Lifetime Warranty

Spectre hpR Performance Air Filters: use high-quality washable/reusable cotton gauze; provide superior filtration; improve fuel economy; increase horsepower; and do not void manufacturer warranties.

Horse Power & CFM Rated
Each air filter has been tested on a SuperFlow 1200 FlowBench, the state-of-art of FlowBenches. The CFM & Horsepower ratings are what the filter will support in a naturally aspirated engine with no measurable loss to restriction. This is important to know if the vehicle had been modified for increased performance as it tells you how much power the filter will support. These performance air filters are rated at a much higher number than the requirements of the engine. Like speed ratings on a tire, it's always better to have more.
