Thanks! This is for a stroked 4.1 stage II hydraulic cammed street car. XFI and TR6.
 
Start with a NGK 5238 and check them to see how they look after every 50 mile or so.

I have good results with them using the XFI computer and a TR6 on the street and e-85.
 
i have had very good luck with the NGK BR7EF (3346)..with both the stock computer, XFI, stock ign, and TR6...they are readily available at most parts stores too.
