Noticeable rpm increase. Feel a few more ponies. Pays itself off in 50K miles or less. Never can go wrong with a K&N. Been a fan and user of K&N filters for a long time.

Fit in my vehicle, arrived on time and cheaper option than buying regular filter. Thanks K&N for open direct purchase option.

Great product. I have used it in for my last two cars and will continue to use them in my next cars. Just the fact that you don't have to ever buy a filler for the rest of the cars lift alone is a reason to buy a K & N. I will be honest.. I think the next time I buy I will buy from a local retailer as with the exchange rate and the customs fees, I really did not save anything.. in fact I paid a bit more than I should have. But none the less I will always have a relationship with K & N. Kris
