Has anyone fitted a K&N air filter, worth doing?
I see they are approx. £60 so just wanted to see if it's worth it.

I have and couldn’t find anything hence the question here.Have a google, if you like your engine do not go there.
I did that and this was the first thing that came upTry googling k+n air filter oil on maf sensor, put same words into youtube and get reading.

There's no doubt that the K&N allows more air though than a paper filter, but this is at the expense of dirt retention, which is the only reason an air filter is there to start with.If you look hard there's people on YouTube testing particle retention, dyno results etc
As a mature boy-racer, lets call me a road-racer, the principle of a K&N filter are right up my streer, however Lynall nailed it by citing the damage filter-oil can do to the MAF sensor. Simply put the old oiled-filter design works great on old carburetted or "flapper" Air Flow Meter set ups, but it has no place on a hotwire / MAF setup. On any modern motor where I do still want a "sports filter", I go for pipercross these days, however, the M47 engine design really doesn't need a sports filter. I'm not just saying that as I'm middleaged now, and could thereforebe perceived as having turned into a fuddy-duddy...Try googling k+n air filter oil on maf sensor, put same words into youtube and get reading.
I believe the OP was talking about a K&N Filter that drops in in place of the stock filter, rather than one of those universal cone type filters, so it would still suck in colder air from outside the engine bay.There's a reason the standard setup sucks air from outside the engine bay - heat. Better to get good quality filter that fits the standard housing.
