I've been running the NGK since I'm pretty sure they are the OE manufacturer. Subaru is charging crack prices for those coils.
I would get NGK, Denso or Motorcraft coils though, you don't want to cheap out on critical parts like this.
I have NGK coils and plugs on my B14NEH. No issues at all.
Get a Denso or NGK coil. You can try an auto parts store coil (do NOT get one from Amazon) and if it solves it, order the Denso or NGK.
I use a BERU ZSE001 Ignition Coil, also in a '72. It's bomb-proof - zero starting issues after a lifetime (3 decades!) of bump-starting.
Only disadvantage is it doesn't like being left in the 'contact' position for long, which is not a problem for me.
Working well so far with accuspark dizzy and leads and no issues. I have one on my MorrisMini project as well and provides good spark.
I installed ngk coils originally and they lasted the longest ( around 8k miles before the first one went ).
NGKs product quality has diminished but a brand new set of 6 in and 2 of the six aren't working after about 2 months
NGK gave me troubles on one of our old LR3s
I just bought my son three coil on plug ignition coils with the NGK box but country of origin, China. I'm not happy with any Chinese crap.
