It could be a cost effective depending on price but probably only go through 4 filters in the ownership of the car if that.
I'd put money on it doing next to nothing! Why don't you buy one and on your dyno day do the last run with the k&n filter that'll give you your answer.
I'd love to be proved wrong because I'd buy one lol.

Thanks mate, good gen. I think I may well try your suggestion and see if it gives any more on the RR. I've felt a slight difference on petrols I've fitted it too but as you have eluded to, may not be as effective on a diesel. Ta
