Panel air filters

[marc]

I've got a bit of spare cash at the mo and wouldn't mind upgrading my air filter. Has anyone fitted an after market panel filter, if so which one 's the best and is their any noticeable difference in performance afterwards. Thanks inadvance of any information recieved.

A friend of mine rr'd a car with the original panel filter and a k&N panel filter and there was absolutely no difference between the 2 results so I would say they are a waste of money!
