I got these AC double platinum plugs p/n 41-932. I looked the applications at the AC Delco site and the plugs all go to fuel injected engines. I couldn't find a heat range or a gap recommendation(just referral to manufacturer specs which wasn't shown)
Does anyone know if these plugs will work for 400 ci chevy with vortec heads....not too hot?
