See improvement in smooth acceleration.
Allan, Rosamond, Illinois
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.

The very best airfilter I have ever used.

Dustyn Arney, Chesterfield, Missouri
I reset my average MPG display when I installed these a few weeks ago, and I'm tracking about 1MPG better than I have since I bought the car. I'm very pleased with them.
Maciej Szara, Franklin Park, Illinois
Great product, quick ship. Can feel the difference in acceleration on my q50s hybrid.
E.J. Amo, Jupiter, Florida
Recently purchased 2 of these as replacements for 2014 Q50. The filters fit perfectly and I'm sure I will get a lot of life out of them. I purchased a K&N filter for my last car and drove over 100k miles. They are easy to clean and I don't feel any loss in HP.
