The Injen Speed Pro series intake systems for 2008 - 2010 Subaru WRX are a game - changer. They use special tuning technology to boost performance and keep the A/F ratio safe. The Mega Ram system, with its patent - pending tech, restricts the air intake at one spot and then maximizes airflow elsewhere, sending the most air possible to the intake manifold. These Injen SP intakes are custom - tuned for your vehicle, engine, and ECU. Other air intakes may make the engine run too lean, leading to overheating and engine damage. But the Injen SP gives you cold air flow tuned for top performance and engine safety. By cutting down on turbulence and providing a smoother flow through the high - performance filter, it delivers better horsepower and torque than the stock setup. Injen has achieved gains of over 18 HP and 8 ft/lbs of torque! Each intake is made of 6061, T - 6 aluminum alloy and comes with an Injen performance dry air filter with a built - in velocity stack. It also includes stainless steel clamps, high - quality silicone hoses, and instructions.


Using this Injen cold air intake is easy. First, follow the instructions that come with the kit to install it on your 2008 - 2014 Subaru WRX or STI. Make sure all the stainless steel clamps are tightened properly and the silicone hoses are connected well. When it comes to maintenance, check the Injen performance dry air filter regularly. If it looks dirty, you can clean it according to the filter's cleaning guide. As for usage, just drive your car as normal and enjoy the extra power. One important note: don't modify the intake system on your own, as it's specifically tuned for your vehicle. Any changes might affect the performance and engine safety.
