    I am going to change the airfilter in my Blazer and have been looking at K&N filters. I have heard both good things (airflow) and bad things (pass dust) about these. Any input will be appreciated.

    Get one. Just be sure to keep it clean and well oiled. One of the best investments I've made.

    I'm running a 14"x4" and it is great not to have to worrie about a dusty trail cakein up a paper element.
    What is the negative you heard?
    From what K&N says a dirty K&N will still out flow a bran new paper filter!
    Have you played with one of thoes pingpong ball desplayes yet?
    It's a couple of tubes with air blowing thru it to make the ball float. You put a K&N filter inbetween the ball and the air and the ball goes to the top like no filter is in and the paper filter cannot hardly lift the ball at all...kinda neat...

    Anyway not buying filters all the time is the best part just clean the K&N from time to time and you off and wheelin again.

    I have a open K&amp;N and it's great. I've heard of people finding bits-o-dirt inside the K&amp;N(ie around the carb etc) but I haven't had that problem with mine or any of my friends. Just keep it clean &amp; oiled

    K &amp; N is by far the best. If anyone has been having dust sucking problems, they need to do a little more than just plop a new air filter in the case. Be sure to oil the K &amp; N with the filter oil, it also helps to spread grease on the top and bottom surfaces of the filter to stop any leakage there. K &amp; N also puts out a foam rubber wrap to go over the outside of the filter if you are in allot of fine dust. The best thing is that when it gets dirty, you can wash it out and start over again without buying a new filter. They work GREAT!!!

    I heard that the new holly air filters flow just as well but filter better, im not sure on this, just something i heard. I have a K&amp;N now and i have no complaints with it. They are supposed to be good for 10 years so it seems like it would be a wise investment instead of buying a new paper element every year

    I also have a K&amp;N on my '91 and run them on my street and off-road motorcycles. Question, how many of you are running the stock air cover versus leaving the filter open with an aftermarket (Elderbrock) style cover?

    I've just ordered a 14x4" K&amp;N air cleaner. Expensive, but I've only heard good things about them.

    Looks like the old filter has NEVER been changed! It's filthy, and the carb is covered in soot. I need to find out who the previous owner was, and kick their monkey ass!

    I've got the ample 5" filter on my Jimmy, which K&amp;N hasn't made a unit for. Any problems in switching to a 3 1/2" housing and K&amp;M filter?

    I picked up a K&amp;N Air Filter for the open-element air cleaner on my Blazer about a month ago, to replace a filter than had seen better days (The thing had been soaked a few times by mud bogging). I didn't notice a whole lot of difference with the filter, but I'm hoping that the oil-soaked filter will keep some of the splashes of water from killing it. I also ordered the foam pre-filter, soaked it in oil, and installed it over the whole deal...

    I have a K&amp;N for my '88 Camaro, and I did notice a slight SOTP (seat of the pants) difference....

    If your looking for water splash protection, don't get the open element, the stock unit does a better job. Rocko and I both had problems stalling in the water last Saturday with open filters

    I'm running open K&amp;N. Like it but of course got to watch for the mudholes. Got this from the desert race world, check it out.

    You said it, I didn't [​IMG] Think the biggest is 6 inch. With my idea for what I want, I may have to go to it. I'm running a 14x3 right now.

    That's a pretty cool setup. The principle that filter works on (cyclonic filtration) is how the air filters on our helicopters' engines work.

    It's always darkest just before it goes pitch-black...

    Every military vehicle I dealt with, HMMWVs, Bradleys, and Sheridans had the same setup. Must work.
