vs
Spark plug OEM FORD or Denso
Ignition coil most likely. I have done many dozens of them. Takes about 2 minutes to replace.
Pros: easy to replace
I recently got Denso (OEM) from my local o’reillys cheaper than the dealer (~$80).
Pros: cheaper than dealer
Bro ABSOLUTELY do the spark plugs yourself. I bought oem Denso spark plugs from Napa Auto for about $180. Then all you need is a spark plug socket w/ swivel head, 10mm socket, 12mm, a couple extensions, needle nose pliers, dielectric grease, and a pick to make life easier.
Pros: save money, easy job
Cons: time consuming for beginner
Denso iridium spark plugs
Pros: improved engine performance
Vehicle:
Toyota
New Denso Platinum spark plugs. Car drives great, no codes, no sputtering or stalling or hesitation.
Pros: car drives great, no sputtering
Vehicle:
Toyota MR2
Fitting a decent set (Denso or NGK) of iridium plugs is also worthwhile.
Pros: worthwhile
Vehicle:
Subaru Legacy
Swapped the NGKs (around 60k miles on them) for new OEM Denso plugs. That stopped the shaking for about two days, then it came back.
Pros: stopped shaking for days
Cons: shaking came back
Vehicle:
Lexus
Mileage: 96560 km
I already replaced the spark plugs with the Denso ones I listed though... Is this bad?
Vehicle:
Lexus
Mileage: 60000 km
I’ve had several Denso plugs do this on a couple Camrys I service, and our own. All 2.4 cars. Caused tow ins for both husband and wife’s cars. I’ve fired denso as a spark plug provider, too many failures.
Pros: null
Cons: too many failures
Vehicle:
Toyota Camry
I wish my Toyota 4Runner spark plug service was that cheap in the Toyota dealer. I was quoted $800 parts + labor for OEM Denso.
Pros: OEM Denso parts
Cons: expensive parts and labor
Vehicle:
Toyota 4runner
