k&n or volant intake?

I've always like K&N products. I had an AEM Brute Force last, completely regret that decision. I had a weird harmonic that would drone and kind of shake the whole cab at around 2,200 - 3,000 RPM under a medium to heavy load. I put it on after I had a custom exhaust ran, so I'm sure that had an effect, but the drone and shake only happened after the I installed the intake. Just my $0.02 though.

Most 04-05 5.4s need a custom tune when an after market CAI is added or they will run lean. Also, anytime the aftermarket intake changes the position of the MAF, a custom tune is needed for proper A/F ratio.

Bluejay is 100% correct, I didn't pay attention to these guys when I put the K&N intake on my 05 and it ended up costing me over $750 in plugs and repairs from running too lean. I should have spent the money up front and got an upgraded programmer but didn't and it ended up costing me more int he long run. Just put a quality high flow filter and the GOTTS mod, will do the same thing.

I've had the Volant for 5 years now and couldn't be happier, though I had to get a custom programmer for it because it developed a detonation issue almost immediately and I had to take it back off until I got the programmer in hand, was going to get a programmer for the truck anyway as these trucks ('04 -'08) really need one to "wake" them up anyhow. Couldn't be happier with the decision I had made, and I could still do gotts mod if I wanted since I saved all the old air stuff form putting the Volant on it
