wondering if i should change to another set or not.... currently an 98 gtp with and l26 bottom end. stock heads ported lim and blower...... 3.4 pulley, 42.5 inj,ngktr6 plugs,slp headers no cat,xp cam...being its basically a top swap... should i change or is the tr6's around what i should use
 


humm.. what gap would be a good starting point... im oblivious to gapping plugs and whats too much not enough..
 
im on a rocker 3.4 set up, i went from 60,55, 53, and then 50. 50 felt the best.

also played the gap game on the tr6's first. then went to 104's. 104's were better right out the box and only got better with the gap shrink.
 




104's not in stock... wont be for a while... and the dick keep saying their not made for my car!! smh... whats equivalent to 104's?
 
put new plugs in... gapped at 050 misfiring at wot.... crazy all the plugs are in finger tight... and all the plug wires on

Who cares what they're made for.

That's why you tell them what plug you need instead of telling them what car it's for.

They're probably for a Ford Ranger.
