@fawaazhelli: Left spark plug vs Right spark plug 🔥 Watch what happens when the engine starts: Oil sprays through the valves → the good spark plug (right) fires perfectly, producing clean combustion. The bad spark plug (left) struggles — weak sparks, misfire, uncontrolled fire, and thick black smoke. One small part makes all the difference between smooth performance and expensive engine damage. Always replace your spark plugs on time! #mechanic #trending #fyp #foryou #tiktokgrowthchallenge
