I pulled what I thought to be my original plugs/wires this weekend (with the help of Jake) and saw that NGK'* were in there. Seems strange, because I was expecting Delcos. Maybe this old man that owned it before me was told NGK is performance or some garbage.

the Delcos are made by NGK....i pulled the plugs on my 2003 (they were stock with only 21k on em) and they were ACDelco, and i cant remember the number

they were prolly replaced at by a comparable plug made by NGK

I had the same reaction when I pulled my original plugs (NGK... not Delco )
I later saw that my ’00 FSM calls for the NGK PTR4B-15 for the L67 and Delco for the L36.

my 02 came with ACdelco'* that looked pretty weathered.

My Bonne came stock with the NGK plugs.

Hm...k.

These may have been originals then because they were FRIED! (caps means emphasis)

Either way the car runs a lot stronger and starts quickly.

Did you wear out your forearm removing the rear boots and plugs?

Jake ripped the boots off with his tool and I stretched like rubberman to get the plugs out.

I was reusing mine and the effort to remove the boot was surprising. I should have replaced the wires it would have been easier.
