Parte K&N correspondiendo con el filtro de aire STP SA10234

Excellent product and fantastic service and delivery. I would be very happy to use the service again. J Saunders

This K&N air filter has turned what was a sluggish and juddery 1.5 diesel Qashqai into something altogether more smooth and responsive. Gears 1 thru 3 are so much more alive and much quicker to pickup and move. What was a sceptical purchase is now a recommended purchase.

Noticeable rpm increase. Feel a few more ponies. Pays itself off in 50K miles or less. Never can go wrong with a K&N. Been a fan and user of K&N filters for a long time.

Purchased a 2015 Infiniti QX50 w/36k mi. in May 2018. I have used the K&N Air Filters on 2 previous recent vehicles. I decided a few months later when I found out this QX50 actually had 2 air filters I should do what I already new better about. I was surprised after I ordered a pair of 33-5014 K&N replacement air filters and went to work to install the new filters. The then current air filters were probably factory original and never ever replaced, black as black on the input air side. After installing the new pair of 33-5014 K&N replacement air filters and driving the car I was literally blown away with the extra engine power and the healthy robust tuned exhaust. Thanks for making these filters available.

It's work great in my Infiniti Q50S.

I reset my average MPG display when I installed these a few weeks ago, and I'm tracking about 1MPG better than I have since I bought the car. I'm very pleased with them.
