    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 SP Series Cold Air Intake System.

    Injen starts the power improvement process by positioning an Injen EA Nanofiber dry 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.

    MR technology

    But unlike other cold air intake systems, Injen's patented MR (Mega Ram) Technology attains this increased intake airflow and performance while maintaining a safe air/fuel ratio. Injen steps down the diameter of the intake tube where the Mass Air Flow (MAF) sensor mounts, enabling the sensor to detect airflow within established parameters. The engine control computer can then maintain the proper air/fuel ratio and optimize horsepower and torque. Simply put, MR Technology tunes the intake system to avoid the necessity of recalibrating the MAF sensor, and prevents your engine from running too lean or too rich. With MR Technology, Injen created "The World's First Tuned Intake System", delivering optimum performance with a factory safe air/fuel ratio.

    The SP 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 SP Series Cold Air Intake System is backed by a Limited Lifetime Warranty.

    Hydro-Shield Pre-Filter
    2013 Volkswagen Golf Gti
    | Posted by | (Stephenville, NF)

    I recently ordered the Injen intake and hydro-shield pre-filter. On my 2007 Mazda 3, the intake is in the driver's side fender by the vents around the wheel. It rains a lot where I'm from, Stephenville, Newfoundland, Canada, and I didn't want my intake sucking up water. I had this for about six months now and never had a problem. I definitely recommend using this because I have friends who blew motors by water being sucked up through the intake. It's worth spending the extra money to get a hydro-shield for protection.

    The pre-filter doesn't look like it does much but I have driven through some good snow and rain and have not yet to have a problem. It's a good extra measure of security. Might as well add it to the cart.

    This black sleeve complements both the polished and black intake. I'm not in a rainy state, but I figured I would purchase the Hydro-shield Pre-filter just in case. It doesn't hurt to be prepared or protected.
