    Injen Air Intake Systems

    Honda Civic 2011, SP Series Cold Air Intake System by Injen®. HP Gain: +8 hp. Torque Gain: +6.2 lbs. x ft. Includes: X-1014 Filter. The SP Series Cold Air Intake System is made for the enthusiast who wants maximum horsepower from a tuned cold air intake system. This cold air system positions a high-flow air filter behind the bumper, where it can take in cooler, denser air. Cooler air contains more oxygen for more complete combustion and more horsepower.

    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.

    Injen Technology Company, Ltd., based in Pomona, California, was formed as a sister company to RD Metal Works in 1998, to utilize the experience and design capabilities that RD Metal Works had gained designing and manufacturing air intake kits for leading air filter and intake manufacturers. Since that time, the company has made it a point to stay at the forefront of performance technology, continually setting new standards for quality and improving their engineering and manufacturing capabilities. This enables Injen to regularly introduce new, cutting edge products to market and has required the company to continually expand to meet the demand for those products. Today, Injen continues to set the industry benchmark for innovation, styling and technology.

    The Magnusson-Moss Warranty - Federal Trade Commission Improvement Act of 1975 protects consumers from such fraudulent activity by new car dealers. Under this Act, aftermarket equipment that improves performance does not void a vehicle manufacturer's original warranty, unless the warranty clearly states the addition of aftermarket equipment automatically voids your vehicle's warranty or if it can be proven that the aftermarket device is the direct cause of the failure. The easiest way to check this is to look in your owner's manual under, "what is notcovered". Under Magnusson-Moss Act a dealer must prove, not just vocalize, that aftermarket equipment caused the need for repairs before they can deny warranty coverage. If they cannot prove such claim-or offer an explanation - it is your legal right to demand compliance with the warranty. The Federal Trade Commission administers the Magnusson-Moss Act and monitors compliance with warranty law. Ct cause of the failure.

    Injen CAI
    Love this product. It looks great and sounds even better. Haven't really noticed a gas improvement but for sure a sound and performance improvement. First of many mods to come. Cant wait to put the Injen sticker from the package on my Civic window. Thanks a lot to the guys over at Injen! The only thing, i would say is make sure you install your Mass Air Flow Sensor in the right way. I had mine in the wrong way and thought i was loosing air somewhere. Took an extra hour and a bit of frustration and anxiety to figure out a simple turn around was the answer.

    Cold Air Intake
    Amazing. I love the sound of it when you can hear the air just flow into your motor. I found a difference in power and so did my friends when I took them out in my car.

    This Cold Air Intake Delivers
    Instructions could have been a little more clear from Injen. Other than that i am completely satisfied with every portion of this order and part. Got considerable horsepower gain and the torque is where I really saw improvement for my 2008 Civic. Highly suggested for the more mechanically inclined. If your looking for something really quick and easy, go Short Ram style. Either way i'm one happy customer.

    Great Intake!
    Has an awesome deep sound even with my stock exhaust. Was super easy to install, and looks really cool under the hood! It is worth the price unless you live in Canada, i had to pay an extra $30 for the currency exchange and there was an $82 import charge.

    Cold Air Intake on 2009 Civic
    After installing my new cold air intake, I took my 2009 Civic out for a spin. The power did not drop off as early. A bit of air noise comes with full acceleration. Removing the air intake muffler is part of the installation. Pulling the left front wheel lets you partially remove the front inner fender, giving access to the area where the new filter will be. The instructions show the car with the bumper removed, but do not tell you how to go about it.
