Always stick with NGK. However, NGK has different lines from copper, to platinum, and iridium. Iridium is more expensive, but will last longer. Given they're a bit of a PITA to replace, I'd go with these. I've run them in my 2004 WRX the last 8 years.
if the car isn’t stock and has been tuned, you’ll want to follow the recommendations of your tuner/just put NGKs in it.
I got mine from ECS: drop-in replacement and no issues even with my Burger unit on map 2.
Car is very picky about spark plugs because it uses the spark plugs as knock sensors, I used basic NGK copper plugs and replaced every 10k. Very easy to do.
I currently run the Brisk er12s and have been happy with them...I'm mpi running full e85 and the car responds well. It's also what my tuner recommended.
Just changed my spark plugs.. went from 031/032 factory NGK1675 gap down to 027/028 gap (based on the feeler leaf gauge). i am here to state beyond shadow of a doubt that 027/028 gap feels way better. The car is smooth.. so smooth in fact that it makes me feel like the CEL is about to come on. In 7 years of ownership, I never felt it as smooth as it feels now. When idling I almost feel as its off.. also at speed!
I got a set of APR coils and Brisk Silver Racing ER12s plugs for around 200
Got new NGK BKR8EIX pugs today and gapped them to 0.024". Originally, 0.030" according to my gauge. Very surprised when I removed the old plugs as they were all at varying degrees of tightness even though they were originally torqued to 25NM. Car runs great with the new plugs. No complaints so far.
I have used Rs7 plugs (meh), the APR recommended NGK plugs (rough idle, gapped correctly), and the Brisk ER12S. I'm on my second set of the Brisk, and plan to keep using them.
I have replaced many brand new NGK's in newer chryslers after the customer gets them from a parts store. NGK's can and will cause ignition coil secondary circuit codes. Also, on hemi's they will set asd control circuit codes and cause the car to stall.
