#18719, "Hello to all- Spark plug range question."
Hi, i'm Jon, i've been watching over the posts for sometime now but never registered with this one. I post a lot with dsmtalk. I have a '97 Eclipse RS with 109K on it, currently in an engine build with JE pistons, eagle rods, Hahn Stage 1, CM stage 1, new wires, etc. etc....I need to figure out what spark plug range is one colder than stock. I know what one range hotter is. If anybody could help, i'd appreciate it.
