K&N 33-2451 Replacement Air Filter,Heather Red

I have bought these style of filters for 3 cars now - a very nippy Audi TT, a Nissan Qashqai and now an elderly i40 estate. Although it obviously doesn't give any noticeable increase in acceleration, it does seem to get me about 5% increase on MPG. What's more noticeable in all the cars is the low end power, the smoothness of the drives and how much less I need to change down a gear when slowing through village roads (I live in a rural area). It's just a *nicer* drive even on the 1.7 diesel with 190k miles (305k km!) on it. Plus not cleaning vs replacing seems slightly better for the environment.

Million mile warranty. Never needs changed for the price of 2 or 3 standard ones. Get the re-oiling solution as well, had difficulty finding it locally near Glasgow, Scotland.

Very good item delivered quickly at a good price.

Fit's perfect does what it says on the box. thanks
