Nissan Xterra AEM Brute Force Intake System - 21-8500

AEM designs its BRUTE FORCE intakes for popular trucks, SUVs and late-model, fuel injected musclecars, and dyno-tunes each system to produce more torque and horsepower for large displacement engines. AEM tests against the competition with the goal to outperform all other offerings.

AEM's mechanical engineers emphasize tuning the resonance properties of the inlet pipe to help carry more air to the intake valves. AEM routes the plumbing so that the filter draws air from the safest and coolest location, and provide a steel powdercoated heat shield to shroud the filter from engine heat and road dirt. Every BRUTE FORCE intake we make is guaranteed for life.

AEM's R&D testing procedures and quality-first manufacturing processes set these intakes apart. But what makes AEM's intakes better is that they make more torque and horsepower and deliver superior filtration and performance available through AEM's 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."
