K&N Vent Air Filter/ Breather: High Performance, Premium, Washable, Replacement Engine Filter: Filter Height: 1.5 In, Flange Length: 0.875 In, Shape: Breather, 62-1000

This looks like a good quality filter. I'm using on my Harley just as an external oil breather. Not being used for any performance gain.

Works great.i removed recovery canister on mtpy xr650l

Good quality.

Great little filter. Needed it to make a custom air intake for my 2021 Dodge Charger RT. Really high quality materials and it looks great

Great product. Good price.

Got dirty after one ride. As a breather vent, there must be a better way

I wish the details for K&N products on amazon were more about the specific product and not all of their products. This thing seems well built and whoever took the airbox off of my 2013 Triumph Scrambler didn't add a filter to the crankcase breather. The end of that breather that connects to the airbox opens up to about 3/4" but further down the tube it shrinks down to 7/16". There aren't really any adapters to take a hose from 7/16" to 3/8" (since that is the size of the inlet of the filter) so I just tightened down the hose clamp onto this filter and it seems to work alright.

Used it to reroute the vent line for my fuel tank so that dust wouldn't clog up the charcoal canister purge solenoid. No more check engine codes related to that while romping through the desert so it's doing it's job
