Hi all, my buddy just bought a late 90's sportstar with a 5.7 LT engine in it. Wondering what spark plugs go in it. Any ideas?

AC Delco MR43LTS. The pic is from the Indmar manual for those years.

Thanks for the info. Does anyone out there have a 99 Sportstar owners manual in PDF they could share with me?

Thanks for the info. I have found the red hose going to the engine for fuel. There seems to be no inline installed and I guess the filter is under the floor at the back behind the seat. Can anyone verify this the manual is unclear.

Thanks Guys.
