Spark plug NGK or AC DELCO

Go to Parker Performance. Look at the NGK Ruthenium’s.

Yes, they only sell genuine NGK.

Oem oem oem oem dont fuck up your car cheaping out on parts. Especially VQs they don’t perform well or usually don’t even work with aftermarket parts like those considering your plugs or coils. Got with ngk iridium or denso

I have a MK6 GTI and I replaced the Spark Plugs using the NGK recommended ones from Rock Auto and they were the OEM replacements.

I have the projected NGKs and they work great.

I run these on my stage 2 2019. Runs great. Like zero knock. Sometimes idle seems a bit less smooth when engine really hot but tach holds dead steady. Ran a set for 5k, inspected and put back in for another 5k then replaced with a fresh set and have another 2k on the new set.

I use NGK... it's the same 1/16 turn instructions on my Suzuki outboard (also NGK) and I use the same method of 1/4 -1/2 turn. Been good with those over 6 or 7 changes.

I was told that the Motorcraft iridium's are made by NGK?

I noticed a slight miss at while cruising between 67 and 70mph. I ran VCDS logs and found misfires on cylinders 3 and 4. Imagine my surprise when I pulled the plug for cylinder 3… no signs of any other damage and I have no idea how long it’s been like this. Never got a CEL.

I installed the new NGK Ruthenium HX plugs and so far everything has been great ????

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.
