Ignition leads for E30 318is M42

You'd be better off posting on the 3-Series forum.

To answer your question, I would be very suspicous of suspecting the M42 leads of a fault as they have proven to be very robust from all my experience - actually, other than physical damage (e.g. chaffing), I've never heard of them failing. If you must replace them, then go BMW - they may be expensive but they will last.

Just like to add, I've also bought lead set from GSF, and they were the made by the same manufacturer as the originals (beru), they even came with the pulse lead and sensor, and the clip to keep all the cables tidy...so I wouldn't put people off GSF/ECP, but check first who manufactures the parts, only things I've had bad experieces with are suspension parts, ARB drop links that lasted 9 months!!
