K&N air filter (in airbox) Are they worth it?
Views on the in-airbox K&N's, please:
Are they worth it?

They will last the lifetime of the car, so you'll never need replace it. Cost effective? Depends on how often you change the car
Performance? slightly better breathing but you're not going to make 50bhp I have an airbox one & an open induction, love them both |

no
for one thing cleaning them is a pain in the bum, then you have to re-oil them so it's just easier (and actually cheaper) to buy a normal one every year. The airbox ones make no difference in performance either and if it's a diesel it will possibly contaminate your £160 MAF Last edited by mystabe; 18th October 2018 at 19:28.. |

Banana has had her flat K&N filter for the last 6 years.

Had a K&N in my diesel ZTT’s air box for nearly 7 years now with no effect on the MAF whatsoever. It’s when people over oil them that causes issues.
Cleaning is easy, do mine once a year. It’s the first job I do when servicing, gives it chance to dry, just give it a blow with the compressor to make sure before I oil it. So, over the 7 years I’d have used 7 genuine standard air filters at around £12 each......£84 The K&N cost me £39.99 and I’ve used half of my second cleaning kit at £10 each.......£15. So, in seven years, it’s cost me £55 with the K&N opposed to £84 for gen standard filters You also get a couple of cool stickers with them too

So you save £5 a year for no measurable benefit?
and you still have to mess about with it rather than just drop a new one in.... Obviously the stickers are cool! Cool kids have Pipercross ones but K&N are old skool kool. All nonsense if you have a standard airbox Last edited by mystabe; 18th October 2018 at 21:44.. |

Had a few performance filters over the years and to be honest, I'm sure that any performance gain was all in my head. To actually feel a difference your going to need and extra 10 bhp minimum and that just isn't going to happen on a car in standard tune. For a modified engine they could be worthwhile.
Really can't be bothered anymore especially on my diesel, rather have the superior filtration of a standard filter even if it does cost more in the long run.

why would we judge any real world performance benefit in "Peak" bhp figures ?
from my experience - the Car breathes a lot better with a K&N panel filter jobs a Good Un throttle response IS better - maybe not Huge Measurable Gains - but Noticeable enough to be worth fitting (IMO) Sounds Good too Paul. |
