Great Product Made good extra performance for my diesel Kia Sportage, and shipped for free to the Philippines in just a few days.

This is the second vehicle I have fitted a K&N Filter to. For the mileage I do and the length of time I run a car before changing its a fit and forget action. On the previous car , I had travelled over 60000 miles before exchanging, but out of curiosity checked the filter before letting it go. The filter was still relatively clear. I have fitted the two filters to turbo diesel engines, and the increased performance, does 'throw you into the back of the seat it does produce the opportunity of saving fuel. You can change up sooner and remain in the higher gear longer. - That's all I wanted, especially when towing the caravan around Wales and Scotland.
