Hi everybody!

This is my first post - I'm new to the forum (and to zeds in general) so go easy on me! Got my first Z, a '79 280ZX 2-seater a few weeks ago. Rather noisy, but hopfully not for much longer (thanks to moggy for the exhaust :) ).

Sorry if this has been asked before, but what plugs do you lot recommend for a 280ZX? The original manual says BR6ES-11, the haynes manual says B6ES-11 and the NGK website says BPR6ES-11. And it's currently got some bosch plugs that don't seem to match any of those!

Cheers

Matt

BPR6ES-11 is the favoured plug - "B" indicates 14mm thread diameter and 20.6mm or 20.8mm hex, "P" indicates projected nose, "R" indicates a resistor plug, "6" is the heat range, "ES" is standard copper core type and "-11" is the gap in mm (i.e 1.1mm, not 11mm!!

So, a BR6ES-11 would be fine if you didn't require a projected nose and B6ES-11 would be fine if you didn't require the supression characteristics of a resistor plug. However, supression helps sensitive electronics to perform efficiently (like your ECU), keeps the radio noise-free and won't upset your neighbour's TV reception!

Bosch numbers won't bear any relationship to this and they are not made by NGK who make the best plugs of anyone (IMO). Someone with the right reference books should be able to tell you what the right cross-over plug would be.

bosch number WR7CPX =NGK BR6E11
bosch number W7CPX/W7CX/W7CCX = B6ES 11. NOT SURE WHY THIS ONE HAS SO MANY VARIATIONS OF PLUG, BUT THATS WHAT THE BOOK SAYS AND NO REASON WHY, SORRY!
