The Speed Pro (SP) series short ram intake systems for the 07-13 Mazdaspeed3 feature special tuning technology for optimal performance gains and a safe A/F ratio. The patent pending technology behind the Mega Ram system constricts the air intake at one point, and then maximizes airflow at other points to supply the maximum amount of air to the turbocharger and intake manifold. Injen SP intakes are also specifically tuned for your Mazdaspeed3 engine and engine control unit. Other air intake systems often force the engine to run too lean, risking overheating and other possible engine damage. With the Injen SP, the ram air flow is tuned for optimal performance and engine safety. By reducing turbulence and providing a less restrictive flow through the high performance filter, each intake system is engineered to provide improved horsepower and torque gains over the stock setup. Each 6061, T-6 aluminum alloy intake is finished off with an Injen performance dry air filter with built-in velocity stack and Injen's new aluminum bolt on filter shield, protecting the intake filter from heat and other debris. The Injen SP series short ram intake for the 07-11 Mazdaspeed 3 includes all clamps, silicone hoses, hardware and instructions for a perfect install. Available in both polished or sparkle black powder coated finish.
