NGK Ruthenium 95125.. I ran a set for 25k miles w/o issue on Stg 2 E85 tune.. their gap barely if at all budged.. probably could've kept using them.. ymmv.
Pros: no issues, gap barely budged
Mileage: 25000 km
Part number: 95125
i just switched over to some ngk 91006 last week which smoothed out the idle. haven’t put enough mileage on them to give a solid review but it’s what many recommend and the car felt great at the track this weekend so i’d say they are definitely a solid option.
Pros: smoothed out the idle
Vehicle:
Volkswagen
Part number: 91006
I went with [Brisk ER12s](https://www.fcpeuro.com/products/vw-spark-plug-brisk-racing-er12s) plugs. They are one of the plugs recommended by EQT and I have been happy with them so far. Cheaper than the NGK/Denso plugs but downside is that they are silver based, so they will wear out faster. I am at 10k miles on them now and starting to feel a little rough idle; time to re-gap or replace them.
Pros: happy with them so far
Cons: rough idle, wear out faster
Vehicle:
Volkswagen
Mileage: 10000 km
Part number: ER12S
After further review i returned the autolite plugs and got NGK LKAR7BIX-11S Iridium IX Spark Plug (93501 Iridium Ix). ????
Part number: 93501
I also paid roughly $50 for a set of 4 iridium NGK spark plugs for my Audi a few years ago....even with an extra cylinder or two it shouldn't cost even half as much as they are estimating here.
Pros: inexpensive parts
Cons: high estimate
Vehicle:
Audi
FWIW, I just had spark plugs and coil packs done on my 2016 Jetta, $185 out the door at my local dealership
Pros: reasonable price
Vehicle:
Volkswagen Jetta
I have used NKG FOR THE PAST 6 years on the car , no issues at all. Recently replaced them with Bosch OEM spark plugs , it’s same shit , no difference.
Pros: no issues
Cons: no difference
Vehicle:
Volkswagen Passat
I just changed out my sparks and found out the previous owners put these garbage plugs in it lol replaced with quality Iridium NGKs
Pros: replaced with quality
Cons: garbage plugs
I ended up checking the ignition timing again, put in a new coil, new knock sensors, put in another fresh set of plugs, set the DPR MA to +5, and I failed my emissions test with the same results.
Pros: new coil installed
Cons: failed emissions test
