I went with NGK plugs and coil packs at about 95k miles on my 2.5. I'm about 40k miles later and. It's still running great.
Pros: still running great
Vehicle:
Volkswagen
Mileage: 95000 km
On a 2.0T it's pretty darn easy. The Gen 3+ engines have the bolted down coil packs with the ground wires/nuts, which can be tricky. You might need to counter hold with a thin style wrench, but other than that it's fairly straight forwards. I'd be sure to use only legit plugs from reputable sellers--there are a surprising number of counterfeit NGK (and Bosch and Denso) plugs out there. Fake plugs can cause more than just pesky misfires too, they can break off in-chamber and cause catastrophic engine and/or turbo charger damage. Not worth it to save a few bucks and potentially end up in ruin. NGK are the OE most of the time so getting the Laser Platinum or Ruthenium HX are recommended. Whether or not you want to replace the coils is up to you. I'd say it's too new for that and if you don't have a ton of miles on it, probably not necessary. The spark plug interval on these engines is comically short too--I'm not sure why VAG does that but they do that across the board on their engines. The original plugs will go for 2x the specified interval without any issue at all. If you are not super high miles and you pull them out and see "they look just fine"? Don't be surprised because they probably *will* be just fine. That said if you're still under warranty (base or extended), change them as specified.
Pros: legit plugs recommended, original plugs last long
Cons: counterfeit plugs dangerous, short interval specified
yup those are done.
the center electode is worn flat and the gap is way too wide.
just replace them. make sure yu use the specified NGK or Denso Iridium plugs.
Pros: replace them
Cons: worn flat, gap wide
Yes, they have a lot of buildup and deposits. Make sure you get that exact spark plug again same brand everything don't put anything other than the NGK that originally came with
Pros: exact spark plug again
Cons: lot of buildup, deposits
Vehicle:
Audi
Fairly easy to do,ive seen this plugs go past 150k honda tech here.
Pros: easy to do
Mileage: 150000 km
Factory plugs were causing the auto transmision to take longer to shift and jerk more suprisingly. I assume because the engine was acting differently than the transmission expected.
Pros: easy to do, cheap
Cons: expedited wear
Vehicle:
Mazda 3
Mileage: 60000 km
Also I like the NGK sparkplugs more than Bosch.
Had some problems with Bosch plugs once.
Pros: like NGK sparkplugs
Cons: problems with Bosch plugs
There is 0 performance or ignition upgrade to the ruthenium compared to motorcraft OEM ones. I tested the 2 back and forth for several weeks and saw no noticeable improvement in either. The car ran the exact same. Rutheniums run like $50 ish a set, motorcraft I can find for around $25 a set, no brainer, motorcraft. I am also stock. Don’t buy into the hype like I did.
Cons: no performance upgrade, expensive
Ngks are fine but be careful with them. I myself ran these and changed them at 10k intervals. I met someone at a car meet who recommended 5k intervals w these n I didn’t understand till my engine was gone. They can foul up and break inside the cylinder. Granted in my case it was my fault but it’s happened a few times w other ppl.
Pros: fine performance
Cons: can foul up, break inside cylinder
Vehicle:
Volkswagen Golf
Mileage: 10000 km
