vs
Spark plug BRISK or Denso
I went with Denso's on my 1.8T because that is what I had on the shelf. but I have ran anything and everything in vehicles over the years, and found that there is not much different between the different types.
Pros: not much difference
Vehicle:
Volkswagen Jetta
As always, go with NGK or Denso plugs.
Pros: reliable spark plugs
My car was fitted with Denso Power when new, 11 years ago. It has done 63K Miles (101K Km, way more than the data sheets above say) and the economy continues to improve
Pros: economy continues to improve
Mileage: 101000 km
Check out Brisk Silver Racing (listed as an option by EQT). You’d have to replace them more often vs iridium, but they are super inexpensive and more performance oriented (conductivity).
Pros: inexpensive, performance oriented
Cons: replace them more often
I was running APR coils and went back to OEM. That helped. So did going to the Denso 5750 plug and getting an EQT grounding kit.
Pros: helped with misfires
Vehicle:
Volkswagen Golf
The DENSO spark plugs are 6 for $23 at walmart. These get great fuel economy , smooth idle, Great Power.
Pros: great fuel economy
Have some I'm waiting to try out in my turbo 4age after using bkr7e ngks for years. I mean denso is an A1 company and they offer heat ranges colder than NGK so probably worthwhile for my turbo engine.
Pros: colder heat ranges
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 have used Rs7 plugs (meh), the APR recommended NGK plugs (rough idle, gapped correctly), and the Brisk ER12S. I'm on my second set of the Brisk, and plan to keep using them.
Pros: cheap enough
Cons: change them at 10k
Vehicle:
Volkswagen Golf
Mileage: 10000 km
the tips of the IKH24s break off in expensive TTRS engines.
Cons: tips break off
Vehicle:
Audi
