Discovery and K&N
ORIGINAL: Jupiter Rover
No offense, but Don't listen to the guys saying not to use K&N. I have had mine for over 2 years and have re-oiled it twice with NO FAILED MAFS. look at that.
K&N states that their product will not harm your MAF. Just make sure not to over oil it just in case. However, someone else said that K&N also states that if the MAF does fail Due to their oil they will replace it. There have been, to my knowledge, no incidents of anyone testing the failed MAFs and finding out it was due to the oil, it is simply a myth.
One more thing. I ran a K&N for two years like I said, then I cleaned it and put back in a new paper filter for 2 weeks. I definitely noticed how the engine wasn't as "peppy". So when I threw the K&N back in it was a big improvement. The rover felt like it was suffocating those 2 weeks.

As for that air intake from Atlantic British, you risk the same thing happening with this one also. It is the oil that is the problem.
Just an FYI, take it for whatever it's worth to you:

K&N claims that if you ever take your vehicle to a service center and they blame a failed MAF sensor on the K&N filter that K&N will PAY for the repairs and will run tests on the MAF.
who knows really but it seems to be a quite hotly debated subject on these forums.

We are aware of the “urban myth†(K&N News Story) created by a few dealerships that a vehicle's MAF sensor can be contaminated by K&N filter oil. No evidence has ever been provided to support this “myth†and three years of diagnostic testing by K&N has shown that not only is this allegation not real, it is not even possible. In our opinion, it is an excuse for a dealership and/or the vehicle manufacturer to avoid a legitimate warranty repair. In the last 4 years, we have sold over 10,000,000 lifetime air filters and received only a few hundred calls from consumers who are having dealership or service provider challenges. We believe that Dealership's or service provider's real incentive may be to discourage the use of reusable products so they can sell disposable products over and over. In order to provide consumers with added comfort that they will not be placed in a bad position by an improper warranty denial, we offer our Consumer Protection Pledge.

Pledge Details
K&N warrants that a properly installed and maintained K&N product will not cause harm to any engine component and will not result in a warranty denial. We will promptly reimburse the consumer for the cost of the repair if a dealership denies warranty coverage as a result of a K&N product. In order to receive reimbursement, a consumer must provide the following:
[ol][*]
A written statement or repair order from the dealership in which the dealership blames the problem or warranty denial on a K&N product. [*]
A written request to the dealership to send the broken part directly to K&N at K&N’s expense. We will need the evidence.[*]
Your cooperation in helping us pursue our claim for reimbursement from the dealership. [/ol]
K&N will then contact the dealership and insist they present evidence to support their allegation or reimburse K&N for the cost of the repair. We strive to exceed consumer expectations. Customer service can be reached at 1-800-858-3333.

I thought I didn't know what I was talking about........ Thanks unstable, I was too lazy to look it up. Even darover states that the people in his club who all had bad MAFs were not even running K&N's.... Millions of people use K&N, it wouldn't be such a popular product if they killed MAFs.
You can run a K&N on older non Bosch system but not on ours.
As a service manager we used to see the come in quite often and Rover had to finally replacing the MAF's under warranty.
I have been envolved with 3 people who's MAF's failed, their shop sent the MAF's to K&N and no one of them ever got a free replacement.
Bottom line, if you have an extra $220 plus in your pocket go for it, if you are smart you'll spend it on gas instead and not try and disprove a proven fact.

based on what Darover said, it probably makes more sense to stick with the traditional paper filter anyhow. Who drives most of the time on highways anyways? If the K&N gave appreciable MPG on the highway and you're going for a long trip and have faith that K&N would honor their guarantee...toss in the K&N, reap the rewards of better MPG and swap it out later.
I haven't had any personal experiences with K&N, but it's my thought that the air filters didn't get a bad rap on the Rovers for no reason. Disco Mike always recommends the HP-3001 K&N Oil Filter...but never the air filter. There has to be some kind of foundation to these claims that it screws up the Rover MAF sensor (or maybe something else).
It is important to have some intelligent debate about these things and get the information out there so people can chew on it a little and make a decision.

Well said Unstable. If the K&N would at least improve m.p.g, it would be acceptable to go ahead and gamble, knowing that by getting better m.p.g you are actually saving money and that if people actually end up being right about the MAF thing, you just end up spending for a new maf what you have saved in gas. But I assure you that it isn't so. And believe me that I even tried to be easier on the pedal and did everything in my power to make the K&N worthwhile in gas mileage. But it just didn't happen. I really did lose mileage.
With the price of gas recently, I want to do everything that I can to make my Disco as fuel efficient as possible, and that meant re-installing the paper filter. That way I get better m.p.g, and don't have to worry about the filter killing my maf. doesn't mean that the MAF is safe, it just means that if it goes I won't have to wonder if all the hype is right.
I do however admit that if the K&N would have help my m.p.g, it would still be in there, simply because of the logic explained above.

For what it is worth, I have seen 3 Disco's (series 2)on E-bay with the check engine light on and the disclaimer that they would idle fine, but stuble all over when trying to pull off.. 2 of them had the cone style "cold air" intakes, and just a drop in K&N. I sent messages to all 3 telling of the MAF problems I had heard of. 2 of them replaced the MAF's and were fixed. One did not respond. The 2 that responded were very grateful... I see a broke Disco, I have to fix it.
Point being, I have seen 2 cases where the MAF's went out. Even if you have a 50/50 shot at it working, why risk? That is my theory.

My decision. I'm putting a new air filter in, but standard. Thanks guys. I keep looking on the sites, though your telling me 250.00, it says MAF 250.00 is for series II. series one is 950.00. and about 1250.00 for older than that. I'll read on the fourms and take advice on other small things to do to help it out. Thanks for everything.
