"The entire product went together easily, however the kit should include some torque specifications and warning for attaching the mass air sensor to the inlet--my mass air sensor cracked at two screw holes/attachment points although I only used a screwdriver handle/1/4in drive socket allen wrench! Truck runs great and you can feel the power change immediately." —Richard D from Apo, AE bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2004 Chevy Silverado.
"Super easy to install, it only took me about 10 minutes. There is a very distinctive whistle, I believe my K&N 77 series makes it even louder. I did not notice a big difference in the power, but my fuel efficiency has improved by ~0.5-1 MPG. If you are like me and you want to save a few bucks at the pump, this is a good start." —Steven T from Havelock, NC bought an Airaid PowerAid Throttle Body Spacer for a 2004 Chevy Silverado.
"I have had my K@N for about 2 weeks now, and I love it. It sounds great, gives my motor a little smoother run, and it looks cool too. I am probably getting about 1mpg better with it on. It only took about an hour to put on. So far so good. I have been a K&N guy for years, and they have yet to fail me. I have a 2004 Silverado Z71." —David K from Itasca, IL bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2004 Chevy Silverado.

"It was as easy to install as stated. This is coming from someone who has never installed anything like this before. Everyone who knows me is shocked when I tell them what I did. As far as performance you can feel the extra HP and it sounds great. My first mileage check came in up slightly to 17.5 mpg on my 2004 Silverado.

"The Volant with the scoop is one of the most expensive products of this type the You can buy for Your vehicle. That being said, I would recommend this to all who wants an instant performance increase. Using only My "butt-dyno" I noticed a big difference. My '04 Silverado with the 5.3 is very happy taking BIG gulps of cold air and so am I. Volants customer service leaves some to be desired but the product is the best there is. Autoanything on the other hand has great service and very fast order processing." —Albert M from Santa Ana, CA bought a Volant Cold Air Intakes for a 2004 Chevy Silverado.
