Customer Feedback

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.

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.

I just wanted to say thank you to the people at K&N for their sponsorship of truck and tractor pulling. I spoke with one of your representatives at the ATPA Winternationals in Fort Wayne, Indiana in January about a new air filter for my 1998 Chevy Blazer. Based on my discussion with that gentleman and seeing how your products improve the performance of my favorite truck and tractor pullers, I decided to purchase an air filter. My gas mileage improved immediately and I did notice a slight increase in power. Following my positive experience my father purchased an air filter for his 1998 Chevrolet truck. My best friend also purchased a filter for his 1999 Chevrolet Silverado. Overall, we are all pleased with this true "bolt-on" increase in power. I am by no means any type of mechanic, but it makes me feel good to be able to add performance to my vehicle. I had heard of your products in the past, but without the sponsorship of pulling, I would have never been pushed over the edge to purchase your products. Thank you!
