These are the only plugs we suggest for 2.3 turbo applications running stock TFI ignition. We've seen people have issues with other brands, as well as non-copper plugs (platinum, iridium, etc.) but these tried and true copper plugs just flat out work. No reason to spend big money on the "fancy" plugs when they will work no better (or in many cases will be much worse) than what Ford spec'd as the OEM plug for these engines.

These come factory gapped to .040". We suggest .028" gap for 15-22psi and .024" gap for 23+psi (race gas only). If you want us to gap them for you before shipment, the option is available below. Fits many other applications, see fitment guide below. 

Optional Motorcraft spark plug wires are also available. 

Sold as a set of 4.
