NGK Iridium MAX Spark Plugs Question!

[H1ONDA EK9]

Hi

I currently use 'NGK Iridium MAX spark plugs BKR7EIX-11PS' but unfortunately I cannot buy them in this country anymore, only from Japan for this particular stock No. of 1175.

I originally bought these plugs about 5 years ago from a company in this country but it doesn't exist anymore.

1) Is there any difference in the normal Iridium one's to the MAX one's??

2) I have only done approx. 15k miles in 5 years, plugs are cleaned annually but is there a time span with these?

Any help would be appreciated.

Thanks

NGK Copper BKR7E-11 quarter of the price will do the job just aswell. Cheap enought to change every service and have the saticfaction of new plugs every time.

Fancy plugs are just a money spinner or for cars that have difficult plug locations.
