Iridium Spark Plugs

Designed to operate over a much wider heat range than ordinary plugs

Resists carbon buildup and pre-ignition

Copper Plus - Dependable Performance and Durability

Copper core center electrode allows for accurate control of heat range for longer life

Inhibits corrosion

Extreme performance upgrade via OEM spark plugs and provide a lifetime at 40,000 50,000 miles.

Plugs have a fine-wire Iridium center electrode and nickel-alloy terrain electrodes for maximum engine and torque.

Designed for fuel-injected and turbo engines.

DENSOs revolutionary Twin-Tip design is a combination of highly durable precious metals-Platinum and Titanium.

The center electrode is created using an extremely durable platinum alloy that allows for the reduction of the tip size to 1.1mm in diameter, while maintaining the life of the plug.

The Titanium-enhanced alloy on the ground electrode also increases durability, which is critical to minimize tip erosion and achieve the new Twin-Tip design

This 6 pack DENSO 3194 Spark Plug replaces DENSO Auto Parts K16TR11, Toyota 94859009, Toyota 94856823, Toyota 90919-01192, parts and is perfect for replacement or a performance upgrade.

REDUCE EMISSIONS AND MISFIRES: The patented DENSO Spark Plug enables complete fuel ignition in the combustion chamber. It virtually eliminates erratic starts caused by poor fuel mixtures and excessive soot buildup. The DENSO Spark Plug employs a unique ground electrode designed to generate a larger spark nucleus at the point of ignition. Greater spark energy means improved flame travel, producing more complete, consistent, and efficient combustion

GAIN GREATER FUEL EFFICIENCY: This DENSO Spark Plug fires leaner mixtures than conventional plugs and improves throttle response. Its ground electrode was developed to improve ignitability for increased efficiency in emission gas purification and fuel consumption. The DENSO Spark Plug is 100 percent pre-fired to ensure reliable operation and lasts twice as long as conventional plugs. The unique five-rib insulator reduces flashover and decreases voltage loss

【Precautions for Purchase】:Please confirm the compatibility according to the year/make/model of your vehicle and the OE number of the replaceable part.

【Iridium Spark Plug Features】:The BDFHYK Iridium Spark Plug offers superior ignition performance and longer service life, with a very fine iridium tip that provides a stable idle and enables fast starting and acceleration. Excellent resistance to fouling and damage, minimizing fuel consumption and exhaust emissions.
