Turner Motorsport is turning GREEN! The product of a cutting-edge manufacturing process and advanced air-filtering technology, Green High Performance Air Filters™ deliver improved engine output and enhanced performance, providing an average 5% horsepower increase over standard paper filters.

A Green Filter is also a smart investment. Paper filters typically retail from $10 to $15, and are recommended to be changed every 3,000 miles or with every oil change. After one year of driving and replacing a paper filter, a Green Filter - which never needs replaced and  requires only occasional cleaning - is generally paid for. As well, all Green Filters carry a limited lifetime warranty.
The product of years of extensive research and testing, Green Filters feature unique design elements allowing for improved, sustained airflow and filtration down to 5 microns. Most common high performance filters are made from layered cotton gauze, a material that wears quickly and allows oil and worn cotton to be drawn into the engine from intake pressure. Green Filter eliminates these problems with a 2-layer, woven cotton design. The interlock weave creates a thinner, more durable filter that ensures consistent airflow over time and allows for repeated cleanings.

To prevent air leaks around the seal, Green Filter utilizes an inventive rigid pleat design to help the edges around the rubber stay sealed to the air box. Green pleats are aligned parallel to the width so that more pleats can be fit to the filter. The result is a greater surface area allowing for better air passage and improved engine power.

Where many other filters employ a pressure mold injecting process to speed up manufacturing, Green Filter utilizes a precise four-stage, handcrafted molding design. Injection molding frequently results in 20-25% blockage of the flowing surface area due to rubber spillover. By adding extra quality measures, Green ensures that its filter moldings are almost exact around the edges – eliminating wasted surface area and improving overall airflow.
