I put NGK B5HS plugs in mine, no complaints so far.
Torch F7tc took 3-5 attempts to crank. This NGK paired w my Wgen11500 cranks first try every time. Very pleased.
RX7 mark 1. Wouldn't rev past 6000 with Champions, replaced with NGK and sang like an angel. It's not the price, it's the quality.
Go NGK and Iridium. They are a better spark and help burn any sediment off the tip. Also bonus is, they last about 50-80,000km.
If you do get plugs, go with NGK plugs instead. Good quality.
I installed these NGK 94833 plugs a few weeks prior. They are pre-gapped to .031 according to Urotuning.
Guys I replaced the spark plugs tonight with NGK iridium plugs and my light went away. Thankfully it wasn’t anything more that
Out with the old and in with the ngk 94833
Don't use AutoZone crap
I replaced the spark plugs with NGK Iridium IX factory gapped to .044". Everything went smoothly, reinstalled coils, air box, battery, connected MAF, and started the car. Now it is shaking, smoke coming out the exhaust, and blinking check engine light.
2018 Kia Soul Base, 57k miles, on the third set of plugs and they are misfiring already. Factory plugs lasted 30k miles, followed up with Autolite plugs lasting 10k (which I chalked up to being cheap/low-quality plugs), but now these NGK iridiums are giving out with 17k miles on them.
