It's a well known fact that cooler, denser air contains more oxygen, and more oxygen in your engine's air intake charge means better combustion and more power. Hot air contains fewer oxygen molecules, and if your engine is fed hot air there will be less oxygen and therefore less power. Yet that's exactly what your engine gets with the factory air intake system! The solution to this problem is to install an Injen RD Series Cold Air Intake System.

Injen starts the power improvement process by positioning an Injen High Performance air filter behind the front bumper. Here, this free-flowing filter can take in the coolest air possible and funnel it through smooth, mandrel-bent 6061 aluminum alloy tubing. Injen designs and repeatedly tests its systems for each application to make sure they're the least restrictive, all the way to the throttle body. So, instead of power-robbing hot air squeezing through a restrictive air filter and intake duct, your engine is taking in huge quantities of cool air surging through free-flowing tubing. The result is increased horsepower and torque, and improved performance you can feel!

The RD system is carefully engineered, with CNC machined brackets and adapters, to ensure an exact fit. Installation can be accomplished with simple hand tools and everything necessary for installation is supplied, including comprehensive instructions. The RD Series Cold Air Intake System is backed by a Limited Lifetime Warranty.

This car is awesome. It took just over a hour to install (in the rain). I had to remove the whole front which didn't take long cause it is just held in by screws and a couple clips. The most difficult part was removing the old air box. Other than that it was a breeze. It looks amazing and sounds great. I notice an increase in throttle respond and a better acceleration at around 3500 to 4000rpm.

My buddy a week before installed a short intake and I didn't really notice a difference. However, I did notice the difference with my Injen intake. First off when reading through the instructions I assumed the installation would take a whole weekend, but when all was said and done it only took collectively 3 hours done by myself. Definitely a big deal who really isn't mechanically inclined. As for the difference, the car makes a great sound when you accelerate and definitely gave the car more pick up.
