Yes, a dirty air filter and weak ignition coil can affect the performance of spark plugs:

Dirty Air Filter: If the air filter is clogged, it can restrict airflow into the engine, causing the engine to run rich too much fuel relative to air. This can lead to carbon buildup on the spark plugs, reducing their efficiency.
Weak Ignition Coil: The ignition coil provides the necessary voltage to the spark plugs. If the coil is weak o r failing, the spark plug won’t generate a strong enough spark to ignite the air-fuel mixture, leading to misfires, rough idling, and poor performance.

Camry owners should regularly check the air filter and ignition coil and replace them as necessary to prevent spark plug issues.
