NGK BP5EFS Spark Plug – Stock No. 3712
This NGK BP5EFS is a standard nickel spark plug with a projected tip and long reach. It gives reliable cold starts, smooth idle, and stable combustion. It suits everyday driving and light performance use where a non-resistor plug is specified.
Use it when you want consistent ignition without going to fine-wire iridium or platinum. It is a good match for many older petrol engines that use a 14 mm, 19 mm reach, gasket-seat plug with a projected insulator and no resistor. Always confirm fitment with the vehicle lookup or the Vehicle Fitment tab.
- Stable spark under load for clean throttle response
- Projected tip helps efficient combustion and reduces fouling
- Non-resistor design for strong spark where RFI is not a concern
Check your engine’s required heat range, reach, and gap before installation.

For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.
Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.
Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
