Spark plug Denso or OEM Volkswagen

I just changed my plugs at 75,000 miles...I was impressed as to how clean the plugs were and the color. Looks good. The gap was still .030 as the new ones were (VW 06K905601K). Definitely could have gone much longer but it's an easy replacement.

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.

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

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.

Denso or ngk. Bosch at worst. I would recommend against the off brand in your photo.

Careful with Denso, back in MK7 days some complained that the plugs would shatter and cause engine damage.

my truck uses denso and NGK dual electrode plugs and will run very poorly if u try to use anything else
