effects of using wrong plugs

[BruceSki]

thats good to know...

i put E plugs in a stock 300sx once when i first started riding... needles to say there were pretty little designs in the top surface of the piston after cranking it over.

you got two plugs in a 300sx?

you can also run a BPRXES plug
the p is a projected tip,
X is the heat range,
i usually run a BPR7ES plug
never a fouling issue, and helps it burn good
i also run a little thicker on the oil too and high compression

BPR7ES-11 is a solid tip plug
I have to remember to order some on my next summit order
