i just purchased some NGK-BR7ES's and i was wondering they will work in the lightning....is that the same part number that PSP sells? if not which one do i need?

 

Sorry, those are not the correct plugs. What you need is the EF, not the ES.

 

what is the difference in the plug?

 

Why are you using the 7s are you using N2O?If your not you should try the NGKtr6s,they work very well for me anyways...

 

yes i am running a 90 shot of nitrous

 

UMMMMMMM.......Nitrous!!!!

 

I would run TR-6's!!!!!!

 

I can tell you the difference, since I went through this myself. The ES is not a tapered plug. You will notice the standard 5/8 spark plug socket will not fit it. It's a 13/16 I believe. You will notice the 13/16 socket does not fit in the hole on your truck. Take the plugs back now. They don't fit.
