Hello, looking for the right plugs to install in my 1986 150 hp E150TLCDC. It has NGK BZ7HS-10 in it now, but when I look it up by application, it gives a Champion and an NGK number that does not have an electrode ground...just flat tip. I'm ok with that, but should I go with the Champions or the NGK, and then there is two part numbers for each brand. Just confused on which to use. Original plugs did have a gap spec, so was expecting regular style plugs. What to do?
Thanks for any help!
Jeff
