Spark plugs to use with ecu?
Turbo Mini Forums

Well I fitted a polestar ECU and have been told that I need restricted spark plugs. I have been using B8ES for a while and have been happy with them. I've had a look on NGK website and was hoping for some B8es/r, but these don't exist.
Any suggestions??

BCR 8ES

Cheers Joe this is what I was looking for

Same as RS Turbos or RS Turbo fiesta etc

speed didn't kill me, but taxation probably will

I'm sure you can get the BP8 in an R.

A man without a project is like a like a woman without a shopping list.

P generally means projected nose, which in a cold plug like an 8 is less common.

Although there are other more expensive variants in 8 with a normal projected nose.

I used DCPR8E in the BMW K head engine when I ran the nitrous rather than the 6's. They still melted lol.

If I can do a bit of thread resurrection!

The miglia is running b9es , kad , med etc all list them as race plugs ! That’s ok but what about the resistor bit as the car runs an Ecu etc !


Thanks rick

if i'm not mistaken, the leads might be resisted? negating the need for resistor plugs.

Doesnt R just refer to resisitive and depends on what leads you are using?

I can confirm you will need Resistor plugs and leads, swapping in non resistor pugs on mine caused he ecu to start resetting and farting about.

Thanks joe ! Ive not found any in 9’s just 8’s !
Its been mapped on the engine dyno with the normal ones in !!
Seams strange

If it's been running fine with non resistor plugs already...then never worry about it.

But generally speaking you should be using resistor plugs as they can help reduce electronic interference.

Some setups wont matter, some will.
