My 1984 323 (2.7L M20) has developed a surge around 2500 - 3000 rpm. Irecently replaced the primary fuel pump because it went south, so fuel pressure is quite nice, however this did not solve the surge I was getting.
I am planning to replace the leads as this symptom can be caused by them. Does anyone have recommendations on what leads to go for. I track this car so leads that resist breakdown due to heat etc would be good.

TBH I'd go std leads everytime, they last a good 100K normally without issue, good enough for BMW, good enough for me
As for "performance" leads, is there such a thing, not seen any evidence to support the claims of the makers, the magnecor set I had on my S12 fell apart within weeks due to poor quality

If you hang around the LPG discussion groups on the net, you learn all about ignition leads, as LPG puts extra demands on ignition components, and a single subsequent backfire can cause expensive damage.
The OE ignition leads on my wife's LPG 325 M20 are over 200,00 miles old and are in perfect condition.
Landrovers , however, can get through a set of OE leads in about 20-30,000 miles, and anyone running one of these on LPG without using something like Magnecor is taking a risk.
If it says BMW on the box, then they ARE high performance
