Why I picked AEM - Are all air intake systems created equal? I don't know. What I do know is that you’re more likely to get Courtney Hansen’s phone number than get accurate test data from auto accessory manufacturer.  

The two things that I do know about Air Intake Systems. 

1. The worst clean filter is better than the best dirty filter. 

2. I’m lazy. 

This given, if I buy a system with a filter that easy to clean, I’ll have the best system for me.  Hands down, I bought an AEM Air Intake System in April of 07 because I don’t have to oil the filter.  I dunk it in a couple of buckets of water after each run, let it dry and stick it back on.       

Now for the B.S. from the manufacturer:

AEM designed its BRUTE FORCE air intake specifically for the Jeep JK and dyno-tunes each system to produce more torque and horsepower.

Our mechanical engineers emphasize tuning the resonance properties of the inlet pipe to help carry more air to the intake valves. We route our plumbing so that the filter draws air from the safest and coolest location, and provide a steel powder coated heat shield to shroud the filter from engine heat and road dirt. Every BRUTE FORCE intake we make is guaranteed for the life of your vehicle.

Our R&D testing procedures and quality-first manufacturing processes set our intakes apart. But what makes our intakes better is they deliver more torque and horsepower while providing superior filtration and performance using our DRYFLOW synthetic air filter. Combine this with a steel heat shield, reinforced brackets, unmatched looks and a lifetime guarantee, and it's easy to see why BRUTE FORCE Intakes deliver the most "Air Power."
