Injen Air Intake Systems

SP Series Black Cold Air Intake System (SP1331BLK) 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. Up to 7 HP and 7.5 ft.lbs TQ Gain.

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.

2012 Kia Optima Cold Air Intake
Injen® SP1331BLK - SP Series Cold Air Intake System (Black)
Fit perfectly in my Kia Optima. Opens up the engine bay tremendously. Took me about an hour for the whole installation. Instructions were easy to follow telling you what to do step by step. I could hear the difference in the sound of the car as soon as I pulled out of the driveway! You can just hear the air s*cking into the intake as you accelerate! I'll give this product 2 thumbs up! Great quality and great sound! This is a great upgrade for your car that I would recommend to anyone trying to improve sound and performance!

Really Awesome Intake!
This is the 3rd CAI i've installed over the years and this Injen CAI is the best i've experienced by far. I mainly bought it to beef up my 2011 Hyundai Sonata a bit but the sound it puts out is absolutely amazing and well beyond expectation! My car sounds very beefy and resembles that of a muscle car. It carries my favorite low, rumble growl during acceleration. Nothing cheap or whiney about it and i've even turned a few heads in passing. Oh and i even got a bit of a boost in speed. not by much since i didn't gain very much horsepower, but since my engine is able to breath better im reaching higher speeds quicker and during manual shift the gears last longer before switching over to the next. I love this product and makes me proud to have it. I plan to continue shopping with CARiD now that i feel it's a trusted company. Thank you.

I am pleased with this product. The HP gain isn't as amazing as I expected. However, my car now has a nice deep rumble when I accelerate, which is good enough for me!
