I am also thinking about installing a True Flow air intake system. It is a toss up between that and the K&N FIPK Gen II intake system. I have read reviews about both of them, and they see about the same. Only difference is that the True Flow system maintains the factory air box, which is a plus. The True Flow was in Auto magazine with an article on JB Gibbs Tahoe. It is also at www.jbgibbsperformance.com. If anyone has any input on either one of them, let me know please. I plan to make a purchase shortly after Christmas, in which I will begin to post threads about whichever one I buy.

Right now, it's all about the gas mileage. Thanks.
