Product Details

SP Series Polished Silver Cold Air Intake System (SP1978P) 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.

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.

Great
This intake sounds great and adds noticeable power in the car. The problem is where it mounts. It mounts right on a ground wire and I have a problem of it becoming loose and messing with the electrical so I took a pipe off and it still runs great

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.

It's Really Good
It looks good, and performs well. It was a bit tough getting the the factory sensor in without breaking it though. I feel like that could be designed differently. Also, no stickers are shipped with the intake. You have to pay for them separately.

Great Cold Air Intake. Beware of Danger.
High quality intake that fits perfectly in place, the installation was smooth and the performance/sound was noticeable. As with any CAI and specially the Juke any type of low/high puddle/flood will water damage the engine badly as a result of the filter being so low to the ground.
