NGK sparkplug - BPR6ES
This is the Resistor version of the very common BP6ES -
The BP6ES was used in many cars from the 60'sand 70's and this BPR6ES is compatible with those cars.
This resistor version is preferred for our Classic Fuel Injection systems and electronic ignition systems in general.
Part number = BPR6ES
Spanner Size = 20,8 mm
Thread Size = M14 x 1,25
Thread Length [mm] = 19
Unscrewable SAE connector
Nickel Middle Electrode
1 - Earthed Electrode
Spark Plug Interference Suppression = 5 kOhm resistor
Spark Plug = with gasket seat
Spark Position [mm] = 3
Before buying please check that these will fit your car - there are numerous cross reference websites to refer to
( probably search for the BP6ES as they were fitted at the time where as this resistor version is a later option often not specified )
