Air filtration is all about maximum cleanliness of air going to the turbo with (efficiency) with the lowest initial restriction when the filter is new and clean. IMHO K&N will slightly reduce your restriction but will not give you the cleanliness efficiency your engine wants. If your running all pavement, minimum fine dust...probably OK. For my $ I stay with the OE system that has had hundreds of thousands of dollars in research spent on it.
100 % agree!
MAF sensors do not like K & N! Stay with OE
