Isnt it the same for the 8 as the 9 ? i made a order of BPR8ES i hope it will work good?

 

well you better cancel that order man because the 8 and the 9 are not the same the 9 has to use a iridium plug

 

Ok, why does it have to use iridiums? I really dont wont to use them on e85

 

You don't have to use an iridium plug, but that's all that's available right now for an IX. The BPR8ES is too short. I'll try to find the specs.

You can see that the Evo 8 plug (BPR8es) has a 19mm reach and a 13/16" hex head size, while the Evo 9 plug (ILFR7H) has a 26.5mm reach and a 5/8" hex head size. I've used the ILFR7H and was very happy with them, and about a year ago started running the Denso IKH24 (1 step colder than stock) The Denso IKH22 is a direct cross with the stock NGK ILFR7H.
