I have purchased K&N parts for several cars, ranging from complete intake systems to replacement air filters. All have been of high quality and no problems encountered. The 33-2418, a replacement air filter, was purchased recently to put into a brand new Volvo V60 Turbo 6 to improve intake flow. It arrived promptly and installation is very simple but does require a special driver tip for the screws holding down the air box cover (Volvo bad, not K&N). Although the filter does not emit that beautiful wail of a complete K&N intake system at full song, I will at least have a little freer intake flow compared to the stock filter. If K&N comes up with an intake system for the T6, I will be first in line.

I tried the kit 57S-4000 with exchange filter from K&N with the new lid for the air box. Just looking at the product and thinking about the idea of putting in a bigger filter by making a new bigger lid of the air filter is in my world is brilliant. The work putting it on was super easy and with good fittings, and with an easy manual. The performance was noticeably better through all the revs. And the best part of all was that the fuel consumption went down below the car manufacturer’s data. This kit cost a lot, but it really works and it will save you fuel, and by the time it will actually pay it self off. I recommend this K&N kit to all Volvo V40 D2 owners.

Arrived as promised and fit perfectly. Site was easy to use and ensured right fitment for all models of Volvo S 80. I tried first ordering thru Amazon and they only listed one filter for all models which was not correct. Thanks.
