Review on K N RK 3933X Intake System by Joe Farrell

I recently purchased a top-of-the-line car filter and the difference it has made in my automotive is astonishing .Thanks to my knowledge gained in practice and research, I knew that this upgrade would make all the difference. The improved air flow has significantly boosted my car`s performance. The only DOWNSIDE is the initial cost but the long-term savings on gas and maintenance make it worth it in the end. I highly recommend upgrading your car filter to really optimize your vehicle..
