I've used three conical K&N filters on my previous cars and loved the products and performance when paired with a cold air intake. I recently bought a new 2015 vw GTI and decided to use a panel filter with stock air box while more options for cold air intakes become available. As usual, the filter had great craftsmanship and slight increases in throttle response and gas mileage. I'm confident saying that I'll be using a K&N filter in every car I will own. Keep up the great customer service, R&D, and products!
