View Full Version : Spark plugs for ATI stage 2?

09-16-2002, 10:06 AM
What is a good spark plug? I've been running TR6s ever since I've had nitrous or a SC on this car but recently people have been saying they suck. What is the best plug which is 1 or 2 heat ranges colder? Thanks for the help.

I've never had any problems with the TR6'S ... That's my recomendation.

Hmmmm....what does everybody else use? My car misfires quite often so I thought maybe I should try something else.

Jason@GWP likes an Autolite... I forget the number.

Well Mike if thats what you use then I find no reason for me not to use them. If you didnt know what you were doing you wouldnt be putting down as much power as you are. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
