Spark plug recommendations

[KSC 2019 XLT]

I have a 2019 Expy XLT 4WD with about 77k miles and looking to replace the spark plugs. Looking for spark plug brands and models you all would recommend.

Stick to Motorcraft SP594. I just replaced mine at 113k miles few days ago. Last swap was at 50k miles. I recommend to change out every 60k miles.

I changed my original plugs at 65k miles, and they still looked nearly new, no erosion at all.



I used NGK 90495 LTR6BHX Ruthenium HX

Did you measure those gaps??

I don't remember if I did. the only spark plug gapping tool I have dates back to when I owned Volkswagens in the early 80s..

NGK ruthenium off rockauto. Best deal I found. I changed mine at 30k for no reason, as they looked like they came out of a box. Zero wear. Gaps were all .028 across the board.

Just did my plugs and boots Tuesday.
NGK Ruthenium’s that I got off Rock Auto. #90495. $8.70/ea
Motorcraft Ignition Coil Boot - WR6151. $7.36/ea

They were all pre gapped and even across the board - 0.032". I had used these in my previous Expedition and ran great & smooth. I’m only at 25k miles, but the truck is six years old now, plus I bought used so I’m trying to establish baseline for maintenance items.

I feel like I was ripped off. Just paid $7.37 for the same boots at RockAuto about a week ago.

Sorry. That’s happened a few times to me. Like buying the stock market.
