    I'm looking to pick up some carbon air boxes and was wondering which filters I should get? Looking at BMC vs K&N. Is one better than the other?
    Thanks.

    I've read the oiled filters can cause MAF sensor issues.

    I think that over-oiling is the biggest issue with these filters. I don't see how you can go wrong with either. Make sure they aren't too oily right out of the box too. I have K&N but am very careful to not over oil when I clean them. Contamination of the MAF sensors is what you are guarding against. Make sure to clean the ducting to the MAFs when you service them to get any residue off.

    I've heard that k&n don't filter that well. I've heard of multiple times now when a service has been performed and there is dust in the intake runners. You can see pinholes through the filter when looking up at the light. If your eye can see through it, so can dirt.

    I chose to get BMC when i replaced my airboxes as it's what Ferrari uses in their F1 cars.....plus I'm not a big fan of K&N as I had MAF problems with K&N's out of the box (not on my Fcars but on some of my Porsches).

    You will probably get replies on all sides of the fence and there are many threads here on the topic.

    Your car so do what you want to do.

    Paper. There is no evidence that the paper filters are a significant enough restriction to warrant possible oil contamination of the MAFS. Yes, they might not be a problem so long as not over-oiled. But the MAFS technology is very sensitive to oil-based contaminants, and won't necessarily throw codes even though they are robbing your car of horsepower. It's up to you to decide, but FWIW, I run paper filters inside my carbon fiber airboxes.

    So there are 3 different opinions on this topic. I read K&N's website and they claim there were no issues with their filters causing MAF sensor failure. Any other first hand experience on this topic?

    Only with my M5, which had the same kind of MAFS. Performance degraded due to MAFS contamination. Didn't realize how badly until I drove a friend's identical car and realized how much stronger it was. Swapped MAFS and the power increase was instant and noticeable. I didn't notice because the power loss was gradual and in normal day to day driving, the engine still made more than adequate power.

    As a result, I will not use any oiled filter again with this type of MAFS system. Note there was no "failure" and at least with the BMW, no codes thrown. So I could easily see a filter maker making the true claim that their products don't cause MAFS "failures". People are welcome to their different opinions and to try using whatever aftermarket equipment they want. After all, it's their cars. If you use them anyway, do some baseline 0-60 runs and periodically check to see if they've gotten longer. Or use dyno software app on your smartphone (or a dedicated device such as Racelogic).

    I'm of the same opinion - it is worth risking MAF damage for a 2bhp gain on a 400bhp car? The risk/reward ratio doesn't stack up.

    What is the engine life of an F1 engine? I have no idea but they run crazy high rpm so I'm sure it is not that long.

    I have just installed K&Ns on my CF boxes

    Should I be worried if I fit new ones and replace instead of re-oil them???

    That is an option but I was thinking I'd get a little more performance if I used one of the above mentioned air filters.

    The is no comparison to a regular filter and the Green Dragon Filter.
    See the video and so how much more air can be pushed thru your engine

    I have used K&N and experienced MAF issues on a C5 Z06. It was my fault though as I over-oiled them. I had BMC on my CS with no issues. Only apply enough oil to turn the filter light pink. The BMC's are Italian and what the F1 team uses so I figured they'd be good enough for me. Oh, the extra intake noise of the extra air being sucked in was cool too. lol

    How often do the Green Dragon filters need to be recharged?

    F1 cars don't use the same MAFS as our street cars do, and even if they did, they would get fresh ones for each race so wouldn't encounter the contamination issue. Race engines are routinely rebuilt much more often than street cars, too, so additional dirt isn't the wear issue it is for our cars. The main reasons for running air filters in race cars is to make sure bigger particles don't get sucked in and cause failure during a race, and to straighten the air flow entering the intake manifold to provide optimum flow with the least turbulence. They don't care if smaller grit wears out the rings or contaminate the non-existent MAFS. An after-race or mid-season rebuild takes care of that. When's the last time you rebuilt the engine in your CS? When's the last time you dyno'd it to make sure you are still pulling the same BHP?

    When you buy a K&N new make sure you dry it, this way you know its not over oiled and then you have no issues.

    When cleaning do the same ... IIRC, 360 filter is also used in Toyota ...

    Green Dragon is interesting ...

    I guess it depends on how and where you drive your car.
    I would say 4000 miles or once a year whichever comes first.

    I've used BMC and K& N for years on my p-cars. I never had a problem. When it's time for a new set, don't re-oil and risk fouling the MAF's, just buy a new set if that's what you want to use.

    Been using K&N on my 360 for a few years now with no issue.

    Been using K&N filters on every car I've owned with no issues.

    If you do not know how to properly clean, dry and oil you will run into issues no matter what. This would be the case on any rechargeable filter no matter what brand you use.
