So I bought a K&N (33-2119) and it doesn't fit in my 2003. I went to the K&N website to make sure I got the right part number and according to K&N they don't make a filter for the 2003 Model. I've been told that the 33-2119 fits the 2004 though. Did LR change the filter box for just the 2003 model year? | ||

why would you want one, Shane? | ||
| Shane Lesteberg (Snwbord24) Member Username: Snwbord24 Post Number: 59 Registered: 01-2004 |
Thought I'd give it a try too see if it improved mileage or power at all like it's advertised. Being cleanable/reusable is also a plus. | ||

Shane, what you will get is more fine dust past the filter, and a chance to ruin your MAF sensor if you over-oil the filter. You may be able to talk yourself into believing that you noticed the power gains and improvement in gas mileage - I was not, more than once. | ||

I've pretty much decided that but I just thought I'd find out if the 2003 4.6 filter box was different than other model years. Maybe some info that others can use besides me. | ||

Well said Peter. Exactly my experience. K&N = Snake oil. -Barry | ||

I have not had any problems with my K&N on my 03. I don't remember the part number, but it was the same filter for ealier d2's. | ||

Im glad i read this about the filters i was pretty sure i wanted to get one and now i am begining to rethink it and decide if it is really worth the money. Thanks, Nick | ||

I've run a K&N on my 95 for quite some time now and have not had any problems, than again I don't see any improvement what so ever. At first I though maybe I can feel a bit more power but then I realized it was just my imagination... | ||

Bill, if you could get the part number for the K&N on your '03 I'd like to know it. I measured my stock filter and didn't find any K&N that would fit. | ||

I just put a K&N in my 2001. I had a great increase in power, but that was probably due to the fact that the old filter had mud on it. I'm told that's bad -G-. I don't expect any kind of miracle improvement in performance, I just got sick of spending $25 a pop on paper filters when the cleanable one is $40. So if not the K&N, what do you guys recommend? The LR paper filter? | ||

I was warned away from the K&N filter because it would allow fine dust and sand in the engine. | ||

Never noticed any improvement in performance using K & N, either with my '95 Discovery or my Audi A4. And the MAF sensor on my Audi failed after a few months with the K & N. Doesn't prove that the filter clogged the MAF sensor, I know, but the coincidence is suspicious. It's probably just as good just to keep buying fresh paper filters. | ||

I was warned away from the K&N filter because it would allow fine dust and sand in the engine. As oppossed to the stock filter? The only bad thing I have heard is the potential to mess up your MAF. Any and all gains are marginal. Never had a problem with mine and it's been two years. My advice is to get it and be done with it. The construction and the ability to clean it outweighs buying new filters anually. Just don't be a moron and over oil it. EwS | ||

I've run K&Ns on a '93 RRC (for 40K kms), '94 Disco (for 20K mi.), a bunch of VWs (a whole bunch of miles/kms) and a Volvo 744T (for 160K mi out of a total of 260K). Never had any problems (MAFs or otherwise) and it makes having a clean filter a lot easier, especially on the Rovers. Now with all that said, I've never had much performance improvement on NA vehicles, but the turbos seems to like them with the VW turbo diesels seeing the most improvement (does not take much when you consider their basic HP). | ||

I think it can help more if you have a modified exhaust also. | ||

Shane, considering that you are still under factory warranty, and your scheduled maintenances are covered (which includes FREE filters when appropriate), I don't see a reason to go K&N. If the K&N causes a failure, which it may, that failure isn't going to be covered. Why screw with your warranty? I've never had anyone say OOH, I LOVE my K&N. I put one in my Disco, and I wasn't impressed. I didn't notice any performance or gas mileage improvements. | ||

Wipe your finger in the inlet tract after the filter after following someone in very dusty conditions and then see if your happy with the K&N. Then check a vehicle with OE aircleaner element. Bazzle | ||

I dunno if that's necessarily a good benchmark...if you follow anyone in a dusty trail, K&N or not, you stand the risk of sucking in some sand. That said, I had a dyno done by a buddy of mine at his shop a week, give or take, after a K&N install (which I have since removed, for other unrelated reasons) and it returned an increase of 6 horsepower over the factory BHP at the equivalent RPMs. Unfortunately I don't have the numbers in front of me, but if you I like I can dig them out and post them here. The street performance was not noticeably different, and I've heard dynos can give inconsistent readings, so take that as you will. | ||

ok ok, I'm not going with the K&N. But I'd still like to know if I have some odd size filter box. On a side note, I think I'll be ordering my snorkel kit. Went wheeling today, saw a mudpit and thought what the heck. Well, there was a huge dropoff just as you go in. The front end just dropped in and the hood was halfway underwater. The engine shut off immediately because mud and water got in the intake. Cleaned everything off, blew it dry but it didn't look like any water got in the intake or cylinders. The starter won't engage now though so it's sits at the dealer, hopefully they'll have time to look at it Monday. | ||

Shane, the 2003 & 2004 airboxes should be the same. Frequently aftermarket parts suppliers get years wrong. One thing I noticed with the stock filter v. K&N is that the stock filter stops muddy water, the K&N lets it through. This makes sense, considering the K&N is an oiled mesh designed (mainly) to stop dust, while the stock filter is paper & absorbant. Since it sounds like you are in muddy/wet conditions more than dusty ones, again, my vote is with the stock. | ||
| Shane Lesteberg (Snwbord24) Member Username: Snwbord24 Post Number: 64 Registered: 01-2004 |
Alyssa, I'll agree the stock stops muddy water. It was completely soaked yesterday with water and mud. There was some water in the intake hoses but only a few drops in the actual intake. I pulled a few plugs and there were no signs of water. | ||

K&N - all my cars, no probs, saved a bit on replacing filters and I'll throw my 2cents in that it filters better. Many baja miles with K&Ns, not as much on the disco, but on alot of Samurais and following a crew of trucks for 1 or 2k miles in Baja with 75% of it on dirt and the K&N filters more. If it screwed up a MAF, either I have been really lucky with my last 8 or so cars or someone is overoiling thier filter. Even so, just clean the MAF... |
