Together they replace worn OEM parts (replaces #5C1074, 4503 and equivalent numbers) to reduce misfires, improve throttle response, and help maintain fuel economy when installed to the correct fitment. Each component is produced under TS16949-certified processes and factory-tested to meet fit and function requirements for the listed vehicles.\u003c\/p\u003e\n\n\u003ch3\u003eHow will these coils and plugs improve my car's starting and idle?\u003c\/h3\u003e\n\u003cp\u003eStronger, more consistent spark energy reduces misfires during cold starts and at idle.
