If you have a clutch, you will need 6. I have a couple extra, so 4 more will be all I need. Somehow, when I got them for my current 2010, I ended up with 2 extra ("L" version). The "L's" look like they will hold onto the collection hose better and the muffler cover does not look like it will be that much of a problem. I am unlikely to change brake fluid after the engine has been up to temp enough for the muffler cover to be hot enough to be a problem. I guess I need to order the other 4 I need because I will be wanting to change out the brake fluid sometime soon. I only have 4 months of faith in Honda brake fluid. My 2002, 2006, and first 2010's all had gelled fluid in the rear reservoir just a short six months after leaving he show room floor. The 2002 was gelled bad enough to cause rear brake failure. My second 2010 (aka.current 2010) got new brake fluid within a couple months of its departure from the show room floor so it never had a chance to gel.
