Looking for some spark plug advice. Engine is a 5.0 GXI-B. The manual calls for 2 sets of part #21467472. I've seen chatter online that says these are Champion plugs and can be purchased or cross referenced to something different and cheaper, or better (Iridium). Is this so? Looking to save a buck if it makes sense, or get a better plug.
