NGK D8EA Spark Plug, 12mm Thread, 3/4" Reach, Copper Core
Are you looking for a high-performance spark plug that delivers reliable ignition and durability for your Volkswagen air-cooled engine? If so, you might want to consider the NGK D8EA spark plug, compatible with Volkswagen air-cooled engines with 12mm spark plug threads.
A spark plug is a device that creates a spark to ignite the air-fuel mixture in the combustion chamber of your engine. The quality and condition of your spark plug can affect the performance and efficiency of your engine, as well as its emissions and lifespan. Therefore, it is important to choose a spark plug that suits your engine’s needs and specifications.
The NGK D8EA spark plug is a good choice for hot-running engines, as it is two heat ranges colder than the stock spark plug. This means it can dissipate more heat and prevent pre-ignition and detonation, which are harmful conditions that can damage your engine. However, it may not be suitable for cold climates or low-compression engines, as it may cause fouling or poor starting.
The NGK D8EA spark plug features a copper core electrode that provides better conductivity and heat dissipation than other materials. It also has a trivalent metal plating that resists corrosion and seizing, which can cause poor performance or engine failure. The spark plug has a conventional tip, which is less expensive and provides more piston clearance than a projected tip. However, a conventional tip may also shroud the spark and reduce the flame kernel, resulting in less power and efficiency. A projected tip may offer better performance and fuel economy, but it may also interfere with the piston or valves if the engine has a high compression ratio or a modified camshaft.
The NGK D8EA spark plug is compatible with various Volkswagen models such as the 411, 412, and late Bus that use the Type 4 engine. This engine was used in models from 1968 to 1979 and has 12mm spark plug threads. The Type 4 engine is known for its increased displacement, power, and torque compared to the previous Type 1 engine. However, it also runs hotter and requires more cooling and lubrication. Therefore, using a suitable spark plug like the NGK D8EA can help improve the performance and reliability of your Type 4 engine.
