Hi!!! Today I changed the Spark Plugs on my 1982 Regal with the 267ci ( 4.4l ) V8! I installed: ACDelco R45TS! Are they the right ones for this engine? Thank`s for answers Niki
Niki, R45 TS is the right plug, you can also use Champion RV19YC, Autolite 26, or Bosch 7586, take your pick.
Would a R45TS be good for a stock 1971 455 or would the factory R44TS plugs be the better choice? Thanks
