NGK tr55

 

Autolite 104's

 

Zex 82071-8 POWER RACER™ V8 SPARK PLUGS (97ss /nutek 383 - D1 - M6) B.

 

mine are autolite 103s or 104s i forget which

 

Denso IT20.

 

tr55's @ .037(...or as close as you can get between 35 and 40 on a disc gapper)

 

im using 104s but i keep fouling them when the motor is cold so i think it might be time for a change

 

Tr6

 

NGK Iridium

 

TR6s here, but what kind of set-up are we talking about?

 

Nothing better than NGK's

 

I know you have the RHS but will those work in a LT head?

I was going to run those...they are avaialbe readily and cheap, I have to order the AR103's

 

I bought some TR55's, but haven't put them in. I also ordered some stock Delco platinums, but they forgot to put them in the box. I'm calling tomorrow to order some other stuff. Should I just have them apply the amount I paid for the plugs to other stuff, or should I ask that they go ahead and send them. I have zero experience with the TR55's. Two sets of plugs for as much as I'll be driving this car might last 50 years. I think I'll be dead by then.
