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.

Injen® - SP Series Cold Air Intake System with Blue Filter
Taking off the bumper was easy enough, but do it right and buy the plastic push pin clips because your old ones will break. That sound though...well worth the money. It comes with detailed instructions and the product is quality. Also if it rains a lot in your area buy the aqua sock too. It works and they offer it for a reason. Nobody wants there car hydro locked.

I was pretty skeptical on buying this intake because most g35 drivers by a z tube & a drop in filter & call it a day. The installation on this was not hard at all & didn't have to take off the bumper. The installation was really easy & only took about 1 hour. But buying this intake was the best thing ever! It completely changed the sound of my g35. I have a stick exhaust & when it hits rpm or switches gears you could hear the whistle & engine roars! I love this modification on the car. Really made it sound a lot more aggressive. I decided not to do the full cool air intake & just did a short ram intake. Basically all I did was leave out the extension pipe because if I did that the filer would be all the way down by the wheel well. Idk that's really risky if it rains in my opinion. So I just did the short ram. But it honestly looks & sounds amazing. Don't regret this buy at all. I love this cool air intake. If y'all have any question call the customer service because they are really helpful!

The product looks good and definitely adds a few hp. Also adds a little bit of a deeper sound from the exhaust. The installation would be the only thing I would change if I had to. It's not over exhausting, but by no means is it effortless. All in all a great buy.

The Injen intake is awesome, appearance is good performance is good. After installing it you can tell a difference in air coming in. You can hear a whistle once you accelerate and at high rpms you hear it growl, I like this product a lot, installation is DIY and easy.

Full installation required some time. Removing old intake and bumper took a bit of time. Great intake, awesome polished finish. Overall great product. Changing and cleaning filter requires a bit of time.

I don't know much about cars but I was glad to call in, and customer service helped me get what I was looking for and with a great price. I will be buying more parts for my husband very soon.
