I bought the NGK TR55's based on all the good reviews here. This plug has about twice as many threads as my current plug. A quick check on NGK's web site revealed that I should be using UR5's. Oh well, back to the parts store...
I had that problem with NAPA...They had only one listing for the '86; the iron head one...
I really couldn't tell what it should have had when I bought it; it had 7 aluminum head plugs (flat with copper gaskets), and one taper-seat plug... :eek:
