Simply the best. I don't have many performance upgrade options at my disposal for my 2013 Lexus ES300h. K&N intakes and filters have always been a staple of my previous rides. This air filter boosted my mpg's by 2 after only the first tank of gas. Just wish they would have sent me a sticker with black print for a white car instead of the white print that I got.

Filters were easy to replace, no problems.
