Spark plug OEM FORD or Denso
Ive been running eBay denso plugs for 4 plug changes. You need to read reviews and look at the packaging to make sure they're not counterfeit. They've lasted me and performed exactly as they should.
Pros: lasted and performed
Vehicle:
Toyota
I changed my coils and spark plugs and it fixed this same issue
Pros: fixed same issue
Vehicle:
Ford Focus
I have a 2012 Civic LX (purchased new) and replaced the original spark plugs at 100k miles with **Denso 3483 (DXU22HCR-D11S)**—which were listed as compatible on RockAuto at the time. I’ve had great results and am now at 200k miles, looking to replace them with the same.
Pros: great results
I had this 8 months ago in my FG
New spark plugs and coil packs fixed it.
Pros: fixed the issue
Vehicle:
Ford
There is a noticeable improvement in performance when I cross over into the next country and refuel. This is what my denso iridium plugs look like after 20k km. I had a misfire. New plugs today, and the misfire is gone
Pros: noticeable performance improvement
Cons: misfire, poor fuel
Mileage: 20000 km
Denso or NGk for anything and everything preferably dual ground spark plugs. I would get them rockauto as they have the best price and you can get the OEM brand.
Pros: best price, OEM brand
Vehicle:
Toyota
Get the right dual electrode spark plugs, Denso or equivalent. They’re cheap, around $5 per plug.
Pros: cheap, around $5
I replaced the plugs with DENSO 5358 roughly 10K miles ago.
Mileage: 16093 km
Part number: 5358
The previous owner had installed some Denso IKH24's that looked..... disgusting. In fact, I have NO CLUE how the car ran as well as it did, as the tips from the Denso plugs were gone, and the gap was 0.055. The car still had a slight miss after I did the coils last month which prompted me to replace the plugs.
Cons: disgusting appearance, tips gone, wide gap, slight miss
Vehicle:
Kia
Part number: IKH24
During a 300 mile trip in 100 degree weather, my car decided to start shaking horrendously, and the check engine light started blinking. Ford Pass notified me of a cylinder misfire. Apparently the spark plug was missing a piece, and there was extensive damage. Metal debris throughout the engine, turbo charger, multiple lines and drains. Everything has to be replaced.. but luckily it’s all covered by the 5yr/60k powertrain warranty. Such a huge failure at 46k miles is disappointing. I love the car but definitely have trust issues now.
Pros: covered by warranty
Cons: spark plug failure, extensive damage, disappointing reliability, trust issues
Vehicle:
Ford Bronco
Mileage: 74029 km
