I'm right there with ya! When I was in my 20's, Hooker Super Comps and Flowmasters on a 350 Small Block with a 280º Cam was the coolest thing since sliced bread. It didn't matter if I could hear the radio. Heck, half the time I didn't even have a radio!

Nowadays I'd much rather just be able to have a conversation while driving in my vehicle and getting 18-20 MPG. Man, I'm getting old.

Ah, the good ole days...

Which is the best I do not know.But I can say I have the K&N on mine and it has been good to me but it was on the truck when I bought it.Apperently it didn't give enough of an increase on fuel economy to the previous owner because he traded it in on a Chevy Cobalt

.I don't know if I would run a K&N in real dusty conditions though.I have had issues with them on my Quad letting dirt through into the carbs even with a pre filter.

Bill, I currently have the stock intake with drop in AEM filter. I don't want to do anything drastic to affect my custom tunes. I've read on some forums that the Gotts intake shouldn't be done on 2004+ models?? What's your opinion? Also, what about the Airaid Jr. Modular Intake Tube? Would the MIT cause enough difference in air flow to cause the need for re-calibration? The MIT is relatively inexpensive compared to the other CAI systems. It looks nice and clean too. Opinions anyone???

Here's something interesting too. I took the intake tube off, and sure enough the snorkel is only 2" wide into the fender. I also noticed 6 small holes drilled into the intake tube near the snorkel. Each Helmholtz resonator had a hole drilled in the bottom as well. I'm guessing this is to assist in airflow at WOT????? I bet this is where the occasional air intake whistle comes from when starting in cold weather. The holes would seem to defeat the purpose of bringing in cold air from the fender. Hmmmmm.......

We've been doing the "Gotts" mod on the 04+ since they came out and have had no adverse effects whatsoever. AFR is not significantly affected.

Mark, I think the holes in the resonators act a bit like "shock absorbers" to dampen out the "springyness" of the air inside. It's possibly like the tuned port in a base reflex speaker enclosure.

As far as the 6 holes in the bottom of the intake, these don't make sense to me at all. We used to see a flapper door in the intake that would pull air off the exhaust manifold during cold weather to aid in cold weather starting and running, but it would close when the engine got warm. These things are always open though. You could be right about them allowing additional air in during WOT at high RPM, but it seems like an odd way to do it. Actually, the Bernoulli effect means that regardless of throttle position, air is ALWAYS being pulled in through these holes and mixed with the air coming from the fender well. Their position is not really over anything "hot" though. I wonder if they are part of the silencer system?

I've never heard the "intake whistle", but we don't get very cold here.

I'm tempted to tape over the holes with aluminum tape to see what happens.

I think you're spot-on there... Instead of amplifying the offending frequencies, it helps dampen them.

I was wondering what kind of experiences Bill or any others have had with the volant cai?

Okay for anyone looking to do an upgrade to their air intake try looking at tru-flo sealed system. It retains stock air box and gets rid of that plastic intake tube, then is replaced with a powder coated tube over to the fender. So you can use any stock filter replacement that you desire or the one it comes with. Just a thought for some of us out there whose parts bins are empty.

And, Lars, it sounds like this does not alter the stock MAF sensor enclosure in any way? I'm puzzled now that it would make your engine run poorly.
