RD Series Cold Air Intake System by Injen®. The RD Series is made for the enthusiast who wants improved mid-range power. This cold air system positions a high-flow air filter behind the bumper, where it can take in cooler, denser air. The cool air then flows to the engine through a fee-flowing aluminum alloy intake tube. Cooler air contains more oxygen for more complete combustion and more horsepower.

Features:

  • Delivers more oxygen to the combustion chamber by drawing in cooler air
  • Custom designed and engineered to deliver maximum power for each specific vehicle
  • Improves acceleration and fuel economy
  • Every system includes the Injen EA Nanofiber dry air filter
  • Air intake pipe constructed of mandrel-bent 6061 aluminum for smooth airflow
  • Most systems are one-piece, however some are two-piece designs
  • Comes complete with all necessary mounting hardware and comprehensive installation instructions
  • Backed by a Limited Lifetime Warranty
  • Proudly manufactured in the USA

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.

Feels like its quality material that is very durable. Easy to install in seconds. Elastic that stretches right over filter. Hard to determine if it really is water resistant b/c I haven't got any water on it that I have noticed. Good investment if you want to keep your filter clean from dirt. Would be nice if it came for free when you purchase the intake.

Sure looks better than my old one! I guess it's working fine. I had to also get a catalytic converter in order to make my New York car smog proof certified in California.

2005 Volkswagen Jetta | Posted by | (Richmond, RI)

So this product is stated on CARiD as a cold air intake for a 2005 Volkswagen Jetta. That is a false statement. If you want the right sized pipe for a 2005 JETTA get the other series or a short ram. I had to buy separated hoses for the charcoal sensor and mass airflow sensor and they sent me the wrong sized hydro shield so that had to get zip tied on for the time being. Check engine light did come on and didn't go off. Had to clear the code. On the bright side, the intake gives the car an amazing throaty sound when you accelerate hard. The best sound is around 2000 and 4000 RPM.

The power gain from this is fantastic. Their range pulls and uphill speed gains are great. The installation took me a while, because you have to take the whole front bumper off and left headlight. But the slight frustration of installation was totally worth it. I recommend this part to everyone!!

The item was very easy to install. Like putting a sock on. It will help prevent dust and splashes of water but not too much water. If you soak it, water will get through and can get sucked into the motor from the air filter and lock your motor. Yikes. But this product does give you a little added insurance of such a catastrophe happening.
