DENSO 3113 Double Platinum Spark Plug PQ20R-P8

The DENSO 3113 is a premium double platinum spark plug engineered to deliver exceptional performance, durability, and extended service life. Unlike conventional platinum plugs that feature platinum on only the center electrode, this plug utilizes platinum on both the center and ground electrodes, providing superior resistance to erosion and corrosion for reliable ignition performance.

Key Features:

• Double platinum construction with platinum-tipped center and ground electrodes for extended service life in excess of 60,000 miles
• 14mm thread size with 19mm thread reach and flat gasket seat design
• 0.8mm preset gap for optimal spark performance
• Copper core center electrode for excellent thermal conductivity
• 5000 Ohm resistor value to prevent electromagnetic interference
• Machine-rolled threads prevent cross-threading and seizing during installation and removal
• Five-rib purified alumina powder insulator provides exceptional strength and prevents flashover
• 100% pre-fired at the factory to ensure highest quality
• 360-degree laser welding and copper-glass seal for gas-tight performance

Manufactured to strict OE performance and emissions standards, this DENSO spark plug is precision-engineered for reliable first-time fit and long-lasting performance. The 16mm hex size design allows for easy installation. Cross-references to Toyota OEM part number 90919-01145 and alternate DENSO part number PQ20R-P8.
