what he said...and then replace them with Champion RA8HC, $1.39 a piece.
btw, does anyone really think that HD makes HD plugs? Compare them with that Champion RA8HC and I think you will know who makes the HD plugs,

crazy talk. these plugs are operated in an ECM/EFI system. reality check, they are good until they ain't. no way they will get fouled or otherwise with EFI. frankly, snatching on the plug wires and removing the plugs to check the gap will do way more damage than anything.
leave the damn things alone until something (mileage/performance drops) tells you they need to be replaced.

I don't see the point of changing plugs at 5k miles....Both a waste of money and good plugs. Run 'em till your performance and/or gas mileage suffers...IMO, the less you got screwing the plugs in and out the better.

Gotta agree with Crusing, Bwana, and Oley on this. You gotta know when your plugs aren't firing right, and it's an easy fix (clean/re-gap or replace). If it ain't broke, don't fix it, just have a spare with ya. That said, preventative maintenance (clean/gap) won't hurt ya in the interim.
