I've been doing some flow testing, comparing the KN, Fram Air Hog and stock Nissan filters. In all tests, the Air Hog, surprisingly, won out. It flowed with the least pressure drop. It is cotton gauze, like the KN, but is deeper allowing for less drop, and hopefully better filtration than the KN. It also fits in the airbox better than the KN. The differences between all 3 filters are not huge, but they are there, just the same.

I'm waiting for my Volant still, and then will complete my testing and post results.

You'll notice a bigger difference with these performance filters if you do the airbox mod. BTW, all my tests were done with the airbox mod and a modded exhaust, so results may be slightly different on a stock truck. Also, I only measured pressure drop across the filter, not the entire intake.

Stay tuned....

Edit: I've decided not to do oil analysis after running each of these 3 air filters to determine which provides best filtration, as previously mentioned. Reason is, JetTech has done oil analysis after running the Volant and has received excellent lab results. This was while running Mob1 0W-40 oil with a 5,000 mi interval.....not bad, and def good enough for me. I'll also be running the Volant and I'm using Mob1 5W-30, so should have similar results.
