I love K&N Air Filters. I use them all the time...excellent increase in horsepower (engine responsiveness) and gas mileage. I was just concerned with the pricing on the K&N Home website, it's very expensive compared to another website I had found. Still a great product though.

Arrived on time, perfect condition, and installed next day, works great

Produit excellent comme toujours avec K&N Livré en 48h comme convenu même bien plus rapide que bien des sites de vente en ligne français. Ce que je regrette, c’est aucunes solution d’admission directe pour mon véhicule (audi a4 B7 2.0 TDI)
