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.
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.
As an ASE honda mechanic stick to OEM Only which will be NGK lazer Iridum or Denzo Iridum plugs. Cheap plugs foul and cause wear and tear on ignition coils and other electronics. As well but not limited to possible system lean codes and fouled injector tips.
Pulled the plugs and the center electrode is rounded off pretty bad. Gap is more than twice as much as spec. After replacing the plugs with OE NGK the bike is back to purring like a kitten so it was the plugs for sure.
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…
I tried it once after reading about that. Used ngk plugs. One of them seized and snapped on me trying to remove it. Only plug I’ve ever had seize.
