I'am using Denso iridium IK20's as of now(wich is what denso's website suggests for use with the s13 SR20DET), i'am thinking of going with the denso copper plugs though. Wich NGK's are you using ? Where did you get them from ? I went all over and couldn't find a store that stocked any NGK's for SR's.
