Hi Friends

I have a honda jazz 1.2 for 2003, and this motor L12A1 need 8 spark plugs.

The question is the normals worth 28€ for 8 and the iridium 65€ for 8 on ebay.

What you use on yours jazz/fit and it worth the investiment of iridium?

This motor are designed for iridium...?

Thank You in advance

 

On "most" dual plug heads, there is a leading and trailing plug, I've found the trailing plugs do almost nothing, they are there to help emissions, BUT most of them have a shroud around the nose of the plug in the head so they really are not in the combustion chamber, On the old Nissan "Nap-Z" version we would only change the trailing plugs about every third time we tuned up the trucks. YMMV

 

Iridium plugs require less juice to produce a spark. Denso Long Life Iridium plugs are just that. You get what you pay for.

 

Honda uses Denso long life from factory. See below for part number for Denso.
