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?

It's a 99 model.

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.
