- Free up Horsepower - Eliminate Crankcase Pressure - Reduce Crankcase Engine Temperatures -

This is a great fix for all the Audi Porsche and VW engines that have oil consumption
problems with the VAG Oil Filler Neck by reducing crankcase pressure from being forced
through the PCV System with Excessive normal engine blow-by. 

Brand new UPR Billet One-Way Crankcase Breather Kit. This is a direct replacement for VAG
style factory oil fill caps. Giving your engine the ability to release unwanted crankcase 
pressure improving overall performance and reliability. Incorporating a High-Performance 
check ball keeping with a spring to eliminate flutter other units suffer from.

This unit releases positive crankcase pressure without allowing any un-metered air to enter
the engine and effect drive-ability. We have gone above and beyond to make sure the fit, 
finish, and performance is what you'd expect from such a performance upgrade. The spring 
forces the unit to remain sealed when not in use and eliminate oil smell in your garage. 

The main benefit is that it drives just like stock until you get into BOOST and it releases 
unwanted crankcase pressure beneath the pistons during the down-stroke. We have also
found these units lower crankcase engine air temperatures as it Triples the amount of fresh 
air through the crankcase improving overall performance and drive-ability.

Incorporating internal baffles to control oil and a tuned spring to keep the unit sealed
and eliminate oil smells when parked in you garage or driveway. Ideal for all street and 
race applications to handle engine blow-by and any boost levels.

Fits the following vehicles:  

AUDI
MK7 GTI, GOLF R
PORSCHE

WILL NOT FIT TDI VEHICLES, OR B8 2.0


KEEP IN MIND ON CARS THAT WITH A LOT OF CRANKCASE PRESSURE BEING VENTED CAN OVERWHELM BAFFLES, AND FILTER YOU MAY HAVE TO REMOVE AND CLEAN THE FILTER, AND BREATHER PERIODICALLY TO REDUCE OIL MIST IF AND WHEN THE FILTER GETS SATURATED.


* ABSOLUTELY NO RETURNS ON INSTALLED PARTS


Maintenance - The filter will need to be checked daily to avoid oil saturation 
from blow-by and to keep the engine bay clean. This is exactly how the 
system should to be maintained for the best level of performance.
