Replacing worn ignition coils while leaving old spark plugs in place—or vice versa—forces the new components to work twice as hard, leading to premature failure and persistent P0300 to P0308 misfire codes. This official 8-piece DG511 + SP546 ignition kit is matched exactly to your truck's factory resistance and heat range specifications. By replacing all 8 plugs and coils simultaneously with genuine Ford parts, you guarantee uniform combustion across all cylinders, preventing stress on the catalytic converter and maximizing your engine's operational lifespan.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"4\"\u003e🆚 OEM MOTORCRAFT vs CHEAP AFTERMARKET\u003c\/h3\u003e\n\u003cp data-path-to-node=\"5\"\u003eWhen it comes to the highly sensitive Ford 3-valve modular engines, generic aftermarket parts often fail within months due to inferior thermal management and slight variances in electrical resistance.
