vs
Spark plug OEM BMW or Denso
Denso work quite well
Pros: work quite well
The plugs EQT recommends are compatible. I’ve been running Denso 5749 plugs for over 10k without issue
Pros: compatible, no issues
Mileage: 10000 km
Part number: 5749
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
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
Careful with Denso, back in MK7 days some complained that the plugs would shatter and cause engine damage.
Cons: plugs would shatter
Vehicle:
Volkswagen Golf
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
