Can anyone advise on which ignition leads I should fit as a standard replacement. I'm not sure of the OEM manufacturer but don't feel like paying over £100 on a brand I've never heard of from GSF...

Any advise appreciated, thanks.

Sorry I was missing key info... M20B25 in a pre-facelift car.

Thanks

Short answer is I wouldn't buy new. Plenty of second hand original ones around in mint condition.
Ignition leads aren't a service item on E30s like they were with those on inferior makes from the same era.

So you'd suggest second hand from eBay or the like? I was really hoping to get new, but considering what you have said I'll have a look about for used.

Thanks

Try one of the traders on here. Why are you changing them in the first place?

Main reason was due to them not having been changed, but since you mentioned they are not a service item I may leave them.

My concern was added due to a bit of a lumpy idle from cold. I've checked the blue temp sensor resistance and all seems good...

the wires do not last forever but OEM last a good amount of time and many aftermarket ones are scrap . if there are no issues with the running or cracks in the insulation etc leave it be.

The usual combination of worn injectors and minor air leaks probably.

Thanks guys,

I'll have a check for cracks etc. and call it a day with the ignition leads then.

I've had a good look around for air leaks previously, but injectors have been on my list of things to do for a while. When the car gets a week or so of down time I'll send them off :D
