DENSO 3312 XU24EPR-U U-Groove Nickel Spark Plug

The DENSO 3312 (XU24EPR-U) is a high-performance nickel spark plug engineered with DENSO's patented U-Groove technology for superior ignition performance. The U-shaped groove in the ground electrode gives the flame a groove to grow in, resulting in less flame dissipation and a larger flame front for a more complete combustion. This translates to better fuel efficiency and improved throttle response.

Key Features:

• Copper core for better thermal conductivity
• Purified alumina powder insulator provides exceptional strength and thermal conductivity
• Five rib insulator prevents flashover
• Machine rolled threads prevent seizing or cross threading during installation and removal
• 100% pre-fired to assure the highest quality possible
• Copper-glass seal bonds center electrode and insulator for a gas-tight seal
• Nickel alloy electrode tip for reliable performance
• Resistor type for reduced electromagnetic interference
