Spark plug Denso or OEM Audi
120k miles on my 2015 a3 with a stage 1 tune. I did timing belt, tensioner, and water pump around 100k miles. Costed me like $1k. Also did spark plugs and a new battery, which was another $600.
Vehicle:
Audi A3
Mileage: 120000 km
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
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
I ran Denso iridiums for 100,000 miles on mine, they looked usable when I pulled them. Replaced them with NGK's, no difference in power generated.
Pros: high mileage, usable condition
Cons: no power difference
Mileage: 160934 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
the tips of the IKH24s break off in expensive TTRS engines.
Cons: tips break off
Vehicle:
Audi
