    Nissan Altima 2004-2006, SP Series Cold Air Intake System by Injen®. 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.

    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.

    FACTORY WARRANTY
    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.

    Altima
    Installed this intake in less than 2 hours, including the time it took to drive to a hardware store for a tool i needed. Installation is very straight forward and if there is confusion, the instructions give a good kick. Where it bolts to the body, the fit wasn't perfect but a little muscling gets you over the desired screw. The finished product looks great compared to stock, sounds much better, and does give the small added power it claims. I'm happy with it!

    Best Intake out There
    I love this intake. It's honestly the best. You hear the intake just taking in all the fresh cool air right after you changed your stock intake. You feel the power, I swear. And, wow, the roar it gives, when it gets to the high RPMS... Unreal. Simply amazing. Sounds beautiful. Buy it. You won't be disappointed.

    Amazing!!!
    I purchased the intake and just over a week later it was in my 2006 Altima. It absolutely roars. The ability to switch from SAR and the complete CAI is so useful. Definitely recommend this if your looking for any car to kick you back into your seat and pass anyone in any gear and listen to the deep belowing sound.
