Description

TOYOTA GENUINE FK16HR11 SPARK PLUG (4PCS)

Toyota Genuine FK16HR11 features the distributor-less Toyota Direct Ignition System (TDI). Introduced in 1994, this system promotes greater combustion efficiency by firing the spark plugs twice as often as a standard ignition. With that in mind, the ideal spa plug for TDI-equipped Toyotas is the Dual-Ground Electrode design, which delivers optimum performance and durability -maintaining the originally recommended change interval.

Features

• Platinum on both the center and ground electrodes reduces wear
• Raised design provides excellent ignitability for a strong spark, smooth idle, and optimum performance.
• Platinum material also incorporates nickel and iridium, resulting in a stronger, more durable alloy that resists cracking.
• A smaller center electrode promotes higher firing performance.
• Iridium is a more durable material than platinum (its melting point is approximately 1200°F higher than platinum)
