hi kev, i fitted my panel filter last sunday, forgot to take pics for u tho doh! anyways, took it apart again and took some photos for you.
performance wise you aint seeing no gain really, it does seem more responsive at higher rpms (4500) its nothing major tho, it does sound different when you floor it tho, sort of a deeper note, k&n is approx 2cm thick. Fitting wise its just 2 screws, lift the filter box thingy off take old filter out, put new filter in, screw it all back up and the job a guden :approve: .anyways heres the pics hope they help you decide
red circle shows 2 screws that need unscrewing, also its a good idea to remove the rubber strap further towards the air feed end to give u more access
original filter
