Should I get the red one or gray Brute Force? Looks like the red ones have the metal screen and only some of the gray Brute Force ones have the inner structure support.
Durable AEM Universal Clamp-on Air FiltersAEM 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 thick red colored oil-free filtering media.
Our other clamp-on air 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 but not as rigid (???) since they don't contain screen. There is no risk of filter damage during shipping, installation or cleaning. These Dryflow® filters will retain their shape and performance even after abuse. Most Brute Force Dryflow filter elements are reinforced with a lightweight mineral-reinforced plastic cage that maintains the element’s structural integrity and prevents the filter from collapsing from flow demands.
