No longer is there a need to risk dust and dirt entering and damaging your vehicle's engine!
OTR Extreme Series air filters are designed for the most grueling conditions you will encounter and will keep your engines clean!
One of the first and most important things you can do for your vehicle is to eliminate any factory air filter problems. OTR offers replacement, reusable air filters that eliminate engine damage, stopping dust and dirt dead.
The factory cellulose (paper) and foam filters offer fractional efficiency of approximately 30% on very fine dust. OTR air filters raise the fractional efficiency by almost 3 times over the stock filter, keeping your engines clean in the most severe conditions!
OTR Extreme Series air filters offer unmatched engine protection and easy maintenance in a long-life, oil-free, high-performance air filter. OTR tough, synthetic fiber structure stops and holds dust to .3 microns! These filters rely on advanced military media technology and are designed for severe-duty use. OTR air filters will outperform every competitive filter produced for your application. They're incredibly easy to maintain too! This specially designed filter media allows you to remove dust using compressed air from inside-out or vacuum the exterior. While not often necessary, OTR filters are also washable for long-life performance and value.
It's not a bad idea to have your engine oil analyzed from time to time. This provides a good barometer of how well your air filter is performing as well as giving you a good general idea of lubrication efficiency. We perform these tests regularly when designing filter media for each specific application. Compare silicon levels between OEM and other aftermarket filters against OTR Extreme Series filters and you'll quickly see the significant engine protection benefits.
