Can I use IK22 Denso Irdiums???

The denso site says IK22G, but I know IK22 were ok in the past.

What is the G????
Need help ASAP

Thanks

 

I just put in a set of IK22 denso irridiums in my 02 S2000 and they work just fine

 

I use it few month, but at idle my car does not work right.
(It shut off sometimes)
I change plugs back to original and everything goes fine .

At the moment I use ngk #7173 (plugs what many people here recomened )

 

that weird, i've got about 500 miles on my IK22 denso's and havent had any trouble at all, my S runs great on them

 

I've heard mixed stories about aftermarket plugs. I've also seen too many times when someone tried to "upgrade" and ended up going back to stock. The OEM plugs are fine and have a different washer to keep them from backing off at high vibration. Unless you're running a forced induction setup, I wouldn't worry about changing plugs out.

 

I agree. First few hundreds km was almost ok, then that plugs start to play with me. Hope so you gonna be ok !
