Spark plug Denso or OEM Volkswagen

NGK OEM equivalents or Denso IK22 for a slight bump in performance.

I’m running Denso plugs in my car…no issues to report.

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).

I’ll stick with NGK and Denso.

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.

I did Denso 3297 from RockAuto. They work great.

I've always used the Denso SK20R11 plugs in mine and been pleased.

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.

Im running denso step 2 cold plugs from bms website and tbh i regret not going with the hks plugs

I got some phony Denso marked spark plugs
