Product Details

SP Series Polished Silver Short Ram Air Intake System (SP1977P) 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.

Absolutely Love It!
This intake system is well worth the money! It looks clean, simple to install and produces some gains. I haven't been able to any dyno runs to see if hp went up but the throttle response is so much better now with it. And again it makes the car sound a lot nicer! 09 Altima coupe 3.5l.

Love It!
I absolutely love this intake. From the moment I opened the box I knew it was Premium Quality! It is nothing shy of perfect. The installation is so easy that even a first time replacement is done simply. I know this because it was my first time replacing a whole intake system, and it was done just by myself. It only had taken me 1 1/2 hours from start to finish, just follow the instructions. Then, when I finally took it for a drive, the sound caught me by surprise, because it was louder than expected. The best part about my intake though is that I used to get 32 mpg highway. Now, I get whomping 46 mpg highway! Only when I drive it like a town car though. If I race the engine, I only have about a 3-4 mpg increase. This intake was placed on a 2011 Nissan Altima 2.5 S Sedan.

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.

Extra Power
I just put on my 2018 Mazda 3 2.0 liter and I believe everything they say is true. More hp and and torque and better gas mileage. Really a quick installation and love the extra torque. The torque is what I missed the most especially at lower rpm. Great product.

Perfect
Let’s be real here, you wont notice any power gains from just an intake. You will however notice how much louder your car is afterwards. I’ve had people asking what kind of work is done to my car only to have them shocked that the intake is the one making the noise. This thing is super easy to install and will definitely make you smile every time you give your car some sauce. Perfect for a beginner if you’re looking to start making some changes.
