Hey guys ive got a 1993 70 hp johnson model vj70tlets. So i ordered spark plugs off ebay to have some spares. The model i got ql16v champion 876m ql16v. I ordered this model because i looked at the schematics and it said this was compatible with my motor. Well i received them today and it seems there isnt the little metal peace that sticks off the end that the spark should jump?? IS This just a new style of spark plug or did i order the wrong ones
