Is there any real difference between NGK BPR6ES-11 and BP6ES-11?


My 240z has a petronix ignitor installed and sometimes gives me hassles with the current BP6ES which advertise as pre-gapped.


Have called many retailers here in Panama and they only have either BP6ES or BPR6ES-11. They dont have BP6ES-11.


Can i use NGK BPR6ES-11? US$1.80 a piece!

 

The only difference between BPR6ES-11 and BP6ES-11 is that the BPR6ES-11 has a built in resistor (R) to reduce RF noise that can leak into other electronics due to the high voltage.
