Spark Plug, WR8AC, 14 x 12.7mm, Bosch

Bosch Super Spark Plug has a Heavy Duty Yttrium-Enhanced Center Electrode with Copper Core Provides Superior Reliability and Durability. Tapered Cut Nickel Chromium Ground Electrode Assists in Cold Weather Starts and Provides Increased Ignitability. Nickel-Plated Rolled Threads Provide Anti-Seize and Corrosion Protection. Metal Glass Fused Resistor Gives Maximum Interference Suppression. Angular, 5-Rib Insulator Design Prevents Flashover. 

Installation Note: Original VW factory heads were 14 x 12.7mm "Short Reach", However over the years some repaired heads were converted to a 19mm "Long Reach" for better reliability. Please verify your cylinder head configuration and spark plug requirements before ordering. Bosch indicates the heat range of the spark plug in the middle of the plug number. For example, WR7AC has a heat range of 7. Bosch spark plugs are colder the lower the number, hotter the higher the number.
