Show original supplier description
The Motorcraft SP-435 is an engineered spark plug that delivers the original equipment (OE) fit and function required for Ford and Lincoln models. As the same part installed when the engine rolled off the assembly line, it guarantees a perfect fit and optimal performance, making it an ideal choice for maintaining your vehicle's efficiency and reliability. Constructed with a copper core center electrode and an Inconel electrode core, this spark plug is built for durability and consistent performance. It features a standard insulator type, a fixed terminal top, and a tapered seat type for a secure fit. The specifications include a 13/16 inch hex size, a .468 inch reach, and an 18 mm thread diameter, with a manufacturer heat range of 5. The spark plug is also a resistor type, which helps to reduce electromagnetic interference.
