Just got a quote from the dealer. $450 to replace all 16 + $165 for a fuel injector cleaner.

So @Huck what tools did you need to get at those ones around the steering linkage?

Small hands (no jokes ******) and a full ratchet set worked for me.
Why did you go with the ngk-6510? According to the part look up on summit racing the ngk-6509 is for the Ford Raptor. Only difference I can see between the two part numbers is the heat range number.

Ngk-6510 is a 7
Ngk-6509 is a 8

I can't access the chart here at work, so not sure which is the better? Look to both be the same price.

I don't recall why I choose the 6510, I think read somewhere that the one range cooler were better for what mods I had at the time. I think either JDM or Livernois recommended them also. I also have used NGK pretty religiously on my quads and sleds over the years. A lot of it depends on what tuner your running also, 5* I think recommends Motorcraft.

The motorcraft part no. SP-526 are about half the cost at $4.49. Lol...

I believe the 7 means it runs in a cooler range than the 8. Not really sure though.

Ya the cheapest I found the ngk's were around $7.75-8.50. The one range cooler I know makes a difference depending on how you modded the engine and how aggressive of a tune you run.

So for the long tube headers and constant performance tune I should also get the NGK-6510. Cooler = better.

Thanks for the help.
