I can't see why anyone would use a Racing filter on a street machine.

We offer two very different and distinct racing filter lines. For maximum flow and horsepower the lowest restriction pure racing media filters are recommended – oil (T-10) and air (T-66). However, when endurance and better engine protection are needed, WIX’s high efficiency endurance media filters are the correct choice – oil (T-71) and air (T-88).
Racing filters are not intended for street use and often void new vehicle and equipment warranties. Installation on a street or highway driven vehicle may be a violation of state or federal law.
Different filters for different purpose and conditions. Micron ratings are WAY different.
