hi guys whats the spark plug part number for ngk ix iridium for a 2005 cbr 600 rr thanks

 

get the ngk IMR9C-9HE, im pretty sure those are the iridium ix's. And the IMR9C-9HES are the laser iridiums for our bikes.

 

What's the laser iridrium plugs? I have a 929rr I'm doing my bros 600 plugs for him I payed 9 bucks a plug for my iridrium ix plugs are the 600 plugs same price? I don't want to get the 30 dollar plugs from densco lol

 

the IMR9C-9HES are their top of the line ones according to them and the iridium ix's are a step below, when i was looking for plugs for my f4i last summer i came across a statement from ngk that said that. Either ones you can get a set of 4 for like $40-50 on ebay. Id say you dont really need em but if you can get them for the same price then whatever, why not. I got all 4 of mine for $20 i was pumped, just look around if youve got the time, otherwise just spend the $40-50 whatever it is. And as far as differences go between them its just the electrode thats used in the plug.
