I tried to match my plugs up with the ones shown on this website but am a little uncertain. Any input would be appreciated.



Two shots of each plug.

last pic the center electrode seems a bit short, but while you have them out run some like 120 grit sand paper between the side electrode and the center electrode to clean them off. and make sure your gap is set right.

Last one also looks a scooch lean. But other than that, look good.

These look like NGK iridium plugs. The tip on these type of plugs are made of iridium, which will last a long time. Now as you can see some of this plugs still have the iridium tip on them, but the last one in the picture is missing the tip. this plugs are pre gaped when you buy them, do not gap them when you buy them new, these plugs are fragile to gaping. If the iridium tip is missing, then just buy new ones. These plugs are a bit more expensive than the regular NGK R's but are well woth it if you dont plan to change them for 3 to 4 years. the ones in my si have been there for 4 years of hard driving and they are still in good condition. I hope this helps.
