Aftermarket spark plugs??

[cat0020]

Anyone using aftermarket spark plugs in their Oilheads?

What brand?

What model?

What kind of results?

How old is your oilhead when you changed to aftermarket plugs??

How long have you used aftermarket plugs?

We've had Autolite 3923s in our RS for about 30K miles. Less surging and they cost all of a buck and a half.

I think we first put them in at about 30K or so.

Autolite 3923. Did more to reduce the surging than anything. So cheap I change them every year for no reason.
