im going to change my spark plugs to denso iridium , but im confused to choose which model of the spark plug is suitable to use in BLM.

i read many people were using IT20, but then the mechanics/foreman recommended using IK16 who mentioned IT20 is not suitable in BLM.

so kindly please advise which is the best for BLM. IT20 or IK16? thanks.

wrong post.

some inquiry here, is chamber nut/bolt required?

i was inform by the mechanic mentioned that my ride need to add chamber bolt which cost RM40, due to the right chamber was out of place (lari liao).

so please advise, does it necessary to add that? thanks.
