ok guys, are these numbers good?

bur7eqp = N3A2-18-110

bur9eqp = N3A1-18-110

why the hell is there a spark plug saying option DX in the parts fiche? and are the set on the parts fiche good, it seems that there is platinum for the 7 and not for the 9.

please check it and tell me why i am so confused. check page 76 of 117 on the engine part of the fiches.

thanks a lot

I use BUR9EQP... this one is around $9 each
has platinum coating.

 

c'mon someone got to know this

 

those are old #'s they are
0000-18-n3a1 trailing (9's)
0000-18-n3a2 leading (7's)
