Caution!
TaoHawaii | March 24th, 2012
These fit perfectly when used with supertech keepers. They did NOT fit on any of the HONDA keepers that I tried. I tried the ones with triangles, dashes, and nothing. None of them fit! However they do fit perfectly with Supertech's keepers.
Perfect Fit!

Now I rev to 9,200rpm daily! No problems whatsoever
