Twin Earth Plugs For Rb26

[Keeper]

Hi guys I'm having problems idenfitying the plugs I used to use on my RB26 when it was running, they were a copper with a earth prong up each side and a V Groove electrode from memory, does this sound similar or familar to anyone?

Just use BCP7RES

NGK BKR have a groove in the central electrode - dont see any "earth prongs" though.

That's them! Who makes them/ part number please

[JonnoHR31]

those exact ones are BKR7EKC, they dont have v groove like the ones you mention tho.

cant remember exactly but the twin prong is identified by either the K or C or both at the end of the part number.

have a google search for the ngk diagram that breaks down the part numbers, its all in there.

btw you can also get plugs with 3 and 4 prongs, kinda funky
