Any change to your stock intake is an improvement, I have read and dealt with this argument forever.  your Paper filter is designed to be restrictive in order to trap dirt. I read some where that the oil type cone filters are not good for the Hummer because the oil contaminates the sensors, i.e. MAF. The GM performance on is an AEM dry filter. The Resonator Box serves as two functions, one to reduce throttle/accelration noise and stores/maintains a volume off air to prevent that "Punch it" lag you might feel when you change out the box for the direct tube route.  S&B filter sight has a cool CFM calculator, it tell you the cfm flow per your Cu in to rpm rate so you can tune to the right size filter so you don't restrict your engine.  As far as TB Spacers, the only one that I think is worth anything is from Hamburger Performance. And the final thought is It is all about what YOU want.

Oil is only a problem if you over apply it to the filter.  If done properly it will never affect your MAF.

My MAF is clean as a whistle!     Gunny has a point, there has been many a knuckhead to over oil their filter after cleaning and crud up the MAF.  Really though, if you follow the K&N recharger pack (cleaning kit) instructions, and use common sense, my kids could do it.

There is also another purpose to the resonator box.  It is to warm the intake charge in conditions of extreme cold, such as continuous near zero F and below.  GM built these things for service anywhere their off road capacity may be called upon for use.  I leave mine on for the worst of the MI winter weather, although I acknowledge that it hardly could be called conditions of extreme cold.

Hello Gents,

Are air intakes worth it on these vehicles or would a drop-in K&N filter do just fine? Any help would be greatly appreciated!

I see you have a SVT Cobra, have you modified it with an intake? If you did, could you tell the difference? If you did it should have answered your question. Whether you have a Honda Rice Burner or 440 Hemi more air more = power to a point. You have to consider this vehicle and its purpose. It weighs a bunch so the I5 is stressed, Low gearing, but GM put a hefty Tranny in it. But the biggest question is again "What do you Like and want this Vehicle to do" then it doesn't matter, You like it....

Hello, Yes I have a Cobra but it's a totally different animal when you're dealing with a supercharged vehicle vice a normal aspirated motor. When I swapped the intake on my Cobra it netted 37rwhp on the dyno. The exhaust mufflers were also very restrictive from the factory. A CAI and Catback on a 03-04 Cobra was good for 50-60rwhp all day long on the stock supercharger boost level (8.5 psi).

Can I just open up the air box on my 08 just to let the engine breath better?  Has anyone done this without going to an aftermarket filter set-up?

Not a good idea.  Engine compartment air is hot, less dense and less oxygen

Has anyone got any hard evidence about the effects of a modified air intake? Something like a dyno test.
