hi what spark plugs does a 440 take, the plug that came out are short reach plugs but the ones i brought are ngk bp6e longer reach plugs, they fit and dont touch the pistons only turned round by hand. any one know if these are right or recomend a ngk number, as i get them from work thanks

Champion RJ12YC or NGK R5670-6, both gapped at 0.35"-0.40"with a std ignition, should be easy to get

I used in both my engines,,NGK-FR-5 projected tip plug, both with gasoline and E-85 comp. ratios were 10.5 and 11.2 both had performance cams in the 240@.050 range. Excellent results with both!

ok thanks for that guys , will give the number to them tommorow and see if it works,they are short reach plugs too . so i wont put the longer reach ones in .thanks again jamie
