DENSO(3421) SK20HR11 IRIDIUM LONG LIFE SPARK PLUG
| Iridium Long Life |
| DENSO's patented Iridium alloy is more durable than even Platinum, allowing the center electrode to be shrunk to only 0.7 mm in diameter. This produces a dramatic improvement in ignitability and spark plug life. DENSO's Iridium Long Life spark plug is standard equipment with a number of automakers including GM, Toyota, Honda, and Mitsubishi.
