This is really a 2013 Honda Civic Si question however it applies to 2013 Acura TL.
Has anyone used these plugs, my neighbor ask me " The gap on the Denso Power plugs are like 0.35 and the Long Life ones are 0.44, do I leave at the factory gap?" I guessed to leave it as is
The iridium plug has a smaller fine iridium point 0.4 and difference between stock is 0.2 to 0.3 so like 0.08 and 0.11 inch difference, is that reason the gap is at 0.35?

So after rambling, Denso Power Iridium 5356 has a smaller gap 0.9mm(0.35 inch), leave it as is?
(looking for people who actually used these plugs)
Thank you.

I only use NGK Iridium plugs on my Hondas

Funny on my old rotor engine, the NGKs were junk and Denso were quality ones. Ya I heard the NGK for Hondas and Denso for Toyota. However that wasnt the question! Dang spamming Moderators (jk)
