K&N 33-2439 Air Filter Product Reviews

It increases engine response and acceleration as advertised. This is a must-have basic upgrade for every type of driver after the OEM filter is due change.

I have always used K&N Products for my vehicles. They perform as advertised, last forever, and improve performance due to better air intake. Simple logic. They appear expensive to a first time buyer until they compare how much the shop charges them to replace the factory filter. Great product. Customer for life.
