vs
Spark plug Denso or Motorcraft
Reviews
i just put the densos in my '17 alltrack with a stage 1 tune and they run noticeably smoother than stock. i gapped them to 0.026" before install. it didn't seem like plugs would be that important for a stage 1 tune so i've been surprised.
Pros: runs noticeably smoother
Vehicle:
Volkswagen
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
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
NGK/Denso are good plugs for my car I used IK20 Denso plugs as they are iridium plugs which is what you want as they last much longer and are better quality
Pros: better quality, last longer
Vehicle:
Mazda
Part number: IK20
I've been running Denso Iridium on 7 Saabs for years.. both 9.3 V6 and 9.5 2.3l... never an issue on any after 100s of thousand of miles.
Pros: no issues, long lasting
Vehicle:
Saab
switched to the back to the motorcraft spark plugs $15 a piece fixed it for a while
Pros: fixed issue temporarily
Cons: issue returned
Vehicle:
Ford
Mileage: 370148 km
my truck uses denso and NGK dual electrode plugs and will run very poorly if u try to use anything else
Pros: dual electrode plugs
Cons: runs very poorly
Yes! I had a set of iridium spark plugs bought off Amazon that were counterfeit! They were denso but I didn’t discover it till about 40k miles later when I had a misfire. Pulled plugs and they were toast… first set lasted 120k and looked fine..
Cons: plugs were toast, misfire
Mileage: 64373 km
