Hi all,

Has anybody any thoughts on performance air filter replacements?
Are they worth the money? Would you notice any difference?
Or shall i just stick to a normal air filter replacement?

Thanks
 
on its own you'll see no difference at all, 1-2bhp tops which you wont ever be able to notice. the only plus side is its washable but by time you've got the proper oil for it you may as well just buy a new paper filter.
 
Ive got a k&n on my 200tdi rrc and i put it in solely for the fact it can be reused over and over again. The oil and cleaning solution kit is about £20 i think and is enough for a few cleans. Overall id say get one as they are a superior filter to oem and you get some nice stickers in the kit. Not as cheap to use as fire starters tho.
 
Ah've got one in me bus (200tdi Def) and ah like it. Ah sometimes stick one of them paper ones in when ah'm cleanin' mine and the engine sounds totally different. Ah only got one 'cos me local indy had one goin' cheap;)
 
Never had one on a disco but had one on another car and there are cheaper ways of cleaning then but tbh if your not converting anything else I wouldn't worry although they can aid fuel consumption if they are kept clean

hello local member:)

as for the k&N there are reports of them letting fine dust past and causing engine damage they are expensive as sad they are cleanable but the oil cost more than a new paper type filter and they cannot be used if you have a car with a MAF sensor (v8, edc 300s, and td5) as the oil on the filter covers the eliment in the MAF sensors

what about other makes such as green cotton, pipercross etc do they have a similar effect on MAFS
 
From experience they are all pretty much the same (Iused to tune Volvo's as a side line) although they ave to wkr hard an engine uses 10,000 litres of air for every litre of fuel which is a lot on any disco.

Hi martinhollings good to see there is someone else in the area on here
 
there are filters on the market that haven't got filter oil on them. I will do a search later and post what i find. They have had to do this because of the problems with fouling the maf
