vs
Spark plug Denso or OEM Volkswagen
Reviews
NGK OEM equivalents or Denso IK22 for a slight bump in performance.
Pros: slight bump in performance
Vehicle:
Honda Fit
I’m running Denso plugs in my car…no issues to report.
Pros: no issues
If you’re buying a used VW. This is the easiest one (Polo) to maintain.
1. Figure their parts change and maintenance schedules and follow. Check oil cap for oil type to use (15-20k is fine).
2. Always check oil hoses, rubber seals and gaskets (40-70k).
3. Change engine bushings (100k), chassis bushings (50k), transmission bushings (100k) for first time used buyer.
4. Check condition of all parts above before change, also include spark plugs. Stick to German OEM plugs (50k).
Vehicle:
Volkswagen Polo
I’ll stick with NGK and Denso.
Pros: reliable brands
I bought the absolute cheapest plugs available ($1.50/plug), and they are branded "Denso Toyota Iridium" - I assume fakes, but my magnifying glass does seem to show an iridium tip, and they work great.
Pros: work great
I did Denso 3297 from RockAuto. They work great.
Pros: they work great
Part number: 3297
I've always used the Denso SK20R11 plugs in mine and been pleased.
Pros: been pleased
Part number: SK20R11
I ran Denso iridiums for 100,000 miles on mine, they looked usable when I pulled them. Replaced them with NGK's, no difference in power generated.

Cons: no power difference
Mileage: 160934 km
