    Default K&N oil filter and air filter ???

    Has anyone ever used a K&N oil or air filter on there bx's if so I have a bx 2360 and was wondering what the part #'s were? I have used their oil and air filters for years on many autos and trucks the thing I like about air filters you wash them out ,reoil and put back in till next time to clean.

    The oil filters I'm not sure about.
    On other diesel forums, I've seen it strongly recommended against using K&N air filters. Especially for turbo diesels. Supposedly the flow is a little too unrestricted, letting in bigger particles than other filters. The other argument is that the repeated washing/oiling of the gauze opens them up over time to let even more particles in. A lot of folks think that the filtration is better with paper. Then just chuck them when they're done.
    I heard this from several folks after I'd already installed a K&N kit on my Ford Powerstroke. So I simply kept the hardware in place and replaced the filter element with a Donaldson water resistant model.
    But if the other forum is any indication, they'll be plenty of point/counterpoint here just like there is on the Oil & Lubricant forum here.

    Glad you brought that up. I had been considering putting a K&N air filter on my 184-4 Massey diesel. Thanks for the info.

    A Paper filter is far superior in protection.

    I have the air filters or a copy on all my vehicles since about 2000. No issues but on my tractors I just use the paper filters. Just too dusty for anything else in my opinion.

    I would use WIX oil filters as they are just as good as K&N oil filters. Also, it looks like K&N does not make an air filter for your tractor model. I looked up your model tractor on WIX website which is part number 46449, crossed it on K&N site, there is no available K&N part number.

    FYI - I use K&N air filters in my car, New Holland Boomer 3040 tractor and Scag Tiger Cat ZTR. Never had any issues with the filters. The car filters have to be re-oiled, however, K&N makes two newer filters for the Donaldson airboxes which are hybrid filters that just need to be washed and not re-oiled. I look at it simply as if these air filters did not work, then K&N would not be able to sell the filters and stay in business. As for turbo diesel engines, I have no idea about that as I only used this K&N filter in a naturally aspirated diesel engine.

    I had a K&N air filter on my previous truck. It made a noticeable seat of the pants improvement in power (despite people saying it woouldn't). However I routinely found a light coating of dust downstream of the filter, in the intake tube. Interestingly, the oil analysis never indicated an elevated amount of silicone, which would be the primary indicator of a failing air filter, so the dust was not really affecting anything. I was also prone to over oiling the gauze, so I had to clean the MAF sensor often. But that truck went 120K miles with the K&N in place for nearly the whole time, without any engine related issues.

    I don't have a K&N air filter for my current ride, but I do routinely use the K&N oil filters. The canisters are made of a heavier gauge metal and they have a nut on the bottom for easy removal. Its nice because the GM LS motors have the filter tucked up near the oil pan, making access tight. I have no personal data on the filtering capability, but I would bet its better that the cheaper units and at least as good as the "extended mileage" filters.

    I too read years ago about dusting issues with K&N filters. I have never used their products and here is my reasoning.

    What is it that makes K&N better than Ford or JD air or oil filters? I have no idea.

    Have I ever heard of a problem with Ford or JD air or oil filters. No.

    Have I had a problem with these filters. No.

    Have I heard of issues with K&N air filters? Yes.

    WHY do I want to spend time oiling a filter?

    Why change?

    For oil filters, I have been using JD ones for years on both the tractor and truck. The truck filters are Fleetguard and look/feel just like the Ford and other brand oil filters I have used with the exception of Mobil. I have never seen a difference in a UOA that tells me one filter is better than the other.

    Oddly enough but good for me, my JD dealer stocks oil and fuel filters for my Ford. If I do not have what I need on the shelf, I can send them an email on a Monday and get the filters by Tuesday or Wednesday. The price will be cheaper than what I pay at the local parts store IF the local stores have the filters in stock. So many times I have had to go to multiple stores to get a oil filter.

    I have not changed the air filters in a while in both truck and tractor. The air restriction gauge has not changed so I have just left the filters alone. No difference in performance or UOAs.

    Later,
    Dan

    I installed a K&N air filter in my 89 7.3L with around 130,000 miles. This was sometime between 2000 and 2003. I did notice both an increse in power and mileage. But, my silicone number were through the roof on my 1st oil sample. So, I measured the height against the OEM, and it was the same. Cleaned, re-oiled, and changed the engine oil & filter. Pulled another sample at 2000 miles, and silicone was again super high. I went back to my OEM, changed engine oil and filter, sampled again and the silicone number was back to normal.

    So, I'll never use a K&N again.

    Did you over oil the filter? I only use K&N in my bikes for the last 20 years and work just fine. I know I use Amsoil foam airfilters (back in the day) and silicone where high from over using too much oil.

    I now use Amsoil EaA air filters and so far UOA's are fine.

    But the Powerchokes (and prior) are not easy on oil.
