Spark plug cable Baxi De Dietrich 7769840

The spark plug cable for Baxi boilers is a crucial part of the ignition system, delivering the high-voltage spark needed to ignite the gas burner. Over time, this cable can degrade due to heat and electrical stress, leading to ignition failures or intermittent operation. Replacing it with a genuine Baxi spark plug cable ensures a strong, consistent spark, helping your boiler start reliably every time. This component is ideal for technicians and homeowners performing ignition system repairs.
