmetered air from entering the crankcase at idle.

NOTE: Currently this product is only available to cars which utilize the second generation (genpu) valve cover. A solution for the first generation valve cover will be available soon. This product is not meant to cure problems from worn piston rings or un-sealing valves resulting in excessive crankcase pressure. If your vehicle is experiencing excessive blow-by, you will see oil come out of this filter which indicates a problem. Please do a compression/leak-down test prior to installing this product to ensure your motor is healthy.

    When I made serious upgraded to my 2013 speed, I knew that I needed this. It vents so well and really makes my engine look amazing.

    Great cap to help with the crank case pressure and help the oil to essentially "breathe"

    Fit perfectly, and looks amazing! Engine seems to sound quieter as weird as it sounds and it feels like the acceleration is smoother. Went with A BNR S4 so it's not knowing there is the pressure in the crank case! Only thing is I wish the breather came with a clamp to hold it in place better, maybe a black one so it looks nice and sleek.

    Posted by on 18th Nov 2014

    Delivery was super fast and packaged well. On first impressions this piece is excellent quality and a simple way to brighten the bay. I didn't have vent issues before but feel confident I won't in the future as psi increases.

  10. Nice quality 5 Star Review

    This breather is very nicely made. Great addition to the engine bay also.
