Maybe it could be worthwhile starting a thread called "Regional Differences" or so...

Guys.. this is what I've got:
from Denso Europe
Attachment 12124
Differences:
- Electrode Gap
FK16HR11 = 1.1mm
IKH16TT = 1.0 mm
http://www.denso-am.eu/e-catalogue/
FKxxHR11 iridium electrode = 0.55mm
IKHxxTT iridium electrode = 0.4mm
Attachment 12125
In comparison, NGK's LZFR5BI-11 center electrode = 0.6mm

Looks like more confusion. This is what they say for the 1.0L:
Attachment 12129
This is what the European manual says for both models:
Attachment 12130
Don't forget Automatic Stop & Go.
Oh and the 1.0l, collision avoidance, go faster paint jobs, and sunroof.
The E3 plug # is E3.68 I think.
Not to add to the confusion of this discussion, but sites like RockAuto.com suggest a different Denso plug for a 2017 Mirage (DENSO 3433 {#SK20HPRL11} Iridium Long Life, Gap .044). AutoZone NAPA, and others also direct 2017 Mirage owners to Denso part #3433, which is different than a Denso IKH16TT.
Whereas RockAuto list 6 different types of Iridium plug options for a 2015 Mirage, & a number of NGK & Denso plugs are listed.
Pulling plugs you are happy with and replacing them with the same may be the best option.
Denso 3433 SK20HPR-L11 Iridium Long Life Plug has a bigger 0.7mm Iridium Tipped Center Electrode
Attachment 12144
IMHO we should be more concerned with the correct Heat range rather than with the so many choices of plugs having different center electrode sizes.
A few MPH members even used a colder NGK 1483 LFR6CGP platinum plug which is cheaper and reported better performance than the stock iridiums [at least in our country].
how much does this cost @Mitz NGK 1483 LFR6CGP
do you have a link where to buy here in PHLs??
