Each coil mounts to the valve cover with the factory-style bolt pattern and electrical connector, so replacement is straightforward for DIYers and technicians. The kit ships as eight coils so you can refresh an entire bank or the full engine at once for even performance.\u003c\/p\u003e\n\n\u003ch3\u003eHow will these coils affect vehicle drivability?\u003c\/h3\u003e\n\u003cp\u003eReplacing worn or failing coils with ENA UF414 units helps eliminate intermittent misfires, improves throttle response, and reduces rough idle events caused by inconsistent spark.
