Lo all, Went to enquire about a K&N air filter for my 52 plate 2.2DTI and was informed by the chap behind the counter that there was no real gain from fitting one because there is already sufficient straight line air flow to the turbo.
OK, is there any point to buying one apart from it will be the only one you need ever buy
Was the guy talking tonk or is there any real world gain for dropping approx forty quid on one of these?
