Hyundai Sonata 2.4L 2011-2012, SP Series Polished Cold Air Intake System (SP1331P) by InjenŽ. 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.
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.

Amazing! Very easy to install, of course, if you have some mechanical skills! No tune need, feels difference Especially on the highway. Better engine sound if you combine with the right blow-off valve! Highly recommended!!!
Only thing that was tough was finding the nut to get the old system detached from the turbo. Looks great and sounds great. Also, I've got better gas mileage, 3 mpg better.
I am pleased with the fit. Harder to install on the turbo due to having to go down and under to reach nut. The engine bay is pretty tight with no under vehicle access. Was a little worried when I first heard the motor, when you get on it, sounds like a weed whacker!!! After initial concern had past, I now get all over it and find a good power boot in all gears. No check engine light came on which was a concern. With the power and air flow increased you can get some sound out of the stock blow off valve. You should include the air flow box arm adapter that secures the stock air director in place. Might be an extra that I passed on not knowing. Overall I did not see as much power as I had in past vehicles (08' Tundra 5.7 - 03' 350Z ) but had never applied such intake to a 4 cyl. Would give it a huge thumbs up and makes for a great upgrade to the turbo.
