If you live some where hot, have a tune, or are hard on the car I would do one colder and get the 2309 instead of the stock 7913.
Any correct sized , heat range and gapped NGK plug will work fine but some will need to be changed more often. BKR6EIX for example is a good choice, it is iridium tipped and not expensive.
Always stick with NGK. However, NGK has different lines from copper, to platinum, and iridium. Iridium is more expensive, but will last longer. Given they're a bit of a PITA to replace, I'd go with these. I've run them in my 2004 WRX the last 8 years.
if the car isn’t stock and has been tuned, you’ll want to follow the recommendations of your tuner/just put NGKs in it.
New plugs and coils went in and the misfire is gone. Sounds healthy too.
This is what a 202k mile spark plug looks like on an 2013 Lexus gs350 daily driver. Pretty impressed with it overall. All 6 plugs look exactly like this.
For spark plugs, denso or bust
Back in March two days after finishing the Water Pump replacement it started misfiring. I started with replacing the spark plugs with OEM Denso's, but that didn't fix it but was VERY NECESSARY.
I have the same problem with my recently acquired 2011 Sharan. Tried a suggestion of new spark plugs with no success.
I just put Bosch plugs in my 13 Veloster turbo and got 300 miles and it started missing replaced with the ngks no issue since
