Genuine Denso
Great spark plug, I checked these carefully on receipt to make sure they where genuine (as there are a lot of fakes about).

After using Denso's iridium tt plugs in my truck and van and getting great results. I found a TT plug with the proper reach, thread and heat range for my GeneRac GP5500, Denso (4709) IW20TT Iridium TT. Really easy starting, very stable with varing loads. You will know you are using a TT plug the first instant the engine starts because it sounds slightly different.

All Denson TT plugs are the absolute hands down best...... you will notice a big difference. It gets better and better. It will start burning cleaner...... I now put them in everything.
