BMC race vs non-race filter - June 9, 2008, 07:51 AM

Which one ahould I get? I do occaionally ride in the rain and what-not. I don't race, but of course want the least amount of restriction without the risk of sucking up anything bad.

I've read some opinoins on this before, but can't recall what they were?

if you get the race filter, i would clean that thing weekly. the normal you can do once a month...


the holes are slightly bigger so you gotta stay on top of its cleaning..

Do you buy a condom to look at it? No you buy it to fuck.

I'm curious where you are getting that "once a month interval?
That seems a bit excessive.

I have a BMC filter, which is VERY similar to ever K&N I have ever used. Here is what K&N says Re: cleaning.

Quote:
How often do I need to clean my K&N air filter?

If you have not experienced a decrease in mileage or engine performance, chances are your filter is fine and does not yet need cleaning. To be more specific, the filter does not require cleaning if you can still see the wire screen on the entire air filter regardless of how dirty it may appear. When the screen is no longer visible some place on the filter, it is time to clean it. When used in normal paved road, street or highway conditions, our replacement air filters that fit in the factory air box should require cleaning every 50,000 miles and our large conical filters on an intake system should require cleaning every 100,000 miles. When used in dusty or off-road environments, our filters will require cleaning more often. We recommend that you visually inspect your filter once every 25,000 miles to determine if the screen is still visible.
I will pull my filter every other oil change, wipe out the airbox (which usually stays fairly clean) and shake the bugs out. I only clean and reoil once a year.

heres what I found on BMCs site


Quote:
Question: How do you regenerate a BMC filter?

We strongly advise regenerating the BMC filter using the original BMC washing Kit; the kit contains detergent and oil dispenser (spray or with batcher).
We advise regeneration every 15000 km to guarantee long lasting performance and duration. This value can change based on the environmental conditions the car is used in (e.g. non tarred roads, presence of pollen, dust,).
The stages for correct filter washing and oiling are specifically indicated in instructions inside the pack.
But I dont "regenerate my filter", drive KMs on non tarred roads or use a "batcher",
So I use the good ole Ammurican K&N directions.

Normal road riding, a month is probably overkill. The more dirty it gets, technically the better it filters.

Cleaning it more regularily would just ensure that you are getting maximum CFM flow through the media.

Depending on your other mods (exhaust...etc...) you may want the non-race filter because unless you have a power commander or some sort of way to adjust fuel you could run it lean.
