spark plug type for 2006 4.3gxi-F motor

[TwoWheels]

Does anyone know which non-Volvo spark plugs are correct fitment for the 4.3gxi-F motor? I found cross-references, but they all offer short and long reach. I do not want to drive out to the boat to pull a plug just to order some replacements.

Anyone know a correct replacement part number (platinum OEM equivalent if possible)?

Thanks,

Dave

First, the Delco spark plugs for engines with Vortec heads (which you have) is MR43LTS.
Next, I doubt you need spark plugs, and you'll not see any difference in performance.

Thanks for the info. I did a little research, and it looks like this is the non-platinum plug, with the platinum being 41-993. Does that sound right?

I get what you are saying - a 2006 boat should not need new plugs. I'm just building a cross reference so when I need something, I don't have to pay Volvo prices.

Thanks.

It dose sound right and you should keep in mind the best too spark plugs that just seems to have the less problems in marine is OEM stock ac delco or NGK.

MR43LTS is not platinum, correct. I'll trust your cross reference abilities, as I would never buy platinum plugs. Too expensive, and totally unnecessary.

Yep as boat teck states, LTS is long reach. Before Vortec heads, GM used MR43T for YEARS and YEARS. They started using MR43LTS when they started using Vortec heads in 1996.
