You can run NGK Rutheniums, i run them on with my is20 and no complaints either.
Owner reviews for spark plug
I swapped for Rutheniums, No complaints and its a easy job
Stick to NGK R7437s. They are pricey but the best plug for a tuned car forsure. I inspect the gap every 5k miles and replace every 10k. Mine are gapped to .022
I’d go with the recommended NGKs, buy from fcp euro and you only need to pay for them once. Those are what I run on APR stage 2.
I'm running brisk One step colder plugs at 0.024 Gap with my eqt stg 2 tune. they are amazing
Acdelco plugs....Never had problems with either
I used them in my 2007 Tacoma with no problems. Left them in for several years.
would suggest plugs, RS7 or Brisk 12's (cheaper) but coil packs are not needed.
Bought these exact plugs recently and had the same problem- tip doesn’t unscrew- had to return them.
Im running denso step 2 cold plugs from bms website and tbh i regret not going with the hks plugs
