As most of you know, the E46 air filter was shorten in height and a foam prefilter was glued onto the filter element. I have found that the E36 air filter does not have this glued on foam prefilter and adds more filter element height. The result, more filter surface area and no dead spots were the glue was applied.
The E36 filter fits perfectly and provides an increase in air flow to the engine versus the E46 filter. I recommend Mahle/Knecht or Mann only.
