AEM designs its BRUTE FORCE intakes for popular trucks, SUVs and late-model, fuel injected muscle cars, and dyno-tunes each system to create more torque and horsepower than any other intake for large displacement engines. We test against the competition, and won’t release a system unless it outperforms all other offerings.

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 50-state legal or pending legality (excluding “Off Road” systems), and we guarantee them for life.

Our R&D testing procedures and quality-first manufacturing processes set our intakes apart. But what makes our intakes better than the competition is that we make more torque and horsepower and deliver the best filtration and performance available through our DRYFLOW Synthetic filter. Combine this with compete hardware in every kit, 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.”
