Injen SP Series Cold Air Intake Reviews


Decent...but kills MPG

Reviewed By Michael G (COOS BAY, OR) Reviewed for a 2014 Nissan Altima —11/18/2014 11:42 PM

Looks good, sounds good, easy to install. Lost mpg on the highway...was getting between 40 and 50 MPG on a flat in the highway at 60...now its more like 35 to 40mpg...a little faster on the draw though...seemed to cut the acceleration delay in half... would not get another one due to the MPG cuts...no its not my driving...

Injen IS Series Short Ram Intake Reviews


Now I can breathe!

Reviewed By ANTHONY C (TUCSON, AZ) Reviewed for a 2001 Nissan Altima —10/4/2012 10:18 AM

Installing the new intake was not difficult, just a few hand tools and about an hour including cleaning the throttle body. Definite gain in power and throttle response. You may want to consider a tune up at the time of installation, I needed to adjust the engine idle speed due to the increased airflow. The short ram looks great under the the hood too!

Injen Rd series cold air intake

Reviewed By Brian M (Lansdale, PA) Reviewed for a 2002 Nissan Altima —7/1/2010 10:11 AM

The Injen cold air intake went in with ease. just follow the steps and its a piece of cake. I'm definitely happy about my purchase. The car has more torque off the line and has that sweet INjen sound after 4000rpms with the pedal down. When driving regular its just as quite as stock. I also noticed a slight raise in Mpg, nothing to crazy. As far as horse power, cant really tell, I'm sure a little. My car is stick and it seems that the intake has made transitions through the gears a lot smother, also I had a slight hesitation in the throttle that was cleared with the intake. Filter sits right behind front left fog light, so I took mine out to get better air flow. This intake is a gotta have in my book, will buy one for each of my future cars.
