This billet aluminum adapter converts the stock VW/Audi 20V valve cover breather outlet to an AN10 male flare. Perfect for upgrading your PCV setup or routing crankcase vapor to an oil catch can.
Machined from 6082 aluminum and finished in silver, it replaces fragile factory plastic fittings with something far more secure—and motorsport worthy. When boosting or running high RPMs, this is a no-brainer upgrade.
Fitment: VW/Audi 1.8T 20V and other 20V engines using the same breather outlet design.
