Service Videos

Spark plugs may be small, but they make every start, idle, and acceleration possible. This service video explains how each plug creates the spark that ignites the air-fuel mixture inside the cylinder.

A spark plug creates the electric spark that starts combustion in a gasoline engine so the piston can produce power.

Over time, the center electrode and ground electrode wear down. As the spark plug gap grows wider, the spark can weaken and cause hard starting, rough idle, engine misfires, poor acceleration, or lower fuel economy.

In Orlando, FL, searing pavement temperatures, dense humidity, and standing water from summer storms can make ignition problems show up faster. Heat places more stress on engine parts, while moisture around ignition boots or coils can make a weak spark more noticeable under load.

Drivers on US-192 and State Road 408 often deal with stop-and-go traffic, hot restarts, and quick highway acceleration. Luxury commuter sedans, high-performance sports cars, and premium family SUVs need the correct plug type and gap to keep combustion smooth.

If your check engine light is on, your vehicle shakes at idle, or acceleration feels uneven, spark plugs may be part of the issue. Many mileage-based ignition checks fit naturally into scheduled factory maintenance for European and exotic vehicles.
