Keep reading these key things to know about replacing your car’s spark plugs, from when to do it to mistakes to avoid.
First, drivers should understand the signs it’s time to replace their vehicle’s plugs. If your car’s engine is running rough, misfiring, or having trouble starting, it’s time to check those spark plugs.
Other telltale signs include poor fuel economy, sluggish acceleration, and unusual engine noises. Don’t ignore these symptoms; addressing them early can prevent more severe issues down the road.

Another thing to know about replacing your car’s spark plugs is the tools you’ll need! Get your spark plug socket, ratchet wrench, and gap gauge. A torque wrench will also help you tighten the spark plugs to the manufacturer’s specifications.
Disconnect the battery before beginning the replacement process to prevent any electrical mishaps. Work in a ventilated area, and wear gloves and safety glasses to protect yourself.
Finally, you should avoid common mistakes during the replacement process. Over-tightening or under-tightening the plugs can damage the threads or lead to performance issues. Always use a torque wrench to apply the ideal force.
Another frequent error is neglecting to check and adjust the gap size, which can negatively affect the spark plug’s performance. Using an anti-seize compound on the threads can prevent future removal difficulties, but use it sparingly to avoid contamination. Finally, ensure the engine is cool before starting the job to avoid burning yourself or damaging any components.
