What are you guys gapping your 55`s at for standard N/A application?

i highly suggest NOT putting them in straight out of the box. you'll be amazed at how far off some of them are compared to others. most people gap them around .050.

If you are saying don`t change the car, too late!! I just haven`t figured how to change my sig yet! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Stock setting should be .059 but for every 50 HP you add you should drop off .004.

Tr55's come pregapped at .06. That is the stock spec. However, refer to Farmer2's post and adjust accordingly. FWIW, I have mine gapped at .05, and I dynoed 387rwhp.

Are the TR55`s the best for our LS1`s
I heard that the bosch plat. plugs are better?
I see that every one else is using the NGK plugs let me know?
