Injen RD for 2005 Altima 2.5

Posted on 07/27/2006 by Chris M. - 2005 Nissan Altima (Chandler,AZ)

2 of 4 people found the following review helpful.

"Quick install, total of 1 hour to take out old one and put in the Injen. Very nice look, love the sound, and definitely notice the extra kick off the line. Not too noticable of a difference in HP. Highly recommend the Injen CAI."

WOW..!!!! BEST PURCHASE EVER MADE FOR MY CAR

Posted on 05/09/2006 by Anibal M. - 2004 Nissan Altima (Hackensack,NJ)

"Injen makes great products and this one is no exception.. it gives the car a few extra horses and you can feel that extra torque right away.. but once that tech goes over 3k RPM the sound that comes from the injen is ... you can't describe... it's that injen sound.."

"My intake is very well made and I expect it will out perform every other brand. The location of the filter head gives you the very best source for cold air. Problem, to install it on my 2003 Mazda Protege5 it requires I remove all of the front body work to get to where the filter head goes. What is even worse, you have to do the same thing every time you want to service the filter head. If you pay someone to do it, your looking at big bucks. If I knew that going in, I would have gone with the AEM which I have always found to be excellent and easy to install and service."

"I'd have to say the sound from the Injen intake sounds amazing. The loud deep roar of the CAI as you get onto roads and after stop lights just sounds great. Also the jump from the horse power and torque are very noticable as well. all around great product."
