Quick spark plug question (Gapping)
Yes...yes... I did a search but did not seem to come up with much.
I will be replacing my stock plugs with the nkg 55's, and taylor thunderbolt wires.
I dont have anything done to my engine except a blackwing...
What should i gap the plugs at? I have heard people say 60 and others say 45. Currently they are gapped at 55 (i closed them a little last night)
Anyone???
Thanks
John

Re: Quick spark plug question (99firetruck)
The longer the gap the more spark the fuel will see - if your ignition coils have the juice. Depends on lbs/hr of fuel and engine timing as well. Most stock applications using platinum tipped plugs will work well with .060 gap. Your use of .055 is close enough since you do not have any mods that would otherwise need the additional burn.

I did notice from the factory the nkg's were at .057 - ish +/-1 and i did close it a little and reset them to .055.
I have not installed them yet - looks like i should be doing it thursday night / friday afternoon... The car has been running fine - i just heard these are the way to go.
Thanks!

Re: Quick spark plug question (Black_Magic)
Well, i managed to squeek a little time in on the car last night - I painted the calipers (Bad idea to try starting around dusk - thought my garage was lighted better) and i did manage to get the driver side 4 swapped before the bugs decided to attack me and i called it a night (can't drive the car anyway).
Hopefully i will get a little time tonight to do the finishing touches on the calipers and complete the pass side. :-)
Thanks!

Re: Quick spark plug question (99firetruck)
This is probably not recommended unless you like to experiment/resetting plug gap often. I have TR55IX with Taylor ThunderVolt 50 and I set the plug gap at 0.075" . Yes, it's humongous compared to the stock 0.055" gap :) Long sparks :)

Re: Quick spark plug question (99firetruck)
Spark Gap is very dependent on the combustion chamber characterisics. If you gap too far the velocities of the chamber can literrally blow the spark out. As you increase power, you increase the ferocity of the combusiton chamber. Thus requiring the gap to be narrowed.
