Product Details

SP Series Polished Silver Short Ram Air Intake System (SP1121P) by Injen®. The Short Ram SP Series is a traditional, underhood air intake system that takes the place of your factory airbox and air filter, and the factory air intake tube. The EA Nanofiber air filter allows increased airflow and the aluminum alloy intake tube smoothes the airflow path into the engine. The increased airflow and velocity results in more power, increased acceleration and better fuel economy.

Installation

Just because the Injen SP Series Short Ram is a traditional "underhood" system, don't think it's any less of a performance air intake system. The SP Series Short Ram is a product of the same rigorous development and testing as Injen's other air intake systems. It's made of the same quality materials and features the same high flow EA Nanofiber dry air filter. The air intake tube is made of 6061, T-6 aluminum alloy, for strength, light weight and smooth airflow. All connections are made with quality silicone connectors that provide flexibility, while maintaining strength and thermal stability. The stainless steel hose clamps provide a solid seal that won’t loosen or deteriorate. The end result is a quality system that will improve performance and look great under the hood.

Where the SP Series Short Ram differs from conventional short ram systems is the inclusion of Injen's patented MR (Mega Ram) Technology. MR Technology allows this system to attain 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 Short Ram system installs in place of your factory airbox and air intake tube. It's carefully engineered, with CNC machined brackets and adapters, to ensure an exact fit. Installation is fast and simple and can be completed under the hood. There's no need to get underneath the car or do any significant component relocating. Everything necessary for installation is supplied, including comprehensive instructions. The SP Series Short Ram Air Intake System is backed by a Limited Lifetime Warranty.

Great Intake
The intake looks really nice in the engine bay. It fits perfectly if you follow the manual given. I got the installation done in half an hour with no prior skill. Also gives a deeper tone to the exhaust as a bonus.

Great Part
Beautiful intake with instant horsepower you can feel. A bit on the pricey side but definitely worth it if you want a legitimate modification with legitimate power and torque gains.

Fun, Easy, and Looks Great!
First of all, I love the option of the black coated tube. I like things to match so the black and blue product looked great next to the BMW logo. Plus, I installed it myself. Great instructions, very simple install. As for performance, I'm sure I feel a bit more peppy. Very satisfied overall.

I Should've Done This Long Time Ago!
I never knew that simple changing the air intake can significantly increase the feel and performance in driving. I should've installed aftermarket air intakes to all of the other cars I owned. I absolutely love it!

Good Investement
That is my 2nd cold air intake that I used for my cars. U can feel a little bit more pick up in your car and the way it sound it's amazing I love it. You would never regret buying and installing it in your car, and if u r a little bit familiar with cars and engine there is no need for a mechanic to install it for u. You can do it yourself. In about 45 min you can have the job done.

Know What You’re Buying
Like the title says, know what you’re buying. This means just because its a fancy tube does not means it’s a turbo and you will not notice any power gains from driving alone, on the dyno you might. Buy this if you are doing it for sound and engine dressing. It definitely makes your engine bay look better and it definitely makes the growl of the car more aggressive. It’s a great product for what it is, the bad reviews come from people that are expecting much more.
