DE spark plug fit SR?

[cvex]

I have a set of NGK Iridium for the KA24DE , as pose side by side the DE is a tad bit longer(1/8") than the SR plugs. Will the extra length bottom out on the piston? How much clearance is the piston to head, anyone know?

shouldnt you buy sr20de plugs and gap them right, correct me if im wrong i think the gap is suposed to be .28

I know I should buy for the SR but i was just wondering if I can use these instead of throwing it away

NOOOOOO

1/8 of an inch is a mile when you are talking spark plugs.

you only want a bkr6e or a bkr7e. oh, or the platinum/iridium version of that same plug.
