Excellent filter, works and sounds great-long lasting
Great fit, this was the replacement for the previous filter of the same type which has been on the vehicle since 2007 with no issues. Love AEM filters and charge systems

GARBAGE
garbage. 1) inspect the inside. mine was full of debris and shavings from the rubber. 2) the inlet hole was completely missed in their manufacturing process. No reaming was done and there were gigantic flakes of rubber ready to be dislodged and inhaled by the engine. 3) straight through hole in the end cap of an air FILTER. Why? Stupid. Let's bypass our air filter and allow unfiltered air into the engine. 4) the mesh was screwed and had pieces poking out of the filter 3/4" long.
