air intake system

quick question! which is the best air intake system for the 07 tahoe. I cant make up my mind??? there are so many choices!! please help!! my budget is pretty open? i currently have an flowmaster 50series suv exhaust  muffler which sounds great!!!!!!!!!!

I dont think you can go very wrong in this category as long as you stick to some of the big names. I personally want to get the K&N 63 series (lower on price and K&N says it has the largest gains). But the Volant is good, I have heard good things about the AEM Bruteforce, and the Airraid.

The hp gains for most CAIs occur at the upper rpm band.  Take a look at the Trueflow system.  They have an informative video on their website.

It has been said the GM intake provides the best output througout the RPM range.  However, they are pricey but they look great with the chrome lid.

Im running a TrueFlow XDI. I like it......Did I see any real horsepower gains? Maybe, Maybe Not.....I did however see a difference in the intake temp on my Edge module. The intake temp runs at or near the ambient air temp while driving.  At idle it does increase +/- 5-10 degrees. At about 3500 RPM it sounds like the whistle of the supercharger on my Cobra R but just a little (ok.... a lot) quieter. I opened the system up with about 7500 miles on it to see how the inside on of the tube looked. I must say that there was no film, oil, or dust leading into the intake. Overall I've been quite impressed with the quality and filtration of the Trueflow products.

I have been wondering the same.
 
K&N 63-3050 AIR INTAKE

Save your money for the 6.2L next year in the 4X4, on sale now in 2WD Tahoe.

But ZX, you just know we're going to slap one on that motor as well.

                                

I went with the 63 series from K&N.  It is definitely louder than stock, that's for sure, and it was also easy to install.  I don't regret it one bit. 

I installed the Injen (www.injen.com) system on my truck. Best intake I've ever purchased. And i've used K&N and Volant previously on my Escalade and Super Duty. The polished intake tube looks sick too! I could definitely feel a difference and the motor sounds ALOT better too! I'll try and get some pics

I know, I know.   I just didn't want to tell everyone that when I installed the GM Performance Air Intake Kit on my 07 Tahoe the fuel economy improved 25% and the engine gained almost 60hp. I'm telling you guys I couldn’t believe it myself but its true, that is the only system I will ever buy. Now I just spend my days (and nights) driving around looking for police helicopters to outrun.

Only 60 hp.  Better take it back.
