Spark plug BRISK or Denso
Get a Brisk spark plug. Worked for me
Pros: Worked for me
Denso always.
Pros: good quality
Vehicle:
Toyota
I also went with the IKBH20TTs. I noticed my mpg was better after doing so, and the truck seemed to idle and drive smoother.
Pros: better mpg, smoother idle
Mileage: 95000 km
Part number: IKBH20TT
I ended up going with the Denso IKBH20TT because I couldn’t find any FK20HBR8 at a reasonable price and availability.
Part number: IKBH20TT
Been using the cheaper Brisk brand and never had an issue for 20k miles.
Pros: no issues
Cons: cheaper brand
Mileage: 20000 km
The spark plug on the right is 10000% original because it's still working even though it's over 5 years old and has more than 87,000 km on it. The new ones show a little over 5 kilo-ohms, which matches Denso's specification. The old ones show a bit over 3.5 kilo-ohms due to wear.
Pros: still working after years
Cons: lettering looks different
Mileage: 87000 km
Brisk silver er10s if you need 2 steps colder. I had the ngk plugs, but they wore down just as fast and are more expensive. Brisk silver are like 10 bucks
Pros: cheaper than NGK
Cons: wore down fast
Part number: ER10S
Bought some Denso 3450 Irdium plugs online. After reading about counterfits. I decided to test mine.
All are gapped .43 for the OEM spec for a 2014 Nissan Xterra. I measured the Irdium electrode tip which is 0.7mm and appears blue
Pros: gapped to OEM spec
Cons: potential counterfeit risk
Vehicle:
Nissan
Part number: 3450
I tried one of the economy plugs on my 02 Accord. Ended up having to chuck it and buy a Denso.
Pros: learn from my mistake
Cons: waste of money
Vehicle:
Honda Accord
I tried Denso once. I took Denso’s out and replaced them with Denso’s. They ran for 500 miles and quit.
Cons: quit after 500 miles
Mileage: 500 km
