Spark plug OEM Toyota or Denso

My car was fitted with Denso Power when new, 11 years ago. It has done 63K Miles (101K Km, way more than the data sheets above say) and the economy continues to improve

I was running APR coils and went back to OEM. That helped. So did going to the Denso 5750 plug and getting an EQT grounding kit.

The DENSO spark plugs are 6 for $23 at walmart. These get great fuel economy , smooth idle, Great Power.

Have some I'm waiting to try out in my turbo 4age after using bkr7e ngks for years. I mean denso is an A1 company and they offer heat ranges colder than NGK so probably worthwhile for my turbo engine.

I have an 02 4runner with 289,500 miles. I've had it for the last 106,000. Replaced the timing belt/ water pump twice. Replaced spark plugs twice. New brakes a few times.

2019 4 gen - dealer sparkplugs were part number ZC20HPR11 > Denso spark plug.

I’m from EU, Scandinavia and that part number were on my original ones I pulled out.

Plugs(Denso IK22) coils(DENSO or Hitachi) and a valve adjustment, all due at 100k. They really do make them run better and much more reliably.

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.

the tips of the IKH24s break off in expensive TTRS engines.

I have the 24's, not impressed.
