Spark plug Denso or OEM Audi
You can usually find DENSO IRIDIUM Spark Plugs , which are the OEM Supplier, for about $15 each at any Advance Auto or other major auto parts store.
Pros: easy to find, oem supplier
Yesss got denso coils and spark plugs off their site and they have been great
Pros: great performance
And, before you get too far, are you replacing with the right plugs? I presume it’s the 2AZ 4-cyl since you’re not asking us how to get to the back plugs. The right ones are the Denso Iridium Long Life or the NGK Laser Iridium.
Check out getting rs3 spark plugs if it’ll work.
Pros: good idea
Vehicle:
Volkswagen Golf
I use Denso IK20TT and these spark plugs work every time, on both fuels.
Pros: reliable on both fuels
Vehicle:
Volkswagen Golf
I put denso 5310 in mine, apparently they are supposed to give you a slight increase in power if you use premium fuel.
Idk if I gained any power, but the car runs well.
Pros: car runs well
Cons: power increase uncertain
Part number: 5310
Have used NGK on my Toyota Prius v, works just fine, never had problems.
Changed them recently, still had factory Denso spark plugs, and they worked alright too, even after 121k miles of use.
Pros: works just fine, no problems
Cons: worked alright
Vehicle:
Toyota Prius v
Mileage: 121000 km
I have eqt and the densos and they are smooth
Pros: smooth performance
Vehicle:
Volkswagen
For what it's worth, I've changed my plugs twice (OEM to Denso to Beru-RS7) and never noticed any oil or any difference in color between the plugs.
Pros: no oil, no color difference
I said from the get go that the Densos were running like ****. Especially at wot around 110mp/h it felt like the engine was hesitating and lacking power. Idle was smoother with the Denso though.
Pros: smoother idle
Cons: engine hesitating, lacking power
