I have autolite plugs in the 289 with 45 printed on them. I have splitfire plugs in the 302 with SF 4E printed on them. My question is, are these plugs interchangable?(can I put the splitfires in the 289 and the autolites in the 302?)

TIA

Yes, in fact, I use SF4E Splitfires in my Mustang before I switched to the NGK Iridium plugs. The Autolite 45/46 spark plugs are fully interchangeable with SF4E
