Another spark plug thread...

[RickDizzle]

Ok guys, trying to make sure I have everything ready for the arrival of my Raminator. The engine comes with a JIDICH A7TC plug stock. Appears to be a cheap china plug. I'd rather run an NGK plug vs a cheap China and risk having the plug fail or it fall apart in the engine. I had some buddies run the plug and they are telling me that the equivalent NGK plug is a NGK4629. Just wanted to see if you guys have experience with the JIDICH A7TC and make sure running the NGK4629 wont cause me any issues. Figured I'll buy a four pack for break in and tuning. Appreciate the help!

Actually you should get the resistor version. It will help suppress radio frequency generated buy the high tension lead.
So CR7HSA.

Great info! What kind of power loss or potential issues could I see from running a plug with a resistor? I remember reading back in the day that running a plug with a resistor in an application not initially intended for a resistor plug can cause issues as the spark delivered is less powerful? What you guys think about that?

No issues. That was and is a myth. All the resistor does is suppress rf interference.
