HRC Head Conversion Spark Plug

Hi guys...

i was looking what spark plug i have to use in order to have enough clearance between the spark plug cap and the front wheel and i found the NGK R7282... The good thing about this type is that is produced in many heat grades 7-8-9-10-10.5 and 11...

The question...: Is this type R7282 suitable for my MC28...?

This type of spark plug uses the NGK TRS1225 cap... But i can't find it in Greece... Do you guys have access to this type of cap...? Is there any internet shop that sells this type of cap...?

Thanks
Michael

Suitable but very expensive...
Try the NGK R5300A range of plugs. Also a shorty type plug, as good as the 7282's, but cheaper. I think the 7282's are set up for det counters, (don't quote me on that)...
I have used R5300A-105's.

Thanks Kieran,

But what type of cap must be used along with the R6252E-105 spark plug...? Is this also a short type of spark plug...?

About the cap...? Does the TRS1225 suit to the R5300 plugs...? Or i have to use another cap...?
