Bosch Spark plug

Update: went Bosch for the plugs and ngk for the coils, the manufacturer plugs and coils were still in as if no one has touched them since the car was bought, I’m the third owner I believe. Each spark plug was toasted, easily double the recommended gap, and once I put the first two coils in (pulled code P0300, P0301,P0302) the problem entirely went away (coughing and sputtering exhaust, slow to accelerate, car shaking between 20-40 mph, rough starts) so I knew it was a go ahead for the rest of the coils. Feels like a whole new car all around, I can tell the engine is thanking me by what she’s putting out now ????

Pros: problem entirely went away
Cons: spark plug was toasted
Mileage: 179000 km

NGK Spark plug

NGK literally welded a platinum bar to the ground electrode. Is it going to be really butt dyno noticeable? Probably not. But at least it should last at least twice as long as the BKR7E-IX, since I've noticed after 20,000 miles, my mpg goes to crap. The projected square platinum electrode means wear resistance on the ground electrode, like the factory laser platinum spark plugs (PFR7S8EG) having a platinum wear disc on the ground electrode.

Pros: improved durability, wear resistance
Cons: not butt dyno noticeable
Mileage: 20000 km

I unknowingly sourced (6) NGK ILZKR7A Spark Plugs a year ago from eBay and installed them at 60K miles on my 3.6 VR6. I found out last week that the plugs were fakes. About a month ago I started getting random misfires. After detailing the issue in this thread here: https://forums.vwvortex.com/showthr...VR6-Cyl-2-Misfire-When-Taking-Off-Quick-From-Stop-Suggestions&highlight=Misfire I pulled the spark plugs and checked them last month and noted the gap was pretty far out of spec (weird for only being a year in), so I gapped them and reinstalled and the problem went a way for a few weeks. Last week I had another misfire, so I chalked it up to a bad batch of spark plugs and resigned to buy and install a new set.

Cons: random misfires, gap out of spec
Mileage: 96560 km
Part number: ILZKR7A
