If you’ve got a Dodge Charger, especially one with a V8 engine like the 5.7L HEMI or 6.4L SRT, you’ll want to plan on changing the spark plugs every 60,000 miles or so. These V8 beasts tend to go through plugs a bit faster, especially if you drive hard or have modified your Charger for performance. However, if you’ve got the V6 (3.6L Pentastar), you might get a little more life out of them—usually closer to 80,000 miles.
That said, don’t just go by the mileage alone. If you notice your Charger starting to idle rough, losing power, or misfiring, those are solid signs it’s time to replace the plugs sooner rather than later. V8 owners, especially, might notice these symptoms quicker due to the higher demands placed on the engine. If you’re really pushing your Charger with high speeds or aggressive driving, you might want to swap them out before you hit that 60,000-mile mark to keep everything running smooth.
Also, don’t forget, the V8 engines have 16 spark plugs (two per cylinder), so keep that in mind when budgeting for replacements. It’s not a super difficult job, but if you’re doing it yourself, make sure you have the right tools and a bit of patience—it can be time-consuming.
