If your diesel is hard to start in cold weather, cranks longer than it used to before firing, or is throwing a glow plug circuit code, this set replaces all 8 plugs at once.\u003c\/p\u003e\n\n\u003ch2\u003eWhy the F-350 and Econoline Share This Glow Plug\u003c\/h2\u003e\n\u003cp\u003eFord used the 7.3L IDI (indirect injection) diesel V8 across its heavy-duty truck and van lineup during this era, including the F-350 pickup and the E-350 and E-250 Econoline vans, since sharing one diesel engine platform across multiple body styles was more efficient than developing separate engines for each. That shared engine is why one glow plug, cross-referenced to the same OE numbers, covers pickups and full-size vans alike instead of requiring a different part for each vehicle type.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCross-referenced to OE numbers F2TZ12A342A and E4TZ12A342A\u003c\/li\u003e\n\u003cli\u003eComplete set of 8, enough for all cylinders on the 7.3L IDI V8\u003c\/li\u003e\n\u003cli\u003eBuilt for reliable cold-weather starting performance\u003c\/li\u003e\n\u003cli\u003eDirect-fit replacement, no modification required\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: Diesel glow plug\u003c\/li\u003e\n\u003cli\u003eOE\/OEM numbers: 0250202254, 5614220, E4TZ12A342A, E7TZ12A342A, F2TZ12A342A, ZD9\u003c\/li\u003e\n\u003cli\u003eInterchange numbers: F2TZ12A342A, E2TZ12A342A, E4TZ12A342A, E7TZ12A342A, 1819649C1\u003c\/li\u003e\n\u003cli\u003eQuantity: 8 plugs\u003c\/li\u003e\n\u003cli\u003eCondition: New\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eFits the 1988-1994 Ford F-350, 1988-1994 Ford E-350 Econoline, and 1988-1993 Ford E-250 Econoline, all with the 7.3L IDI diesel V8. Because Ford offered both gasoline and diesel engine options across these truck and van lines during this era, it's worth confirming your specific vehicle has the 7.3L IDI diesel before ordering, since a gas engine or the later 7.3L Power Stroke direct-injection engine uses different glow plugs entirely.\u003c\/p\u003e\n\n\u003ch2\u003eSigns Your Glow Plugs Need Replacing\u003c\/h2\u003e\n\u003cp\u003eFailing glow plugs on an IDI diesel typically show up as noticeably harder cold starts, longer cranking time before the engine fires, white smoke from the exhaust right after starting in cold weather, or a rough idle that smooths out once the engine warms up. Because glow plugs heat the combustion chamber to help ignite diesel fuel before the engine reaches full operating temperature, a weak or failed plug mainly affects starting and warm-up behavior rather than how the engine runs once it's already warm.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Replace the Complete Set\u003c\/h2\u003e\n\u003cp\u003eGlow plugs on a given engine are installed and used together, so when one has failed from age and heat cycling, the rest have typically seen the same years of service and are not far behind. Replacing all 8 at once rather than testing and swapping individual plugs one at a time means consistent, even heating across all cylinders during cold starts, rather than dealing with an uneven start caused by mixing old and new plugs.\u003c\/p\u003e\n\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eReplacing glow plugs on the 7.3L IDI means locating each plug along the side of the cylinder heads, disconnecting the glow plug wiring harness, and removing each plug with a glow plug socket before threading in the new ones. Because these plugs have been in place for decades on an older diesel, penetrating oil ahead of time is worth using to avoid a plug breaking off in the cylinder head, which turns a simple swap into a much larger repair.\u003c\/p\u003e\n\n\u003ch2\u003eOrdering Information\u003c\/h2\u003e\n\u003cp\u003eThis glow plug set is in stock and ships ready to install.
