NGK BCPR7ES Spark Plug – Stock No. 3330
The NGK BCPR7ES is a reliable copper core spark plug with a projected tip and built-in resistor. It offers strong ignition performance and stable combustion, especially under higher loads and temperatures.
A heat range of 7 makes it a slightly colder option than many standard plugs. This can help reduce knock and pre-ignition in tuned or hard-driven engines. It is also suitable as a robust OE-style replacement in engines that specify this plug.
Why it matters
– Delivers a clean, consistent spark for smoother running and better throttle response.
– Colder heat rating can aid durability in performance use.
– Nickel alloy ground electrode balances service life and cost.
– Projected tip improves flame kernel location for reliable ignition.

Fitment guidance
Use this plug only in engines designed for a 14 mm thread, 19 mm reach, gasket seat plug with a projected tip and resistor. Many petrol engines from the 1990s-2000s use this form factor, including some naturally aspirated and turbo applications. Please use the site’s vehicle lookup to confirm fitment, or check the Vehicle Fitment tab for full details.
Important: Set the gap to the vehicle manufacturer’s specification. Do not exceed recommended torque.
