When I spoke to someone about why I should buy a K&N instead of a paper air filter he was most helpful and I therefore bought the item.
I checked the service history of the Kia and it turned out that the air filter had NEVER been changed No wonder it was chugging up hills
It has made an amazing difference in performance and fuel economy. I will recommend it to all I know.
