Maximize your Trailblzers performance with our high performance air intake system. Our intakes surpass our competitors with superior quality and craftsmanship while achieving outstanding performance gains. We see on average, a 14 rwhp increase on an otherwise stock Trailblazer. This is a direct replacement for the OEM air box. No modifications required. • 14 rwhp (NO Tune required!!) Horsepower Gains indicated is to the wheels (whp). CAI Inc. test our systems under real world driving conditions, and dyno test our products to the wheels with the hood closed. Many of our competitors test with the hood open, and under conditions that are not applicable to real world driving. This results in inflated hp numbers that are to the crank, and do not represent real world performance gains. CAI Inc. believes in bringing you the most accurate and applicable information possible, which is why we test the way we do.
