santalars Posted April 1, 2009 Share Posted April 1, 2009 I will have to clean my K&N air filter soon. I know that there are service kits consisting of cleaner and oil. However, they are hard to get in Ireland and I'm thinking of alternatives. I'm sure that for cleaning break cleaner will do the job, but I don't know what kind of oil I should use for it. Can I used WD40, which would be convenient? Quote Link to comment Share on other sites More sharing options...
steve_d Posted April 1, 2009 Share Posted April 1, 2009 I believe the oil in WD-40 is lanolin and very light so I would not expect it to work. will someone like this on ebay not ship it to NI. http://cgi.ebay.co.uk/K-N-Air-Filter-Oil-S...%3A2|240%3A1318 Steve Quote Link to comment Share on other sites More sharing options...
Godlykepower Posted April 1, 2009 Share Posted April 1, 2009 If I were you, I would go through the hassle of trying to get the genuine K&N cleaner kit. Get the real thing, have it shipped over, & pay whatever you have to...... ......it lasts for years, and you wont have to go through the agro of doing it all over again for a very long time. At least then you will have the peace of mind that you have not had to bodge it. Surely the P+P to the Emerald Isle wont be THAT much from someone over here? My 2p.

BigMac1 Posted April 1, 2009 Share Posted April 1, 2009 I serviced my old mans C2 over the weekend. He fitted a K&N some time last year. We used 'this' kit to clean and oil the air filter. For the cost and the lifespan of the filter if serviced as it should, it doesn't work out that expensive, and better for the environment.

q-rover Posted April 1, 2009 Share Posted April 1, 2009 Las time I serviced a K+N filter, I removed and replaced it with a standard paper element. Took about 1 minute and no mess. Quote Link to comment Share on other sites More sharing options...
pat_pending Posted April 1, 2009 Share Posted April 1, 2009 Clean it with Gunk or Jizer (water soluble) degreaser, wash out with plenty of water, dry in the airing cupboard and re-oil with auto box fluid. Worked ok on the the bike filters for years, and cheap/readily available. Quote Link to comment Share on other sites More sharing options...
santalars Posted April 1, 2009 Author Share Posted April 1, 2009 Thanks all. Will have a sleep over it. Probably I might go with the real thing. I just thought that it's probably not that important what you use to do the job, and as stated by pat it might not be. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted April 1, 2009 Share Posted April 1, 2009 I'd remove it and replace it with a paper one that actually filters things out. Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted April 2, 2009 Share Posted April 2, 2009 ^^^^ Wot he says K&Ns and 4x4s are a poor mix, esp if your off road at all with dust dirt. OK for a chav wagon outside Mackydees, but for 4x4ing the filtration offerred is horrendously poor, throw it away and use a std paper filter Nige Quote Link to comment Share on other sites More sharing options...
santalars Posted April 2, 2009 Author Share Posted April 2, 2009 As far as I know K&N filters are woldwide used for quarry and construction plant. They must have done a hell of a good job to convince them all to buy sh8. Or is the 300 tdi more sensitive? Quote Link to comment Share on other sites More sharing options...

Or is the 300 tdi more sensitive? Good one, April 1st and all that. Seriously, no earth moving gear anywhere in the world uses a K&N, they wouldn't last a day. Construction and ag gear worldwide use either Donaldson, Cummins/Fleetguard or Mann-Hummel elements. If I find isuzurover I'll point him this way. Ben is a filter research engineer, he's consulted to the biggest filter companies in the world (the three I listed) and passionately dislikes K&N's. They are really, really old school, the only thing they have going for them is their flow rates (as the holes are so big) and pretty much only keep rocks out. We did some tests here using very sensitive lab equipment and cellulose fibre (paper) and K&N's. I supplied most of the filters, isuzurover did the tests. With the first lot of tests, Ben had to check that the small particle size being fed into the filter it was being fed in the correct side, so much was registering upstream ! They are good for a clean race track, and nothing else. Quote Link to comment Share on other sites More sharing options...
LandyManLuke Posted April 2, 2009 Share Posted April 2, 2009 The info/link in this post should be archived, nowt like some facts* to detract from a good argument!! *especially when numbers are presented as pretty pictures Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted April 2, 2009 Share Posted April 2, 2009 I have some filter cleaner and a can of oil .... And a 300Tdi filter that don't work and never did whether oiled or not. But maybe in Oireland a K&N will be ok as it rains all the time. Seriously, you might as well have no filter at all. The thought of a K&N on earthmoving equipment makes me shudder. remember the filter has a million-mile warranty. This doesn't unfortunately extend to your engine Quote Link to comment Share on other sites More sharing options...
santalars Posted April 2, 2009 Author Share Posted April 2, 2009 I think I better shut up and get a paper filter. Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted April 2, 2009 Share Posted April 2, 2009 A lot easier to just buy a new paper filter every X miles than to faff with cleaning and re-using one. Quote Link to comment Share on other sites More sharing options...
sgnas Posted April 2, 2009 Share Posted April 2, 2009 Pretty pictures are nice but one sentence sums it all up. "Compared to the AC, the K&N “plugged up” nearly 3 times faster, passed 18 times more dirt and captured 37% less dirt." Quote Link to comment Share on other sites More sharing options...

