The 8 is the right iridium.

Very cool! Thanks for all your trial and error research so the rest of us can benefit.

Using SparkPlugs.com cross reference and the Spark Plug Part-Number Interchange Guide that Phil posted, here are the equivalants I came up with using the NGK DPR8EA-9 :

Denso Iridium Racing IXU01-24 ($35.00)
Denso Iridium plug IX24B ($11.99)
NGK IX iridium DPR8EIX-9 ($6.95)
Splitfire Triple Platinum TP416C (No longer available)
Splitfire SF416C ($3.99)
NGK DPR8EA-9 ($2.24)
Autolite 4163 ($2.24)
Champion RA6HC ($2.24)
Denso X24EPR-U9 ($2.24)

I couldnt seem to track down much on the Bosch plugs except that spread sheet shows XR4CS as the regular Bosch spark plug number. I was hoping I could find an equivalent for the Bosch Platinum+4.
