Spark plug Autolite or Denso
Yes definitely get the original OEM Denso plugs and be really cautious of anything you purchase off Amazon a lot of them are counterfeits. You can either go direct to the Toyota dealer or you can go to your local parts store like Napa and just make sure you order the correct Denso Plug.
The plugs look really good pretty even color across all of them no major carbon buildup. Wear on the plug seems typical for 100,000 miles.
Pros: even color, no buildup
Cons: wear after 100k miles
Mileage: 160934 km
I've been running Denso IKH24 for 10k miles, have to swap them often but they've been great so far. Frequent changing will prevent damage to them seeing as they are normal projected grounds, but they are pretty cheap to replace once a year or so.
Pros: great so far, cheap
Cons: swap them often
I run [Denso 5749](https://www.densoproducts.com/denso-5749-ikh01-24-iridium-racing-plug) non projected tip plugs with my FBO IS38 car.
They're 1 step colder, and non projected so the risk of a strap breaking off [\(like this\)](https://i.imgur.com/gdJFaJ4.jpeg) are extremely rare.
Pros: strap breaking extremely rare
Denso or Bosh are the best you can return and get new ones
Pros: best quality
Use NGK and if you can’t find them then go Denso. The only 2 plug brands I would put in a Honda.
Pros: reliable plug brands
Vehicle:
Honda
Them Autolites are sweet, if they were edible I'd ask for them in my Kung Pow?
Pros: sweet performance
Vehicle:
Volkswagen
My 2010 came with denso, replaced them with ngk at 100k, then at 200k replaced them with denso…not sure if it made a difference
Vehicle:
Honda Fit
Mileage: 100000 km
Ive got the densos twin tips in a vxr at present. One thing i can tell you is they dont like heat!!! i recently had a small coolant leak and they would misfire. pretty low heat resitance i think. work fine on cooler engines.
Pros: work fine cooler engines
Cons: dont like heat, misfire
it was the Autolite spark plugs. Had car towed to my mechanic. They replaced with spec NGK and the car is running fine.
Pros: car is running fine
Cons: car misfires
Vehicle:
Mazda
I bought Autolite spark plugs but after researching I should of bought NGK. Right after replacing them when I accelerate my car jerks or misfires when driving. When at an idle I felt my car jerking.
Cons: car jerks or misfires
