Spark plug OEM FORD or Denso

Denso 3289 is what I run.

398k on the clock, like 50k on these plugs, she runs clean and smooth.

Denso for my runner

Denso or NGK. Buy them from a real vendor not eBay or Amazon or anything like that

Replace with OEM - Denso. And yeah, get them from rock auto. Anywhere else is way too expensive and eBay is most likely counterfeit garbage.

OEM are actually cheaper than a lot of aftermarket plugs. Buy from a place like bell Lexus or just get the denso branded equivalent. They last hundreds of thousands of miles in some cases, so OE has certainly proved its worth

Denso 3297 on Rockauto are the Oem plugs

There is no risk, EQT specifically recommends them. Been running denso 5749s for over 40k miles and change them every 10k. Send it.

They look good but if the vehicle has 83k, they were replaced before, Denso is OE on toyota and Autolite are shit plugs so no way they were in since the car was brand new.

These things literally blast out spark plugs ????. Lots of other tricky issues too. I'm know I'm very biased towards GM but I wouldn't mess with this generation at all for a Ford lol.

ford. had the explorer with the long spark plugs that break. did them once and that truck wasnt around much longer. focus. dual clutch transmission failure.
