This part cross-references Mitsubishi MD338991 and Porsche P22PR8 for the same application.

What This Spark Plug Helps Address

• Hard starting caused by worn or fouled spark plugs
• Rough idle from inconsistent ignition output
• Misfire conditions related to degraded plug electrodes
• Reduced throttle response from weak spark delivery
• Maintenance replacement for OE-style ignition service

Installation Notes

Verify engine application before installation and confirm the specified gap for your vehicle. Listed fitments include 0.028-inch gap requirements for Maserati Spyder, Maserati 228i, Maserati 425, Maserati Biturbo, and Porsche 944 applications, while Lamborghini Countach and Mercedes-Benz 300SL listings specify a 0.025-inch gap. Use the correct torque procedure for the cylinder head material and inspect ignition wires, coils, and boots during service.
