Oil-Free Filtration
AEM DRYFLOW air filters do not use oil so there is no chance of over-oiling your filter which takes the guesswork out of servicing.
Easy to Clean
The DRYFLOW filter uses environmentally friendly, mild, all-purpose cleaner. Simple cleaning instructions. Under extremely dusty/dirty conditions, DRYFLOW filters can be knocked a few times to remove excess dirt off of the filter pleats. DRYFLOW filter media is so durable that it can withstand almost unlimited cleanings and also resists water absorption.
Warranty-Safe Filtration
DRYFLOW air filters will not void your warranty. Sheds Dirt Under Vibration
AEM’s unique non-woven filter media does not require oil to filter and trap dirt and contaminants, and as a result an open air filter actually sheds dirt under engine vibration, unlike cotton-gauze which holds on to contaminants until you clean the filter.
