Does anyone here run K&N air filters? If so, have you had any trouble with the oil from the filter getting on the MAF sensor and causing trouble? I'm considering a K&N, but I sure don't need any extra problems. Just wanted your opinions.Thanks. Don

No problems so far for me, for the mass air. I have no idea about their performance claims, I just like the fact that I can completely clean it whenever I need too, and don't have to purchase a new one.I'm very careful whenever I oil the filter. Allowing just enough to to have the cotton completely red in color, without much excess. Stewart

K&N's are very good filters. You won't have to worry about the oil getting on anything until you are ready to clean and re-oil it. At that point, just follow the directions and make sure it is 'dry' before you reinstall it.I've had K&N's in all my mustangs and never had a problem. ------------------

Love mine. No problems. You'd have to MAJORLY over-oil it to have any problems like that.Stupid is as stupid does, my mama always said.

I have a K&N in my '77. Good filter. Haven't had to clean it quite yet though.I'm considering putting one in the '99, but is that whole warranty crap true? I read in the owner's manual for the car that if an oil-based (or however it was worded) air filter is installed in the car, the warranty is voided out. ------------------

I would just put one (II good) and then take it out when you have it in for service, or, god forbid, the car pukes on you. I have had mine in for a little bit and will find out wednesday if the K&N, densecharger, and MAF post removal makes any difference in 1/4 mile times. I have heard nothing but good stuff about it, though alex says motorcraft filters work just fine and doesn't bother with the K&N's.

That Densecharger has been getting RAVE reviews from Bullitt owners. They are absolutely in love with the thing.Let me know how your times go after the install. Mike

You will lose horsepower with a Densecharger. The 90 degree bend just in front of the MAF meter kills the calibration. You need a recalibrated MAF meter for it to do any good.------------------

The densecharger is a Cold Air Induction system that is designed to allow you to change the length and direction of the pipe insode the wheel well. You can find information on the densecharger system herehttp://www.densecharger.com/ There is a long thread over at the Bullittclub that goes into some pretty deep technical details on it. http://www.bullittclub.com/phpBB/viewtopic.php?topic=413&forum=2&32 Mike

I was having problems with my densecharger at first (check engine light coming on, code reading engine too rich) not to mention a 15.8 quarter mile from a 15.3, but I came up with a replacement for the maf screen that densechager said not to put in. I just put some screen that matched the original in between the maf and densecharger, and it has worked like a charm so far. I even removed the maf post. I think that just as long as part of the air flow is directed by the screen to the sensor, things are alright. No dummy lights and going on 300 miles. Let's keep the fingers crossed, and we shall what the clock at the strip says..........

I have a MAC cold air system with a K&N. No problems. (You can hear the air flow more than stock.) My buddy has a '01 GT and hasn't and any problems. The first I heard about this was in this months Mustang Club of America news letter. Don't know about performance, but I like the K&N.------------------

I'm "stupid is As Stupid does"
I never new about the over oiling situation and did over oil my K&N when I was rushing to clean it and reinstall it on my truck. I had it for 3 yrs before that with no issues what so ever. I still have it on the truck and the 01 and 68. As for the price....I think the regular replacement paper filter is $20 or so. The K&N was $44 and I have had it on for over 4yrs now. I think it already paid for itself. ------------------

There is a tread on the Mustangworld.com website with people having problems with the oil getting on the MAF sensor causing stalling and erratic idle. I have used on on my 93GT for several years and 150,00 muiles and never had a problem with it. It is funny how you start hearing about it on the 99 up cars.

Yeah, when you clean the filter (with the special K&N cleaning kit), you also must oil it - the oil is what does a lot of the 'dirt-trapping' and is what makes the filter red in color. Without it, you have a worthless filter (for the most part..).I bought my K&N Fuel Injection Performance kit a year ago, and I really noticed a big difference in power! The mid-high RPMs were really putting me back in my seat. And even though it didn't need it, I just cleaned my filter recently, after about a year of driving (approx 18,000 miles). K&N claims 50,000 miles before cleaning is needed, but......  One cannot stress enough, though, to not over-oil it. That's what will screw your MAF up. As long as you don't do that, you're golden!  ~Brian ------------------

Not to change the brand names, but I put a Holley ProCharger filter on the '01 Gt, this is only because I won it at our local cruise in, Holley was the sponsor that night. But, being my wifes daily driver, her mileage went up over 1 mile per gallon. Holley advertises their filter as being better than the K&N. Then again, her stock filter was dirty as hell. Mike

If you can, go for a Conical K&N
When I took my bros '89 to the dyno a week and a half ago (with one of those big fans at the front of the car to simulate the car "moving") we did a total of four runs.The 3rd and 4th runs were the "meat and potatoes" so to speak but what was interesting was that on the THIRD run, we kept the K&N in the factory box and got our HP/TQ numbers.
On the FOURTH run, we took the air box out entirely leaving the mass air meter exposed and gained 12hp and 10 lb/ft of torque!!! So if you can (I dont know if the airbox on the '94-up stangs is the same as the Fox-bodies) buy a conical, itll be much less restrictive than the stock box and it will STILL be a K&N
have a good one  ------------------

Dan, anytime you remove the air filter, you're going to improve your H/P numbers, so that doesn't really prove that a conical is better than a panel. Plus, there is the argument that a conical filter will pull in hot air heated by the engine, and that systems like underbumper CAI systems improve the density of the air entering the manifold. Densecharger supposedly has done a study proving their system lowers the temperature of air entering the intake manifold. Stewart

I have the MAC cold air kit on my 01 vert as well, but I need to get the right K & N filter to fit it. Does anyone know the part number? The last time the stupid parts store ordered the wrong one. *rolleyes* You help is greatly appreciated.
