Author Message   Norm Posted on Wednesday, September 18, 2002 - 12:00 am:    I need to replace my air filter anyone running K&N without problems, any improvements... Norm 97 Disco   Blake Luse (Muddyrover) Posted on Wednesday, September 18, 2002 - 12:02 am:    people say don't do it the oil messes up the mass air flow sensor by clogging it and it lets bigger dirt particles in when off road or in a dusty enviroment there was another thread like this and it made me go and buy a 3 dollar one from a parts store and sell mine on ebay. the gains don't out weigh the risks   Larry Nicklas (Larryn) Posted on Wednesday, September 18, 2002 - 03:31 pm:    Hi Norm, Just a (slightly) related/unrelated story. Last year I replaced my stock filter on my '02 bmw 330i with the K&N. About 2 months later, I developed bad hesitation problems. I made an appointment to have the car checked, as it was fairly unusable. I did place the stock filter back in (just in case). It turned out to be the throttle body was fouled with oil, and the dealer wanted to know specifically, if I used a K&N.... So, it might have just been my filter, but it must have been waaay over-oiled @ the factory. Of course, with a Disco compared to the bimmer, your "milage" may vary... BTW, just got a '01 DII SE7 on Monday! So, first post, and Hi everyone!   bryan Posted on Wednesday, September 18, 2002 - 03:49 pm:    I had the same hesitation problem as Larry with my 95 DI and my MAF finally gave up a few weeks ago. A mechanic who worked on my rig in July told me my MAF was coated with oil and that there was far to much oil on my K&N (straigh out of the box). He suggested I get rid of it before it caused me problems down the line.......I changed back to paper in August, but the damage had already been done. Expensive lesson!!!   Al P Posted on Wednesday, September 18, 2002 - 04:03 pm:    I have a 92 BMW 325I, with the K&N filter for about 20k miles. 96 Disco with K&N filter with about 4k miles, no hesitation or any other problems. Its, tough for a company to last this long, if there were some issues. Bottom Line, If you don't feel comfortable don't do it.   ken Posted on Wednesday, September 18, 2002 - 04:46 pm:    "Its, tough for a company to last this long, if there were some issues.

Landrover's been making oil leaking cars for quit some time; but people still buy them. ken   p m Posted on Wednesday, September 18, 2002 - 04:48 pm:    Norm, I've put a K&N in my 96 Disco for the only reason that this was the only air filter i could buy on a weekend. about 50kmi later - the engine runs all right, but the top of the air cleaner housing is coated with a very fine dust, and so is the MAF intake. Cleaning and re-oiling the K&N is a toss-up with the Disco, because you can indeed ruin the MAF sensor. As far as K&N torque/horsepower gain claims go, there were none on any of the vehicles I had them on (4.0 LR V8, 5.9 AMC V8, 2.5 Jeep I4, 4.0 Ford V6, what else?). None. One reason to have it on the big jeep was that K&N filters are reportedly water-proof, the surface tension of the oiled mesh keeps the water out. Is it enough to overcome the engine vacuum? don't know, and don't want to find out. so, while I am not sure that K&N really belong in the Kyle's window, I'm not buying any more. peter   Norm Posted on Wednesday, September 18, 2002 - 11:40 pm:    Thanks for the great responses I heard some issues regarding oil on the MAF sensor. I also have a 91 BMW 525i with a K&N and no problems, you must however not to over do it when reoiling the filter. At this point its a toss up, I have a stick in the BMW and there is some gain and this great gasp of air when you floor it. Thanks again Norm 97 Disco   Phillip Perkinson (R0ver4x4) Posted on Thursday, September 19, 2002 - 04:35 pm:    well in terms of those kinda help yopur motor breath get more power milage air filters what do you guys roccomend?   Bentvictor Posted on Saturday, September 21, 2002 - 12:17 am:    Heck, I just bought one. I thought that I was doing my Rover a favor. Should I trash it now (ouch) or just trash it when it needs to be re-oiled? Thanks...   muskyman Posted on Saturday, September 21, 2002 - 12:31 am:    BMW has had a void warrenty situation with K&N filters for years. the MAF/hot wire failures are well known and guys in the hot rod world pull them out and clean the hot wire's on a regualr basis to prevent the wire from getting fried. adding this extra maintenance to a allready high maintenance rig just dosent make sence. and if you lose some filtration as well then its really a stupid idea.
