It came very quickly - great service It's a little thicker than the OEM filter element, so it took a little persuading to latch the top down on the filter housing. I'm waiting to see if there are any immediately-noticable benefits vs the OEM one.

Great product, as always!

Just purchased a K&N drop-in air filter for my 07 BMW 335i and I am very pleased with the results. It gave my exhaust a throaty-er sound and helped with acceleration too just like K&N claims. Overall it is a great product at a great price.
