Ignition coil NGK or APR

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.

Not sure if this would matter but I did replace the coils with APR ones, from the stock ones, when I redid the valve cover seal. It has an APR stage 1 tune and and APR air intake. It has had both for the last 165,000 miles (currently has 175,000 miles).

I installed ngk coils originally and they lasted the longest ( around 8k miles before the first one went ).

Aftermarkets (especially APR/MST) are reported to fail often, like *very* often.

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.
