Spark Plugs For Darts Confused
What are the correct plugs for Dart PRO1's? I called NGK and they suggested BKR7EIX-11 (6988) with my soon to be set up, which is a gasketed plug. E-mailed Dart and they said that would be a good plug. Now I am hearing people using TR55's or TR6's, which are tapered seat plugs. Whats up? Thanks

You need to use a 3/4" reach gasketed plug. The tapered seat plugs may seal temporarily (sp?) but it's kinda like running the wrong seat lugnuts on your wheels - not gonna do for the long term.

DANG!!!! I installed the wrong plugs.
I INCORRECTLY assumed that since it was an LS1 head, it would use the same plug so I installed the TR6's in mine! (didn't leak either)
What would be a good TR6 equivilant "nitrous plug"??

The NGK FR6 should do for that or for more serious spray situations you can get into the NGK R5671-8's (std tip) or NGK R5672-8 (projected tip). Dart went with the 3/4" reach gasketed plug in those heads 'cuz there are more choices in heat range than taper seat plugs.

Open them up. The "extra" 5 on your TR5"5" stands for it coming with a factory .059" gap as opposed to a TR5 with a .039" gap. Now hurry up VN! Get that thing together and .

A tech sheet can be e-mailed to any of you that may not have received one with your heads. The tech sheet has spark plugs rec's, etc. For some reason it doesn't appear on our site either (?) but we'll get that fixed asap.

FWIW, it appears FR-6 doesnt exist except a FR6EI which is a 12.00 each super duper plug lol. FR5 is still a good number.
So it looks like 3922-3923 autolites for cheap, easy to find TR6 replacements for the gasket seat heads.
Or the NGK R5671A-8's or R5671A-7's (A is for 5/8 hex) but I dont think those are resistor plugs. May cause some interference in the PCM using the non resistor plugs..
If you insist on V-power NGK then BCPR6EY-11 (.044 gap) or BCPR7EY-11 should do it for colder then stock plugs.
maybe

The plugs they reccomended in your first post were irridium or whatever.
I'll just use the autolite 3922/23 for now
