Excellent. I notice an improvement in acceleration immediately. I am looking forward for K&N coming out with a new line of cold or hot intake for the 2015 Infiniti Q70L 5.6 v8.

I have been using K & N filters in all my cars for the last 40 years and will not buy a new car without changing the filter...thanks for a good product.

I have not noticed any difference in MPG however, my vehicle does seem to have more pep than before. What I do like is that I won't have to change the filter for the life of the vehicle and the ability to clean the air filter at 50,000 and continue to use it is a real economic benefit. Have a great day and continue to make high quality products.
