The Bosch FR6DC+ is a standard copper core spark plug designed for everyday petrol engine use, offering reliable ignition performance and strong heat transfer characteristics. It’s part of Bosch’s nickel copper (“Super Plus”) plug range, combining yttrium enhanced nickel copper materials with tried and true Bosch engineering quality.
Key Features & Benefits:
• Yttrium enhanced nickel copper center electrode — increases durability and wear resistance compared with basic copper plugs.
• Copper core for excellent heat transfer — helps dissipate combustion heat effectively, reducing the risk of pre ignition and carbon buildup.
• Built in metal glass fused resistor — maximizes suppression of electrical interference with electronics like radios and ECUs.
• Ribbed insulator design — minimizes flash over misfires by increasing the insulator’s creepage path.
• Nickel plated rolled threads — protect against corrosion and make installation/removal easier without needing anti seize.
• Meets or exceeds OE specifications — engineered to match factory spark plug fit and performance for engines requiring this part.
Typical Use:
This plug is ideal as a direct replacement in many petrol engines that specify FR6DC (or similar heat range) and benefit from a standard grade spark plug with improved life and reliability over older basic copper designs.
