Review on AEM Gun Metal Brute Force Intake System 21-8402DC: Unleash Maximum Performance by Devin Maselli

Assembly: The product itself is very well made and fits perfectly. All the necessary screws and clamps were included with very clear instructions. I wouldn't call myself a mechanic and completed the complete removal of the existing air filter system and installation of a new one in about 1 hour at my usual pace. Gas Economy: I bought this intake for my 2003 6-cylinder Tacoma Pre-Runner in hopes. to earn some gas. Calculating gas savings is difficult, but I would be confident that I would get an extra 10 miles on a full 17 gallons. At a savings of $2.00 per weekly gas station, the induction system will take approximately 2.25 years to pay for itself. Extra Power: Impossible to tell the difference. Noise: I was a little worried about the noise mentioned in other reviews. The noise increases when you stand on it, but not too much. In normal driving it differs slightly from the standard air intake system. Overall: I've looked at several intake systems and settled on this one and I'm glad I did. It fits without any modification, opens up the engine bay, installs easily, maybe gets me a little more horsepower and maybe a few bucks every time I fill up. If you decide to put it in, your truck will live up to your expectations.
