Don’t kill me for this question, but are there 16 total spark plugs that have to be changed? Is this thread about the ones that are the hard to find ones? I know about the eight on the bottom but didn’t realize there were 8 more. By the way I have a 2017 Supra SA450
16.........top and bottom.
Do you have a video or guide for the top ones?
The link parrothd shared still works. It's a Google photo link that shows the steps. Basically you have to unbolt the Ecm and it's bracket, a fuse box and the pcv valve. Then you can pull the tops.

Hey guys, what is the difference of the Indmar recommended Motocraft CYFS-12FP (597037-16 in manual) versus the Motocraft SP-526's? Are the heat ranges different or anything? Also what is with websites charging crazy amounts of money for the CYS-12FP plugs? I've seen anywhere from $250-600 lol. I go on Advance Auto website and they sell the CYFS-12FP plug for only $5.19 which it to $83 total. That's a fraction of the cost compared to boat-specific websites and stores.
No difference between the expensive and cheap ones

The SP526 is identical to CYFS12FP
$61 is a great deal for 16 plugs

On both my Raptor engines at 300 hours, I have installed NGK Iridium plugs, both have ran like tops! It also helps I can get them at cost from a speed shop friend of mine.Quote:
