To find the right spark plug:
1. Locate your engine's displacement: This is usually printed on a sticker under the hood or in your owner's manual. Common E250 engines include 4.2L V6, 4.6L V8, 5.4L V8, and 7.3L V8.
2. Consult your owner's manual: This will specify the exact spark plug type recommended by Ford. The manual will list the manufacturer, part number, and heat range.
3. Check a reliable parts website: Once you know the engine displacement, use a parts website like AutoZone, Advance Auto Parts, or Napa Auto Parts. Enter your vehicle's year, make, model, and engine size to find compatible spark plugs. They will also often list popular alternatives.
4. Consider the quality: While OEM (Original Equipment Manufacturer) plugs are a safe bet, reputable aftermarket brands like Bosch, NGK, Champion, and Autolite offer high-quality alternatives that often perform equally well or better, at a lower cost. Look for reviews to compare options.
Once you have the correct part number from your owner's manual or parts website, that's the best spark plug for *your* 2000 Ford E250. Don't just rely on general recommendations; the wrong spark plug can damage your engine.
