HYUNDAI/DENSO (3478) FXU16HR11 IRIDIUM LONG LIFE SPARK PLUG
Iridium Long Life (SIP)
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.
