Spark plug NGK or OEM Toyota

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

Sparkplugs replaced at 85,000km, with NGK Iridium plugs.

I buy parts from them for my Volvo. Even with the cost of freight , it's miles cheaper.

I've recommended many times to toss plugs and replace with NGK (you can read about my experience in prior post). You have hopefully educated newbs to follow you.

We bought a 2015 Mazda CX-5 that has 155K miles on it. Plugs never changed by prior owner. It was giving us **26 MPG**. The engine was rough at idle. So I read and read about Spark Plugs and purchased NGK LKAR7AHX-S Spark Plug NGK Ruthenium HX Spark Plug that this is better then the OEM ILKAR7L11. So we installed the HX, we noticed the engine smoother but the MPG dropped down to **24 MPG consistently.

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.
