Max Gains of 15 HP & 34 Ft-lbs of Torque @ 2500 RPM!

For maximum horsepower and torque gains, choose an aFe STAGE 2 Cold Air Intake System. Huge, high-flow conical air filters in three different filter media are the first step to increased airflow to the engine. These intake systems replace the entire air box and intake tract and give the largest performance gains of any aFe intake system. Powder-coated steel heat shields or durable molded plastic air boxes keep hot air out and keep fresh, cool air flowing to the filter.

The improvement in air flow and air temperature of the Stage 2 intake leads to average horsepower gains of 20-40 horsepower and 35-60 lbs. x ft. of torque! The sound is nice and throaty and a definite improvement in engine noise. You’ll love the mean growl the open element provides.
