2005 Chevrolet Blazer 2D-4WD automatic.

Just got this vehicle and replaced filter with a K&N as I have with all previous wheels.
Blazer would hesitate while accelerating from a stop but now it shifts smoothly.

As with my other vehicles, I will expect to see some improvement in fuel mileage. For me,
it's not about the power gain, although that's nice when passing, it's about the savings.
In this day of high gas prices, every advantage helps and K&N provides it.

Have used various K&N air filtration systems over the years. Had a drop in filter on my 98 Ford Taurus(3.0 V6)and FIPK kits on my 97 GMC Jimmy(4.3 V6) and 92 Saturn(DOHC I4). Currently I'm using the kit from the Saturn in my 2005 Hyundai Elantra(2.0 I4)and a drop in filter on my 97 Moto Guzzi California (1100 V-Twin). No complaints other than not having a dedicated kit for the Elantra but the Saturn kit modded easily to it. Fuel mileage increases all around and noticeable power increase on the Jimmy. Considering purchase of kit for the girlfriend's Accord...

Gentlemen,
Proud to let you know I am using your air intake system on my 2004 Chevrolet Blazer "Extreme" and could not be happier with the increase in power, response and fuel mileage. This is the third vehicle I have incorporated your products into, and all vehicles have experienced the same positive improvements.

Sincerely,
