Is it worth fitting a K&N or equivelant to my MK2.5 1.8 petrol 58 plate?[/quote]
This will be simple terms as I'm not a techy guy lol
I have a direct replacement K&N Panel filter fitted to my 2.0TDCI '09 reg, I personally do feel that it does give a little (very little) horsepower difference and is a bit quicker on acceleration pick up, having said that this could be a placebo effect of knowing it is there.
Cost saving wise....the panel filter costs about £45 'ish and I have had mine for 2 years now and the car has had 2 services which the Ford Dealer has knocked of about £20 each time therefore I have already broken-even so happy.
