Spark Plugs & Ignition System
Good combustion requires strong, reliable spark. Check:
Spark plugs are healthy and gapped correctly
Replace them if they’ve done over 20,000 miles (or sooner for turbo cars)
Use colder plugs if your vehicle requires it for higher boost setups (we can advise)
Ensure ignition coils aren’t breaking down under load (common in VAG and Ford ST/RS platforms)
