Hi Guys,

I know this has been done to death in the past, but im considering doing the airbox mod, and while there chucking in a K&N panel filter.

My only concern is will there be more crap getting through it into the engine, thus shortening its life span/creating potential problems in the future.

What would you do, leave as standard and do the mod?

Or stick the K&N panel filter in?

This is on a 1.9CDTI 150,
