Spark plug NGK or OEM Toyota

I’ve replaced them alone (i’m not a tech, i am not even a beginner).

NGK plugs, 60 euros bought online, some tools i already owned, and I struggled with the spark plug socket, found it at a tech friend, the thing is that is necessary to be thin and i needed to borrowed a torque wrench. Half an hour of work.

Spark plugs took me 2 hours max to do myself. And it’s because I’m OCD so I was cleaning and taking my time. And it cost me $60 for the 4 plugs OEM NGK compared to $30 each at the dealer. Very easy to do.

OEM Toyota plugs will probably last forever but it depends if your gas mileage is like 5 to 10 miles less that's the only way I would change the back plugs.

I just got whatever the NGK equivalent was of the Denso IK22. One step colder works great on my car considering it gets thrashed. Comes up to temp extremely fast which helps fuel economy.

I've always used NGK plugs on my Hondas. My 2nd generation Fit I installed NGK Laser Iridium.

I went with NGK. Been great so far (been about 2k miles).

I replaced my own plugs. I got NGKs as I really like their quality.

I run NGK Iridium in my truck, they were like $17 each. That’s just my personal preference, I’m a boat mechanic and we put NGK in everything never had many issues with them except for these newer outboards running a weird plug that seem to foul after a couple hundred hours. I replace the plugs in my truck at like 250,000 miles. I currently have 370,000 on the truck and haven’t changed the plugs yet.

Year ago I bought 2018 R3 for track, for maintanence purposes ive changed spark plugs then, for CR8E obviously because everywhere in Internet and service manuals it says so. Also i took out of this engine used CR8E so everything was fine. Now, funny thing is Im now in process of rebuilding this engine and after taking off engine head realised that spark plug is too short and i was like wtf?!… So for everyone who has at least 2018 R3, go for LMAR8A-9, too short spark plug will

work obviously, I did 3000kms this year on track, but this may affect performance…

Get those plugs out! I bought counterfeit NGK plugs from Amazon. By the time you get a misfire the ceramic may have cracked off around electrodes and damage your engine.
