Looking at the chart Jime provided, the part number for the NGK Iridium 2 Step Colder plugs should be, LFR7AIX-11. On clubplug.net and elsewhere, the part number is LFR7AIX without the "-11". I pm'ed Jime but I'm purchasing the plugs in the next few. My question is, is this the right part number...LFR7AIX?

Sorry if this has been brought up a couple of times, I just haven't been able to find the correct part number in any of the previous post.

Thanks

 

LFR7AIX is correct. The -11 is only the gap designation if there is one. It 1.1 mm or approx .044".

I'm a little slow today getting old.

 

I appreciate you clarifying that for me.......i'm getting old too, and staying confused.
