Bosch plugs are just fine! I’ve been using the platinum +4’s in all my atlas engines for over 10 years now.. NO ISSUES and.. no gapping problems, 4 electrodes.. what a concept! Just pulled the ones out of my canyon I5, installed around 2012, 80,000 ish miles, wow, they are cleaner than the AC delcos they replaced and the delcos (factory installed) only had about 28k on them.. it’s all about what works for you..
