MALIBU Spark ⚡️ Plugs

[Dezimade]

Hi there. I wanted to Get the best spark plugs out there for my 267 4 barrel V8

What are some of your suggestions as I have been noticing a hard start. As everything else is new? Thanks Dez

Completely stock engine w/cast iron heads... standard replacement AC DELCO R45TS will do.
