Injen SP Series Cold Air Intake Reviews

Did not meet my expectations...

Reviewed By Nigel E (Rocklin, CA) Reviewed for a 2013 Infiniti G37 —3/11/2016 8:40 PM

The Injen intake looks like it's a well-made product and is very pleasing to the eyes as far as Esthetics goes but it honestly hasn't really seemed to impress me in the horsepower and fuel economy department. I was told this ram intake should get me roughly 10 to 14 hp gain. I was disappointed on the lack of actual hp gain which is barely noticeable. My fuel range has also gone from 15.6 to 13.4. Not exactly what I was expecting.

2009 G37X Coupe Re-Born

Reviewed By Rich E (MCKINNEY, TX) Reviewed for a 2009 Infiniti G37 —5/18/2015 4:14 PM

9 I bought this on a recommendation from a dealership service department. My hope was to eliminate throttle lag, give it a little more oomph on the go, and make it growl without being obnoxious. It gives me all of that. I didn't dyno before, and probably won't now. My butt-dyno tells me all I need to know. I got more than what I paid for. Great product!
