PRODUCT OVERVIEW
Set of 4 Denso Iridium TT spark plugs designed for Mercedes C200 1.8L M271 engines (chassis CL203, S203, W203, model years 2002–2007). Engineered for improved ignition efficiency, acceleration, fuel economy and long service life.
KEY FEATURES
- Denso Iridium TT (Twin Tip) series spark plugs
- 0.4 mm ultra-fine iridium center electrode for high ignitability
- 0.7 mm needle-shaped platinum ground electrode to reduce quenching
- Built-in monolithic resistor to minimize electromagnetic interference
- 360° all-around laser-welded iridium tip for strength and durability
- Optimized design for stable combustion, easier starting and responsive acceleration
TECHNOLOGY & PERFORMANCE
The ultra-fine 0.4 mm iridium center electrode concentrates electric potential at the tip, lowering required spark voltage and improving ignitability under various driving conditions. Combined with the 0.7 mm platinum ground electrode, the twin-tip configuration reduces quenching effect, allowing faster flame kernel growth and more complete combustion. This helps extract maximum engine power while supporting better fuel efficiency and reduced misfires.
The 360° laser-welded iridium tip and high-melting-point iridium alloy ensure excellent wear resistance, enabling extended service intervals compared with conventional spark plugs.
