Reviews of Denso spark plug

Denso and Bosch have worked well for us on a 1.6.

Denso itv20 (5339) for stock/mostly stock. ITV22 (5340) step colder if more mods. I have only used itv22 since 2015.

I went with Denso's on my 1.8T because that is what I had on the shelf. but I have ran anything and everything in vehicles over the years, and found that there is not much different between the different types.

As always, go with NGK or Denso plugs.

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.

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

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.

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
