Motorcraft SP-450
Copper core spark plug for classic gasoline engines requiring the SP-450 specification.
Motorcraft SP-450 is a copper core spark plug for selected classic gasoline engines. For spark plugs, the plug number, thread, reach and heat range must be checked more carefully than vehicle make alone.
Application / fitment
SP-450 appears in selected Buick, Chevrolet, Dodge, Ford, GMC, Lincoln, Mercury, Oldsmobile, Plymouth and Pontiac applications. Coverage includes Ford 5.0 / 302, 5.8 / 351C / 351M / 351W and 7.5 / 460, plus selected GM 5.0 / 305, 5.7 / 350, 7.4 / 454 and 7.5 / 455 engines.
