An inexpensive way to start is just by replacing that paper air filter. It filters the air, OK, but the small passages are very restrictive, and as dirt builds up, the flow gets even worse. A typical aftermarket performance air filter has several layers of filtration material like cotton gauze, which traps dirt without restricting airflow. What’s more, aftermarket filters can be cleaned and reused, so you get increased engine power and save money to boot.
But to really get an increase in airflow, you need to increase the size of the air filter. The typical conical air filter that is included with an aftermarket performance air intake is not only made of better material, but it is also larger and has much greater surface area than the OE filter, for much greater airflow. An economical way to get the benefits of a larger filter is with one of our kits that attaches the filter to a flexible, universal intake tube, or attaches it to the factory air intake tube. The next step up to greater airflow is to replace that restrictive OE air intake tube.
