I have the K&N intake and as most of you may know , it sucks in alot of hot underhood air. It uses the factory "fresh air" tubing which is a joke. I found this flex pipe on ebay. I figured in theory it should send cold air to the filter , kinda like your fist out the window. Well it works pretty well. I feel a nice increase after 30 mph. Its definetly noticeable at highway speeds. I plan on getting some mesh for the front opening to keep large debris out. I also noticed that it would be pretty easy to route it to the fog light opening for track days.Take a look at the pics and let me know what you think.

There are solutions that mitigate water issues. One is a sleeve/cover that goes over the filter that doesn't let water in. The other, not sure what it is called, is some sort of bypass type solution. You are worrying a little too much. Yes, hydrolock is a possibility, but is rare and easily mitigated.

There should be no worry about hydrolock due to it not being a sealed system. He is still running his K&N intake. He is just using that tubing instead of the factory tubing.

I think it really needs to be raised up some. Seems like it's hanging really low to the ground. It might get snagged on road debris, a speed bump...anything?

I thought about that after I scraped it coming out of the driveway. i think I will bring it up higher.

I covered the filter with a bag and shot the garden hose up the pipe and none made it through. I think by bringing it up higher I can avoid any water issues. Plus the flow of air goes past the filter , not into it.

Thanks. It all came out easy enough except for two screws behind the battery. I was too lazy to take the battery out.

I removed the metal piece and moved it up a bit. It increased my clearance by about an inch. I should be good now.
