K&N 33-2448 Air Filter Product Reviews

Purchased the 33-2448 K&N for my 2014 Kia Optima LX. Wow. What a difference in power. After I cleaned my intake and installed the filter, I immediately noticed a big difference in power & torque. Well worth purchasing. Don't be fooled by those other, cheap brands.

I now have K&N products on all my vehicles. I am very pleased with the improved throttle response on our 2012 Kia Sorento. Will continue to buy and use K&N products, even on my son's Jr Dragster.

Very Happy with my K&N products. K&N never disappoints with their performance, design, and quality. I did a simple upgrade with an air filter (33-2448) on my 2014 Kia Optima and have noticed 2-4+ mpg increase and noticeable throttle response difference. Also thankful the company employs awesome people who are passionate about their work and are so close to home. The cheap knock off filters just don't compare.
