NGK Iridium Spark Plugs

[DRO916]

Which one is the Iridium that is suggested to put into KA24DE? I went to the store and found these two:

NGK Iridium (IFR4E-11) and NGK Iridium IX (BKR5EIX-11)

Just trying to find out which one I should get

why do you want iridium? its like $13 each or some outrageous price. just go copper. i have and so have many other people. just a suggestion.

the one you should use are the 2271, i dont know the NGK code, but thats the stocking #.

Are you turbo or NA? BKR5EIX-11 is the correct one for stock heat range. If you are going turbo I would not use iridium. NA maybe but doesnt really seem worth it.
