  • BETTER FLOW, MORE POWER!

    At GrimmSpeed, they know that not everyone is ready for one of our full aftermarket intake systems, but still wants a safe and easy way to increase power with no tuning required. GrimmSpeed worked hard to develop a direct replacement, dry-element air filter for the stock airbox that not only decreases restriction, producing more torque and horsepower but is also able to filter out particulates at the same level as the OEM filter to keep your engine safe.

    WHY CHOOSE GRIMMSPEED?

    Filter design is a delicate balancing act, the overall goal of creating a good air filter is to find the ideal combination of flow, filtration efficiency, and holding capacity. There IS a difference between simply making a unit that fits in a factory intake box and engineering a performance air filter.


    Some air filters are constructed with cotton or synthetic media combined with oil to increase filtering ability. This can increase flow, however, it also means more difficult filter maintenance because of the need to properly re-oil the filter. GrimmSpeed decided to use a dry-construction media, utilizing two different layers of synthetic material with varied filtering and flow abilities, resulting in very similar flow capability to the oiled media while maintaining the same filtering efficiency. Since other important variables in air filter design including the pleat pitch, count and depth can make or break the performance of a filter, extensive testing was required.
