Bernd, you probably should have went with the IK20's. Denso says that for
every additional 75-100 HP, go a heat range cooler.
Anyways, keep us informed. I'm running NGK iridiums equiv. to the IK20.
They run good, but my engine is stock, other than a Z-tube, jet S-II and a
muff. I get better gas milage though. I just got 21.68 MPG coming back from
SW VA. I was running a steady 70 MPH on I-81. 179.xx miles on 8.30
gallons..gas was .95 cents/gal !!!