Don't get hung up on the brand, read it as "Compared to the cellulose fibre (paper) the oiled cotton gauze “plugged up” nearly 3 times faster, passed 18 times more dirt and captured 37% less dirt."

santalars Posted April 3, 2009 Author Share Posted April 3, 2009 Just for your interest, this is K&N's reply as I confronted them with what has been said here: "Hello Thank you for your enquiry. The world is littered with doom and gloom forums to the extent that one would avoid purchasing anything if one took notice of all the reasons not to buy. K&N have been manufacturing air filters for forty years. It is worth noting that our product was originally developed for off road desert racing, i.e. the Baja 1000. Today we produce for just about every type of internal combustion engine from F1 to the very latest models of car, motor cycle, ATV, watercraft etc. etc. Please see the link below but of course the choice is yours whether it’s a bottle of milk or a new house. http://www.knfilters.com/air_filter_testing.htm Regards Don Marshall Technical Assistance K&N FILTERS (EUROPE) LTD" Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted April 3, 2009 Share Posted April 3, 2009 When has racing ever been proof that a product (especially one who sponsors the team) is any good? F1 engines are not designed with a long life in mind, a lot of racers run with no air filter at all. If a bit of oily cotton was that good it would come from the factory with it in, I can't believe it's any more expensive to make cotton than paper filter media. Best fit a HiClone, fuel magnet, HHO generator and some slick50 while you're there Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted April 3, 2009 Share Posted April 3, 2009 These Guys absolutely swear by them as well 'whikid' and 'asdabiz' So there you go, with the above and the technical e-mail back from K&N what do we know Nige Quote Link to comment Share on other sites More sharing options...
santalars Posted April 3, 2009 Author Share Posted April 3, 2009 Yeah, I learned the lesson. Still I'm very surprised that there are no real pro K&N voices here. Quote Link to comment Share on other sites More sharing options...
Godlykepower Posted April 3, 2009 Share Posted April 3, 2009 OK, I will be the minority "for" voice then! I have not bothered replying in favour of K&N in this thread, as this subject can end up going round in circles for ages. Also, I have a lot of respect for the wealth of knowledge of several of the members who HAVE commented about the negatives regarding these filters. They know what they are talking about, and I dont doubt them, or their opinion. However, I swear by K&N filters, having used them for years, in a multitude of vehicles - mainly sports cars, and lately obviously in my Defender. As I am not really into off-roading per se, and only use my vehicle for predominantly road use, with mild greenlaning when I can, I am not that bothered about all the figures relating to amounts of dust allowed through a K&N, as I dont get into dusty situations that often. Saying that, and with my respect for this forums' members opinions in mind, I always carry a spare genuine Land Rover filter that can be changed at a moments notice. This is primarily for Trans-Africa, where I will have an extended period of Sahara driving to contend with. Thats just my little voice in favour of K&N, and I dont want to start a debate or argument, but I really do like them. Martin Quote Link to comment Share on other sites More sharing options...
nicks90 Posted April 3, 2009 Share Posted April 3, 2009 i have a 'pro comment'. as a very temporary measure it was handy to have one lying around in the garage when we did a tdi swap on a mates 110 - as we ran out of time to build the airbox and brackets in the engine bay and just slapped the K&N filter to a bit of pipe cable tied to the inner wing! That stayed on for .... oooooh, must have been a whole week before we got the willies about it killing his new engine and we did the brackets the following day!
