Air Filter for 748 - Ducati.ms

BMWKen · Apr 3rd, 2007, 3:37 pm

What type of air filter are you guys using on your 748?

I removed the tank on my 748 (first time) to prepare for belt replacement and valve adjustment, and discovered that it has a single foam filter that covers both velocity stacks. The filter has "FBF" stenciled on it.

The strange thing is that it also still has the OEM filters in the air runners.

Should I stay with both the foam filter and the OEM filters, or remove the OEM filters and just use the foam filter, or discard the foam filter and just use the OEM filters? Or is there a better aftermarket filter that I could use?

Thanks!!

I have the exact same FBF foam filter. I took the Air filters out of the runners and threw them away. When I first received the filter and slip-ons chip in the mail I didnt know where the stock filters were. I had take the runners apart to find them.

Maybe the previous owner thought the bike had no filter so he installed one

. Atleast you know the bike has not injested anything foreign because it has had ample air filtration.

FYI: FBF stands for "Fast by Ferracci".

The seals under the tank are not known to be the best, and you can often find a lot of crap in the airbox. When I went to do the 6k service on my 748 (at 5600 miles), there was all sorts of dirt and even small pebbles that had made their way into the airbox. I could never make up my mind for which style of aftermarket air filter arrangement I was going to use (the one as you have or the Mad Duc filters that just fit into the velocity stacks), so I'm now up to 11k miles with the stock filter arrangement. I'm dreading taking the tank off for the 12k service and seeing what is in there this time.

For performance, ditch the in-tank filter and stick with properly installed OE runner filters. Keep them clean, ensure they're properly fitted and that the tank is properly installed and the seal is in good shape, and you'll be just fine.

Some will argue that an in-tank filter provides better filtration, especially in the case of a runner coming off in a crash. My personal experience is not conclusive with this, because the used 996 I bought had an in-tank filter that was improperly installed by a well-known tuner, and allowed all sorts of crap into the stacks and motor, until I junked the filter and re-installed the stock filters.

Regardless of my experience, the filtration aspect may or may not be a primary factor for you, but know that you will lose some torque and power with the in-tank filters.

I know that what you say is true OldBaldy but my airbox was also quite dirty when I installed the foam filter. I don't mind sacrificing a little power to insure that my bike is not sucking any crap down the stacks.

That's fair enough. Each person decides their own priorities

(I spray chain lube down the tank side of the runners, and inside the tank to trap any gunk that does make its way past the seal or filters - and am happy with the OE setup. Have yet to see any issues at all during strip-downs of the top-end, regarding cylinder or piston or valve or seal wear from running the stock setup )

I thought the FBF was probably Fast by Ferracci as you have confirmed, but they don't list this particular filter on their website. Perhaps it is not manufactured anymore.

Judging by how much crap was in my intake trumpets DESPITE having a properly installed ITG foam filter, and knowing that over-the-intake filters only hurt power, I'd stick with stock and chain lube in the airbox/runners. I had one of those filters in mine and I ditched it. Problem is when you run without filters in the runners, huge amounts of dirt and dust get into the airbox itself, so much that it overwhelms the foam filter as soon as the oil starts to dry up.

I did the BCM filters. Pricy, but they totally seal the airbox. Installation is a bit trickier that a typical one as you need to do some drilling and remove the airbox, but once done they are great. I also do chain lube down my air runners. It's amaze-za-zing how much crap gets stuck in there. Looks like flypaper...
