Use the AC Delco iridium original plugs. Many sites will only show the double platinum as a replacement but every time I've ever driven an engine with those in it, it pinged or idled rough and iridiums always fixed it.
Eu tenho dois Honda Jazz. As manutenções são super baratas e os carros nunca avariam. Melhores carros de sempre... Até chegar à altura de trocar as velas... Sim, são a 40 euros cada. Preço normal.
Using the muzzler has stopped mine needing the spark plugs changed / having a cylinder go out every 6 weeks.
Over the years I’ve found that the factory recommended spark plugs typically work best. There are exceptions, but my ‘95 5.7 recently got some plain Jane ACDelco plugs and it is running great.
I just put in regular AC Delco plugs and it runs great.
Fresh AC Delco copper core plugs are all you need. Start with the stock replacements and go from there.
I just replaced my spark plugs on my 2012 1.4T with the ACDelco 41-121 ones.
The new plug is AC Delco 41-156. Cannot tell any difference in my Gen 2 after replacing plugs. It ran fine before and did afterwards as well.
I had the same experience and ended up getting a code. Swapped them out back to AC Delco and never had an issue.
These look like knockoff acdelco plugs.
