Injen SP Series Cold Air Intake Reviews

Rx8 review

Reviewed By Andrew J (LA CENTER, WA) Reviewed for a 2004 Mazda RX-8 —1/14/2016 3:23 PM

It works well for the car. Make sure everything is sealed when installing. It's not a true cold air but it only runs 12 degrees warmer than ambient temp and only 2 degrees than stock. For the sounds and looks it's worth it and there's more torque. As for the 20 extra hp well it's more like 10 hp.

I had to disconnect my air box to clean my air filter, so installation wasn't too bad. Can't say I've seen any benefit thus far in power or mpg.

Big let down

Reviewed By Josue T (Kissimmee, FL) Reviewed for a 2004 Mazda RX-8 —6/12/2015 8:13 PM

This product was a big let down. Sounds horrible and gas mileage decreased significantly. Removed from car 2 days later. I Wish I could get my money back.
