It uses platinum on both electrodes for consistent firing and long service life, with a 0.044 in. pre-gap and resistor design for stable ignition performance.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDouble platinum firing design for durable spark performance\u003c\/li\u003e\n\u003cli\u003ePlatinum center and ground electrode tips\u003c\/li\u003e\n\u003cli\u003e0.044 in. pre-gap for specified applications\u003c\/li\u003e\n\u003cli\u003eResistor spark plug with ceramic insulator\u003c\/li\u003e\n\u003cli\u003eTapered seat and 14 mm thread diameter\u003c\/li\u003e\n\u003cli\u003eFits Ford F-150, Ford Bronco, Chevrolet Camaro, and other listed applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDetailed Description\u003c\/h2\u003e\u003cp\u003eThe Autolite APP24 spark plug is engineered as an OE-form, fit, and function replacement for many Ford, Chevrolet, GMC, Buick, Pontiac, Cadillac, Jeep, and Isuzu applications. Its platinum-to-platinum firing design supports consistent ignition over extended service intervals, while the tapered ground electrode and mid-projection insulator help maintain reliable combustion characteristics. The APP24 part number is commonly searched by buyers looking for a direct replacement spark plug for Ford F-250, Chevrolet S10, and Pontiac Firebird applications.\u003c\/p\u003e\u003cp\u003eAutolite positions this Double Platinum Spark Plug line as a value-focused OE alternative for foreign and domestic vehicles. The APP24 combines a platinum center electrode, platinum ground electrode tip, nickel core ground electrode, and ceramic insulator in a standard regular center electrode design. This part cross-references Monroe Shocks \u0026amp; Struts (e.g., 41-817, 21020186) for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Is Used For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHard starting caused by worn spark plug electrodes\u003c\/li\u003e\n\u003cli\u003eMisfire concerns from excessive plug wear or gap growth\u003c\/li\u003e\n\u003cli\u003eReduced throttle response during acceleration\u003c\/li\u003e\n\u003cli\u003ePoor fuel economy related to weak ignition output\u003c\/li\u003e\n\u003cli\u003eRoutine ignition service on listed Ford, Chevrolet, and GMC platforms\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the vehicle application against the fitment list before installation. Several listed applications specify a 0.035 in. or 0.045 in. gap, so confirm the required gap for the exact vehicle and engine before use. The APP24 uses a tapered seat and stud terminal; match both to the original plug specification. The part number APP24 should be checked against the existing plug and service information for the vehicle.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eAutolite supplies ignition products to the automotive aftermarket and original equipment manufacturers, and this APP24 spark plug is built to OE form, fit, and function standards for the listed applications.
