Welcome to Autograph BVS — a professional car repair service in Finestrat, Alicante. We offer a complete range of spark plug replacement and maintenance services using modern equipment and highly qualified specialists.

Spark plugs are critical components of gasoline engines responsible for igniting the fuel-air mixture. Their condition affects engine operation, economy, power, and fuel consumption. Our team in Finestrat is ready to diagnose, replace, and service your vehicle’s spark plugs quickly and professionally.

What are Spark Plugs?

Spark plugs are electrical devices that generate a spark to ignite the fuel-air mixture in an engine cylinder. This is one of the most important parts of a gasoline engine.

Main spark plug characteristics:

• Electrode — creates spark between electrodes
• Insulator — ceramic material isolating current
• Threading — attaches to cylinder head
• Gap — distance between electrodes (usually 0.8-1.5 mm)
• Electrode material — copper, nickel, platinum, or iridium
• Heat rating — determines thermal characteristics

Why do you need spark plug replacement?

• Ensure reliable engine starting
• Improve engine performance
• Reduce fuel consumption
• Lower harmful emissions
• Prevent engine misfires
• Increase engine lifespan
• Pass technical inspection (ITV)
