any idea how i can find the specs of a spark plug?
way back when i bought a turbo “kit” i recieved
NGK 4554 non resistor racing plugs.
when i tried them N/A my car would intermittantly die at the
occasions redlight. that lead me to buying all sorts of unneeded parts that never seemed to fix the problem. as opposed to waiting, i installed the rest of the “kit”
once i got rid of them all my boosted misfire problems went away as well…
as soon as the psi started to go positive, it sucked.
after comparing them to the new plugs i bought (4177 tr6’s)
the tip is projected, and they are a resistor type plug with a projected electrode (vs. non projected)
I’m trying to figure out what made the car stall back then?
i even believe i gapped them at ~.035 or something.
any ideas?
