Use the correct plug and interval for the engine. Rough running needs diagnosis even when spark-plug service is due.

Service at our shop: 1325 Wickham Avenue, Mattituck, NY 11952

About this service

Spark plugs ignite the air-fuel mixture in spark-ignition engines. Plug design and the replacement interval vary, so engine identification and service history are important when planning the work.

NOFO distinguishes a scheduled plug change from a complaint such as misfiring or hard starting. Those symptoms can have other causes and may need testing first. Any related ignition findings or access requirements are explained before the repair scope is authorized.

Signs to have checked

The engine’s spark-plug replacement interval has arrived
Previous plug-service records are incomplete
Rough idle or hesitation that needs diagnosis
Hard starting or a misfire warning requiring evaluation

What the visit can involve

Confirmation of plug specification and the engine’s replacement requirements
Review of previous plug work and any reported misfire or starting symptoms

Common questions

Are more expensive spark plugs always the right choice?

Compatibility with the engine is what matters. The correct design and specification should guide the selection; a different material or marketing claim alone does not establish suitability.

Do new spark plugs always fix rough idle?

No. A rough idle can involve fuel, air, ignition or mechanical conditions. Tell the shop about the symptom so it can determine whether diagnostic testing is needed alongside scheduled service.
