4.7 Spark Plug recommendations/experiences

[Soulman]

I swear I have been searching....and searching. But I can't find a decent discussion thread about spark plugs. There must be many with experience on here. What do you guys recommend for the 4.7? What is OEM recommendation? Thanks, Dan.

OEM. Denso or NGK. Dont waist your time with anything else. Get them from the dealer as they're pre-gapped.

Aren't "all" modern plugs gapped? not being smart, serious question. I am looking at these- Denso IK20 Iridium

Amazon.com: 4 New DENSO Iridium IK20 Spark Plugs # 5304: Automotive

Anyone for or against?

I think the NGK and Denso plugs are gapped, but I agree with the important point which is to use one of those brands and nothing else. From experience I once put Bosch plugs in my Camry, and it would no longer idle or accelerate smoothly. .. Quickly replaced them with NGK and no more problems.
I recently bought 8 NGKs on Ebay for less than dealer price and all were correctly gapped. Good luck.

Most all plugs are pre-gapped !

Japanese car = Japanese plugs NGK or Denso

Not a tough job, but the drivers side can test the patience a bit, by no means is it a Ford Triton
