Description:
The Autolite APP5363 Double Platinum Spark Plug is engineered to deliver dependable ignition performance, reduced misfires, and extended spark plug life. Featuring a platinum-to-platinum firing design, this spark plug uses platinum pads on both the center and ground electrodes to help minimize gap erosion and maintain consistent spark delivery over time.
The copper core center electrode improves heat transfer, helping the plug maintain proper operating temperature while reducing the risk of fouling. A yttrium-enhanced ground electrode increases durability under high heat and pressure, making this spark plug ideal for distributorless ignition system (DIS) engines. The high alumina ceramic insulator provides excellent dielectric strength and thermal conductivity, while the multi-rib insulator design helps prevent flash-over for reliable ignition performance.
Autolite double platinum spark plugs provide long-lasting performance and reliable engine operation across a wide range of gasoline engine applications.
