When I bought my car it had a set of new 'blue print' brand HT leads (99MY with manifod maunted coil pack, not plug top coils!), its since slowly developed a misfire between 2k and 3k rpm when on boost (off boost its OK), this clears above 3K where the stock mapping is a bit richer, misfire feels very 'ignition based' as it comes and goes very quickly, anyway its service time so I'm going to replace the stock plugs with some Iridium and want to replace the HT leads so what are the recommendations on here?

Stock Subaru
Magnecor (7mm, 8mm or 85kV)
Somthing else....

The O/E Subaru leads are very good and probably better than many of the aftermarket offerings.

 

Thanks Harvey, that is what I had heard, anyone else want to add a ten penneth?
