4Pcs Glow Plug 32A66-03102 for Mitsubishi Engine S4L S4L2 S4Q-2 S4S S4Q2 K4N K4A K4B K4C K4D K4E K4F

This fuel injector is a direct replacement unit designed for Mitsubishi Engine S4L S4L2 S4Q-2 S4S S4Q2 K4N K4A K4B K4C K4D K4E K4F. It delivers a precise atomized fuel spray into the combustion chamber for efficient burning. When an injector fails, the affected cylinder runs lean — or doesn’t fire at all — which puts extra stress on the remaining injectors and can damage the catalytic converter over time.

Signs You Need a Replacement

If your equipment is showing any of these symptoms, the injectors & nozzle may be the cause:

• Black or gray exhaust smoke — especially noticeable under load or acceleration
• Rough or uneven idle — the engine shakes or vibrates at low RPM
• Engine misfire or hesitation — stumbling when you step on the throttle
• Poor fuel economy — filling up more often for the same work
• Knocking or nailing sound — metallic noise from the engine under load
• Fuel smell in engine oil — diesel leaking past the injector seat into the crankcase

Replace as a Set

Replacing injectors as a set is the standard practice. Mixing old and new injectors creates uneven spray patterns — the new unit works harder and burns out faster. On multi-cylinder engines, a single failing injector can reduce total output by 20 to 30 percent. When you pull the old injectors, inspect the seats and copper sealing washers. If the seats are pitted or the washers are crushed, replace them before installing the new units.

Frequently Asked Questions

Which Mitsubishi models does this part fit?
Refer to the Vehicle Compatibility table above for the full list of Mitsubishi models. Each listing includes the body type, engine, and production years. Match your vehicle’s engine code (stamped on the engine block) against the listed codes to confirm.

Can I cross-reference 32A66-03102 with 32A6603102?
Yes. Both 32A66-03102 and 32A6603102 are interchangeable OEM numbers for this part. They refer to the same component with the same specifications, just different part number revisions. This replacement fits all applications listed for either number.

How do I check if my engine code (JP65, MT160D, MT180, MT180H) matches?
The engine code is stamped on a metal tag attached to the engine block, usually near the timing belt cover or on the cylinder head. Compare the code you find with the list above. Engine codes are 3 to 6 characters long and use a combination of letters and numbers.

This listing is for 4 pieces — do I need to buy a full set?
This listing includes 4 units. For best results, replace all injectors at the same time rather than one at a time. Mixing old and new units causes uneven fuel delivery and shortens the life of the new parts. If you only need a single replacement, check our other listings for individual units.
