When you do your 60k, you need to replace your spark plugs. The original Ford design has been discontinued. If you want an upgrade over the Autolite double platinum plugs (the closest to the factory design), these Irridium plugs are a great choice. These plugs will fit and perform well in a SHO, and irridium plugs are know for a better spark and longer life. We do not recommend irridium plugs in cars with superchargers, turbochargers or nitrous oxide (we recommend copper plugs for these applications).
Includes 6 Irridium Plugs.
1989-1995 SHO MTX
