NGK BP7ES Spark Plug - 14mm Thread (Long Reach)

The NGK BP7ES is a cold-range long-reach spark plug designed specifically for turbocharged, high-compression, or competition air-cooled Volkswagen engines. It is commonly used in race-prepared Beetles, Karmann Ghias, Buggies, and high-output Type 1, Type 2, and Type 3 engines fitted with aftermarket cylinder heads requiring a 14mm thread and 19mm reach.

The colder heat range (7) enables the plug to operate efficiently under extreme combustion temperatures, helping to prevent pre-ignition and detonation in engines producing significantly more heat than standard. This makes the BP7ES the preferred choice for turbo, nitrous, or heavily tuned naturally-aspirated VW engines.

Featuring NGK’s projected insulator design (P), this plug improves combustion efficiency and throttle response by positioning the spark deeper into the combustion chamber. The copper-core electrode ensures excellent heat transfer and a strong, consistent spark, while the standard design (S) ensures durability and easy installation.

Built to NGK’s world-renowned standards, the BP7ES offers long-lasting reliability, stable idle characteristics, and consistent performance even in the harshest racing or off-road environments.
