Spark plug OEM FORD or Denso
2019 4 gen - dealer sparkplugs were part number ZC20HPR11 > Denso spark plug.
I’m from EU, Scandinavia and that part number were on my original ones I pulled out.
Vehicle:
Mazda
Part number: ZC20HPR11
I went 134,000 miles on a set of spark plugs on my 11 Ford Fiesta which is, what, a bit around 215,000 km? They were still in decent shape when I pulled them, just a bit out of gap spec, and I was still getting really good fuel mileage.
Pros: good fuel mileage
Cons: bit out of gap
Vehicle:
Ford Fiesta
Mileage: 215000 km
Plugs(Denso IK22) coils(DENSO or Hitachi) and a valve adjustment, all due at 100k. They really do make them run better and much more reliably.
Pros: run better, more reliably
Mileage: 100000 km
I installed Denso a few weeks ago.
Pros: installed recently
Densos. Buy them off rock auto.
Pros: none
Cons: gapping suggested
Vehicle:
Volkswagen Golf
The Denso IHKs are my go to for the last 10k on their tune.
Pros: reliable, good performance
Cons: gapping info mixed
Mileage: 10000 km
Either one, but I found the Denso to be cheaper and easier to get. No issues with them.
Pros: cheaper, easy to get
Cons: none
Vehicle:
Volkswagen Golf
I bought the plugs from Toyota (Denso). I asked for the old plugs off. The plugs I got back were NGKs that were installed at the factory. I can’t say I notice a difference really (except new plugs did seem to make a difference).
Pros: new plugs made difference
Cons: no noticeable difference
Vehicle:
Toyota
Part number: 9008091180
I had EPC light/limp mode and P303 as well about a month ago on my '12 GLI (APR Stage 1+) at 102K miles that recently had a walnut blast and new Denso plugs at around 101K miles. Swapped coil packs as well and still P303 with EPC light/limp mode.
Cons: catastrophic failure
Vehicle:
Volkswagen
Mileage: 101000 km
Skip them, they are junk and a waste of money.
Get a good single platinum plug like the Denso 4511.
Pros: good platinum plug
Cons: junk, waste of money
Part number: 4511
