Simple question, has anybody bothered to do this ?
The K&N website says clean one after 50k miles or 25k if its been in dusty conditions. I know mines is nowhere near that, but with my remap coming up I want everything to be in tip top condition, just wondering if this is going to be a major contributor to performance and whether I should make the effort.
The cleaning kits are about £10-12 from various sources vs £35 for a new filter.
