Hello Frank,,,,, looking for NKG spark plugs........ NKG (R) BPR6EFS need 12 can you help????????

I don't stock a lot of NKGs
except for the the ones that came in the motors from factory

can get them in a day

I am a firm believer if it came with champion or ac or NKG from the factory as a new motor thats what should go back in

interchange numbers and closest equals factory installed plugs are co engineered by both the spark plug manufacturers and the engine manufacturers and will produce the best effects for the longest period of time

I will check stock when I get to store and let you know if by chance I have that number

thanks for asking

That is what was in the new mercrusier 4.3's that we dropped in.

try advanced auto they have in stock ngk

Already went that route but they do not carry that one and I don't want a cross ref. plug. This is what came from merc factory and thats what I would like to put back in.

Talked with a few shops today and one shop said they have my plugs. Cross ref. from the original number. 2 plugs were longer then the other 4. There were 4 different cross ref. numbers. The problem is different applications of the 4.3 block which have different heads. The different heads are why you need the correct plug. 4.3 blocks have been around for along time but some manufactures have made changes, and use at times different heads.. Mine are Mercrusier Vortex 4 valve per cylinder heads.
Thanks for the call back today Frank,,,, all good now.
