Injen SP Series Cold Air Intake Reviews


A noticeable improvement

Easy to install. Even with a back injuyy it only took about an hour. It provided a notable increase in torque and HP. It seems to have increased optimal RPM's. Squeeling tires is now possibly in 2wd in "Normal" driving mode. It does let you hear more turbo spool too.

I like it a lot. You can go longer intervals without cleaning and repel water as well.
