What our customers say...

This hose is the dumbest design on the 1Z/AHU engine. My vent tube had not only cracked leaking copious amounts of oil after running the engine but the metal bushings in the bolt holes had somehow found their way into my oil pan to clog my oil pickup! This fit perfectly and stopped the leak. Nice of them to include bolts as well. We'll see how it holds up compared to OEM... my guess is just fine.

Great replacement for a cracked breather on my 1z Tdi
