Who makes the OEM Spark Plugs?
Re: HELP! Who makes the OEM Spark Plugs?
I just installed Bosch Iridiums in my 08 C70 T5. They look just like the OEM Volvo plugs I bought and returned. The car runs great!
I have an 07 xc90 3.2l and I’m not entirely positive but I think denso is the original supplier of spark plugs for this year model. The car does have the denso engine management system in it so that would make sense. Plug gap will be either .040 or .044. Either will work.
