This unit made a big difference in the engine breathing and acceleration. I am more than totally pleased. It looks great too. My Jeep Wrangler Unlimited is only rated at 190hp. I am confident the Injen Cold Air added at least 10 hp. Thanks for a great product.

Amazing improvement in overall performance. The only problem with the install is the MAF rubber bushing. The one issued with the unit tore very easily and it was more than a notion to locate another one that would fit the hole and the MAF sensor. I would suggest the manufacturer install the rubber in the pipe and furnish a spare. You could be in trouble if you don't have a lot of stores around who might handle the rubber grommets in the size required for the MAF. This unit was installed on a 6 spd manual tranny. High gear, low speed performance, hills and general cruising was quite an improvement over the factory system or just a K&N filter in the air box. Gas mileage is about the same and maybe a bit better. Too early to tell with any improvements in gas mileage.
