3 posts in this topic

Can anyone tell me how JD's needle diameters compare to the stock OBDUT. Is the red diameter smaller or larger. Blue?

Thanks

JD Red is 0.1078" diameter, and the JD Blue is 0.01068" diameter. Stock needle is 0.1090" diameter. The end tapered tips of all three are about the same diameter 0.0880" to 0.0870" range. Needles are all the same length. :)

Thanks Indy! I've been too much tinkering at once(pipe, powernow,JD kit, airbox chop) and kinda got lost. Good to know that even the red needle is a bit richer than stock,at least on the bottom.

Thanks again.
