bmc makes two different filters. how do you know which will work the best?

YZF-R6 - Air Flow Restrictor Included 08> Flat 515/04
YZF-R6 - Air Flow Restrictor Included 08> Flat 515/04 RACE

The race filter allows a lot more air (and dirt, bugs, etc) to flow through your engine, which can theoretically allow it to make more power. However, the engine has to be tuned properly to take advantage of that power, which will all be in the top end of the rev range, and you will lose some mid range and bottom end. Some bikes are affected worse than others. For example, on my 2005 GSXR600 when I tried the K&N filter it lost so much midrange that it just wasn't worth it for me, so I ended up going back to an OEM air filter within days of getting the K&N installed.

ahh alright so then no filter for me, i like the mid range, do not want to take away midrange to get more top end rather have it the other way.

dont get scared away from a filter because of what it did to a suzuki lol. a filter is one of the best things you can do to anything, because stock is so restrictive. what he is saying is that just like a full exhaust, you can not get the most out of it without everything working WITH it. including the computer, which is where a tune comes into place. I would say stay away from the race BMC only because street riding is not the same as racing around a track, as chango said allowing alot more stuff to flow through it. I would say look into a K&N I just ordered mine today, and had one on my old 07 (double negative?) after the BMC. I trust K&N alot.

ok, what about like the gytr? also from what ive seen k&n doesnt have one out for 08 only for the 06-07. i knew all has to work together, thus im trying to figure out what i need. im most likly going to go midpipe, slip-on, pcIII, filter, and maybe change the sprockets. id love more low-mid range as i really dont go top speed fast.

Yeah, I didn't mean to scare you away or anything, that was just my experience with my Suzuki. With a proper remap you can actually gain some midrange with an air filter. Suzuki just makes their air filters so well that an aftermarket was a waste of money.

If you are going to spend the money for a slip on andmid pipe, AND pay for a tune as well as a filter, save yourself the time and money and get a full system. I mean granted the one I am running isnt the BEST but I like the look and sound, and there are most definately performance gains. I mean last I checked I didn't see anyone with a last name of Rossi or Hayden on here lol. I went with the full yosh system when I realized the slip on I wanted was only 200 and change less than a full system. I did the math and went full. also GYTR makes quality parts, and yamaha backs them, I have never personally used any of them I've only heard a handfull of bad things about them though. with a filter though I dont think you could go wrong, but as a majority of people would say I'm sure K&N is an industry trusted and used name.
A friend of mine had a BMC race, after about a month or so of riding he found dirt and particles in the intake and throttle bodies on his Aprillia. again, you do the math. we dont need a RACE filter for the street, for reasons as above listed. I would say the K&N and GYTR is 6 of one and half dozen of the other.

also I wouldnt change the sprockets, I think you might regret it. depends what type of riding you do. I did it on mine and did not like it.
