Having fitted a new 60mm TB, I decided it was time to clean the air filter too. I'm amazed at the effect it's had! Clean filter and a clean (and now enlarged) throttle body has made a huge improvement to throttle response and low rev pull. The car's become so much more driveable! Definitely recommend it if you haven't cleaned the filter out in a while..

Yeh definitely, used to clean my K&N regularly

You're recommended to clean it every 10k miles or 12 months regardless. Quite a few people don't realise that and stick them on and think that's the end of it lol
