Spark Plugs?

[SX2002]

What spark plugs are in a stock S15? Make and type? Are they NGK Platinums?

well Im ordering ngk iridiums. bkr7eix. im trying to figure out what the difference is between those and the ones that end in 11 besides the gap. for some reason people always refer to the bkr7eix-11 for the sr, but they are gapped at .44 , the bkr7eix are gapped at a perfect .28, so I dont know why people still refer to the bkr7eix-11, its probably a non issue but gapping from .44 to .28 from some other members on different forums -- will weaken the ground and it is prone to breaking off. As far as I know these plugs should be good for your car too. mines an s13 redtop.

Def. NGK iridium plugs for the money.
