Spark plug BRISK or Denso
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
I’ve been running Brisks for 30k now and haven’t had any issues
Pros: no issues
Mileage: 30000 km
Brisks are great plugs. Do be warned however, their groundstraps are softer than others and open gap much sooner vs other plugs. So you'll be checking them much more often and changing them sooner than the usual 10-15k tuned interval.
Pros: great plugs
Cons: softer groundstraps, open gap
Vehicle:
Volkswagen Golf
I went to Brisk ER12S a few weeks after going 1+ tune which are one heat range colder, same fitment as MK7.
Pros: one heat range colder
Vehicle:
Volkswagen Golf
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.
I use Denso IK20TT and these spark plugs work every time, on both fuels.
Pros: reliable on both fuels
Vehicle:
Volkswagen Golf
Brisk plugs off Parker performances page. The brisks hold there gap and seem to really last
Pros: hold gap, really last
I'm getting some knocks in all cylinders in the first revision, more than I did with the Cobb OTS map and stock spark plugs. Hopefully it gets sorted out in the next couple of revisions and if not, I'll have to check the spark plug gaps or maybe re-run with the Cobb OTS and see if the knocks are due to the tune or spark plugs.
Overall, the power delivery is great.
Pros: great power delivery
Cons: getting some knocks
the densos work fine, the point of swapping is not for any performance gain, rather to prevent shattered ceramic from raining into your cylinders
Pros: work fine (normal use)
Cons: risk of ceramic shattering
