Imagine being able to install a large, high-flow, conical performance air filter in your factory airbox. In effect, that's what happens when you install a Super Stock IRF air filter. Its unique inverted design maximizes the use of the available space inside the factory airbox, allowing the installation of a filter with up to 76% more surface area in the same location. Airflow is increased up to 90% and dust holding capacity is increased by up to 65% versus the stock factory flat panel air filter. But the shape of the IRF is only part of the story, because this filter features the Pro DRY S filter media.

The Pro DRY S filter media combines high airflow and filtration efficiency with the convenience of oil-free maintenance. It contains 2 layers of randomly porous synthetic fabric, which allows approximately twice the airflow when compared to a typical stock air filter. The increased airflow results in more horsepower and torque, better throttle response and more miles per gallon. But this improved airflow and performance hasn't been gained at the expense of engine protection. The Pro DRY S has an excellent 99.2% filtration efficiency rating.

The pleats are evenly spaced for greater dust holding capacity and the tips are rounded for better airflow. The sealing surface and supporting structures are made from 100% polyurethane, to withstand extreme engine temperatures.

Under normal driving conditions the Pro DRY S won't need servicing for 25,000 to 30,000 miles. When service is required, the Pro DRY S can simply be washed and dried and put back into service; no oiling is necessary. The Pro DRY S can be washed and reused repeatedly; you'll never have to buy another air filter, ever. The Super Stock IRF air filter is backed by a limited lifetime warranty and it's made in the USA.

The installation was straight forward, just like installing the factory filter. Perfect fit, my truck seems to be more responsive. Can't say about fuel economy, don't know yet.
