ultimate Audi I5 crankcase breather vent adatper

If you own a high power Audi I5 you probably at some point or another have had issues with large amounts of liquid oil 'sloshing' out of the stock vent port on the side of the block. Frankly, the way Audi designed this is much more of a 'blow hole' than a crankcase breather.

To help address this issue, INA Engineering has come up with a nicely engineered 2 piece crankcase breather 'puck' that replaces the factory tin breather port with provisions for packing with stainless wool to both allow large volumes of air, but critically low volumes of OIL from escaping. sold without fittings. Can be setup for AN flare or a barb fitting depending on how you want to setup the rest of your PCV system. The bottom drain fitting is M14x1.5, the top fitting is threaded for AN12. Finished in clear or black anodized for a lifetime of service. Color subject to current availability. If you have a color preference (clear or black) please leave a note and we will try to accommodate if available.

Note that there is a small difference in opening size between i5 blocks, some motors may require a good 2 part epoxy to seal the unit to the engine.
