I currently have a K&N panel filter installed and have been toying with the idea of switching to an ITG panel filter. I have been reading on various forums with various different cars about opinions on swapping. What appeals to me is that the ITG is supposed to better at filtering the dirt from the air and being better for the engine. I cant see there being any difference in performance as i have watched loads of videos where after market filters made no more power than the standard paper filters. Has anyone switched or what are peoples views.
