Using low-quality o r counterfeit spark plugs can lead to several issues:

Poor Engine Performance: Cheap spark plugs may not fire properly, leading to poor acceleration, misfires, and reduced engine performance.
Increased Emissions: Counterfeit plugs might not regulate fuel combustion as efficiently, leading to higher emissions and potential damage to the catalytic converter.
Shorter Lifespan: Fake o r subpar spark plugs tend to wear out much faster than genuine parts, causing more frequent replacements.

How to Verify Genuine Spark Plugs:

Always buy spark plugs from authorized dealerships o r trusted auto parts stores.
NGK and Denso are the leading brands recommended by Toyota, so ensure you purchase from a reliable source.
