My feels like it’s running brand new with 100k plus miles ????
The plugs EQT recommends are compatible. I’ve been running Denso 5749 plugs for over 10k without issue
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.
Denso always.
I also went with the IKBH20TTs. I noticed my mpg was better after doing so, and the truck seemed to idle and drive smoother.
I ended up going with the Denso IKBH20TT because I couldn’t find any FK20HBR8 at a reasonable price and availability.
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.
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
my truck uses denso and NGK dual electrode plugs and will run very poorly if u try to use anything else
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..
