The platinum needle tip ground electrode promotes higher spark energy and reduces heat quenching.

Engineered to endure extreme temperatures, this spark plug is built to last up to three times longer than conventional plugs, providing sustained spark performance for over 100,000 miles. Its construction includes 360-degree laser welding for a robust bond and structural integrity, meeting high standards for durability, emissions, and performance.

The Denso FK20HR11 spark plug offers enhanced longevity and performance, making it a popular choice for many vehicles. This plug features a 0.7mm iridium-tipped, laser-welded fine wire center electrode, paired with a platinum-tipped ground electrode, designed for optimal combustion and extended service life. Constructed with a purified alumina powder insulator, the FK20HR11 provides exceptional strength and thermal conductivity. Its five-rib design prevents flashover, ensuring consistent spark delivery. This Denso spark plug is 100% pre-fired to guarantee the highest quality. Its specifications include a 14mm thread diameter, 1.25mm thread pitch, gasket seat type, 26.5mm reach, and a 5/8" hex size. The center electrode is projected, with a fine wire design, while the ground electrode is also fine wire for efficient spark transfer. It operates as a resistor-type plug with a value of 5k Ohm. Denso iridium long-life spark plugs are often factory-installed on luxury vehicles by major automakers like GM, Toyota, Honda, and Mitsubishi. This particular plug has an estimated longevity of 80,000 to 100,000 miles.
