Product Details

SP Series Polished Silver 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.

Installation

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.

I very satisfied with Injen Intake. I was not expecting that much power, and the sound is impressive. Easy installation, it took me like 45 min.

Nice Sound, Not Too Loud, and Noticeable Power Gain!
Installation was pretty straightforward and easy, only downside is taking off the front bumper which was kind of time consuming. I am very happy with my purchase and will recommend for other Hondas.

Great Intake for the Price
For my 04 Acura rsx it required us to take the front fender off completely take out. The windshield reservoir and it comes with a replacement reservoir so the intake can fit we had to cut into the fender well not much but about 5-7 inches deep into it so the cone could fit in the compartment in front of the fender well. It took me and my dad who are both mechanically inclined 3hrs and it requires several tools... all in all it is a solid product I got exactly 12 hp gain from it and it was fun putting it in with my father, but be warned if u are not mechanically inclined or just an amateur I would highly recommend getting this professionally installed.

Love It!!
Was easy to install with the directions that were supplied with it. I also watch some videos on YouTube.com before doing myself to see what stuff to look out when I'm in the process of disassembling the front bumper and reinstalling it. Before install my vehicle had a quiet sounding bypass relief sound and now it sucks air like crazy and you have that loud relief sound. Love it I definitely recommend this product
