New in the box NGK 7164 spark plugs, I purchased them to replace the plugs in my 350 MAG but sold the boat before I got to it.  New boat has Volvo's that take a completely different plug.  Merc and other sources recommend these for the Merc 496's as well.  Its a performance plug but I wanted them for the long life Iridium provides.

Full set of 8, I won't split them up.

They run $6-15 online...  

I'd like $40.00 and I'll ship the set for free in the USA.

    Great deal! Those are $6.99 each here locally. I wish I knew if I needed them or not. I dropped my boat off in Phoenix today getting the swim platform installed.

    Hmmmm, wonder if they'd work in my 496'?  I'm probably coming up on due, but it'd be good to have spare either way.

    @trashman you can take them.  I'm not sure what I need (I'm sure I'll regret later).

    How much do we have to switch sparkplugs? I used to do it every year on my old boat engine, was thinking maybe this newer 383 wouldn't need it as much..?

    Ok cool,  I responded earlier on my phone while I was in the middle of something and didn't see your post.  I'll take them as soon as the seller contacts me.  Thanks.
