The heat shield will not perfectly seal up against the hood. So I bought a cheap Swimming Pool Noodle, cut, split and installed it onto the heatshield to help close any gaps under the hood. So now, my filter doesn't suck hardly any hot air from the engine compartment.
Ran into a few fitting issues. Bracket that mounts from fender to heat shield was to short. Had to shim. Holes in intake tube for air flow sensor didn’t line up either and had to get creative. For the money it saved I guess it was worth the trouble.
It's certainly less to worry about! If you don't put too much oil on your oiled filter and let it dry completely though, you should have any issues with sucky residual oil into your engine. -Zach
I would recommend disconnecting your battery during install and letting the truck run for a bit parked after installing so the MAF/computer can adapt to the new air intake. -Zach
I just ordered it and will be installing it on my 2008 Suburban this week. I installed the K&N on my previous 2008, looking at this video so far I see ZERO reason it should have any issues on a 2007-2008. Should know for sure by Thursday night.
