BMC Race filter ok for street?????????

I just installed a BMC Race filter on my 2012 ZX-14R. I live in Tucson, Arizona. I was wondering if I really have to worry about particles coming into the engine. I don't ride it a lot and want to do some land speed racing. Is it pretty safe or do you think It really hurts the engine that much? Our air quality changes here daily. Some days are perfect, some days you can taste the dirt in your mouth (kind of crunchy) seriously!!!! But I do like how much flow the filter has.... It is a race bike.... Am I thinking about this too hard???? Has anyone installed one on your bike? Does it make a difference? Last night after installation I noticed the throttle response was much crisper...

Thanks!!

If I remember correctly there is no real gain to be had. I would say pull the metal screen off the stock filter and run it.

Aftermarket ‘race’ air filters are great for keeping bugs and birds out of your engine... but engine killing, ring sticking, piston scuffing, dust particles as large as 200 microns will flow right through!

It’s funny (and a little ironic) that the test used to rate air cleaners is honestly called the ISO 5011 Arizona Coarse Dust Test.

Typically, we recommend stock air cleaners for street use and complete removal of the air cleaner in 90% of race conditions… UNLESS you are in a dusty atmosphere; then we recommend an aftermarket ‘race’ air cleaner. If you go to our site, you will notice that we do not even sell aftermarket ‘street’ air cleaners, as we have found that they don’t work as well as stock.

I say ‘typically’ because we have recently discovered an aftermarket air cleaner that is oil free (thank gawd, no more over oiled and/or constantly changing A/F ratios) that has the performance of a ‘race’ filter, but the filtering characteristics of an OEM paper filter. To clean it, you just blow out the dirt with compressed air from the opposite direction that it arrived – re-install and get back to riding.


Brock's Performance will soon be offering Sprint Filters. We thoroughly tested them against other brands in multiple applications. I was most impressed when they beat the stock BMW filter on the dyno, which is hands down the best designed OEM filter I had tested to date. Stay tuned to our site for details.

Newrider14, I would suggest following BlackMagic 14’s advice for now.

Thanks Brock! Do you think there would be any chance of the filter to collapse or buckle if the metal screen is removed?

New14rider,

No. Performance enthusiasts have been doing it for years with no ill results. It's simply a barrier to prevent a rock or other high velocity object from penetrating the filter, primarily when wet. While it could happen, I haven't ever seen or heard of it myself.
