Review on πŸ”₯ Enhance Engine Performance with the Motorcraft SP542 Spark Plug by Vedprakash Trilltight

Revainrating 3 out of 5

Just not SP-542! good for spare parts

I ordered these and received SP-578 which is a connector for SP-542. SP-542 has a heat range of 7, which translates to a heat range of 8 (smaller heat range, better performance). While they are compatible, they are not the same connector. OEM number shows SP-578 in description, listing needs to be updated to SP-578!

Pros
  • This is amazing
Cons
  • Negative impression
