AEM 21-203DK 75мм X 130мм

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. 

Durable AEM Universal Clamp-on Air Filters 

AEM Universal Clamp-on air filters come in two basic types. Our standard Dryflow™ air filter has screen wire for rigid structural strength. These filters have a red colored oil-free filtering media. Our other clamp-on filter is our Brute Force Dryflow™ air filter. It is a durable filter that is a favorite in rough, dusty racing conditions. These filters have a gray colored filtering media. They are very durable and not as rigid.

Brute Force Dryflow™ filter media bounces back to original shape 

The Brute Force Dryflow™ media is tough. There is no risk of filter damage during shipping, installation or cleaning. These Dryflow™ filters will retain their shape and performance even after the most severe abuse. That is why winning race teams continue to choose the AEM Brute Force Dryflow™ air filter. 

Strength from the Inside Out* 
We reinforce round Brute Force Dryflow™ filter elements with a lightweight mineral-reinforced plastic cage that maintains the element’s structural integrity and eliminates the chance of the filter collapsing from flow demands, while also reducing the filter’s overall weight.

* Note: Dryflow™ Panel Filters are supported by co-pleated aluminum wire mesh. 

Air Flow Capabilities 
Every Dryflow™ air filter is engineered to exceed the normal flow capacities of the engine it is required for when clean. For example, a typical naturally aspirated 2.0L engine requires 253 CFM of flow. The filter we manufacture for a 2.0L Acura RSX Type-S (21-204DK) delivers up to 565 CFM of flow when clean. You get great flow with Dryflow™, in addition to outstanding filtration and excellent dust holding capacity. 

Diesel engines require massive air flow. AEM has responded with a filter that dramatically exceeds that requirement without compromising filtering efficiency. For example, the AEM BFS-HD (PN 21-9221D) for the 2007 Dodge 6.7L Cummins Turbo Diesel exceeds the stock induction air flow by 84% when clean.
