After alot of research on the "best" intake system for a NBS Silverado, I finally decided to buy the True Flow intake (www.trueflow.com). I never really liked the design of the AEM, FIPK, AirForce, etc. because of the open filter design. I like to keep my truck clean and I rinse down the engine compartment alot so I'm worried about getting water and debris in the exposed filter. The True Flow uses the stock air box and a foam drop in filter that is suppose to not only flow as well as a K&N drop in, but it traps alot more dirt. The True Flow system also has a 4" steel, unseamed tube going from the the air box to the throttle body. Anyways, installation was a breeze and performance seems better. I entered an onramp at about 30 MPH and nailed it. All I saw behind me was smoke and two posi lines. That never happened before from a 30 MPH roll. I guess it's a good matchup with my Corsa catback. So, if you are looking for a quality intake system, consider a True Flow.

 

thanks for the info. i have seen true flow in the mags but never on a truck.
