Spyder™ High Performance Air Filters are so effective at keeping race engines spotless, they can even stop airborne smoke.  Never again will racers have to deal with fine dust on the air cleaner base, carburetor and the implications of what has been 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 an engine.  Spyder™ Nano-Tech EX™ dirt racing air filter media stops and holds particles as small as .1 micron and provides very high dust holding ability, maximizing power from the green flag to the checkered.   Racecar Engineering™ is proud to distribute and support the entire Spyder™ High Performance Air Filters product line.  Shop here online now for the most popular items from Spyder™ High Performance Air Filters.  Always remember, if you don't find what you need on here our website, we'll gladly special order the item for you directly from the factory.  Please contact our Technical Sales staff for complete information.
