Spyder filters exclusive and proprietary Engine Defender Technology™ stops and holds dust 4 ways.
Both are highly demanding applications! We build maximum performance filters for each.
We don’t make air filters that simply fit dirt race vehicles. We design, engineer and manufacture precision filtration products specifically created for the significant demands of high-performance dirt racing applications!
We engineered our advanced, Nano-Tech EX media web with multiple layers that are permanently bonded together. Each layer is specifically designed to perform a unique and vital filtration and permeability function and this synergy creates an outstanding product that outperforms every other filter used in dirt and off-road racing.
Prior to our design work, extensive evaluations are performed by a team with over thirty years of dirt car and off-road race filtration product experience. In order to produce the best performing air filters in the business, it’s vital to fully understand the environment in which the products will operate.
The lab and test benches tell us a great deal about what race teams face in terms of important air filter criteria. We analyze post-race filters to determine dust particle size, concentration and the amount of loading that has occurred.
Designing professional, high-performance filters that are unmatched in each category of measurement requires that air flow, gravimetric and fractional efficiency, and dust holding ability are all precisely engineered to ensure maximum performance for each application. Spyder dirt racing filters stop and hold particles as small as .1 micron while featuring very high dust holding capability, maximizing power from green flag to checker!
Our filters are so effective at keeping race engines spotless, they can stop airborne smoke! Never again will racers have to deal with fine dust on the air cleaner base, carburetor and what has collected in the oil pan. Spyder filters dramatically reduce silicon (dust) ingress and oil sample testing routinely shows single-digit ppm counts. No more premature cylinder wall and valve wear caused by dust entering your engine.
Over 98% of the dust you'll encounter is .5 micron or less! And this fine dust then aglomorates or "clusters together" forming a sinister film or a cake-like sludge in the oil pan.

Spyder filters are also robust in design and can take a beating!
It’s a miserable feeling when you’re behind the wheel and you watch flying debris hit your car, and more importantly, the air filter. What can you do? Early in the race and going for the win, you simply hope for the best. Count on us for help.
Spyder dirt racing filters are designed with a strong inner and outer screen that protects the filter media in the event of impact from debris. In addition, our filters also feature an inner mesh safety barrier that is pleated and potted into the urethane along with the media. This safety mesh mitigates the chance that impact damage may allow dust leakage and potentially expensive engine damage to occur.
