I've been looking everywhere (on the net, at autobacs etc) I can't find a part number or size etc for rb25det Denso Iridium plugs. Can any one help me out. Also what kind of experiences have you guys had with different plugs ? Preformance differences, better worse, gap size etc. Thanks in advance.

Eric.

In all the turbo Skylines I've owned I've stuck with NGK plugs. Either double platinums or Iridiums. As far as part numbers I wouldn't have that for the RB25DET, sorry.

Gapping has always been 0.9mm or .035 inch.

Either or but the Iridiums are cheaper priced and I've seen absolutely no difference in performance on a dyno. The double plats are nearly 2x the cost btw.

I found that a gap of 0.8mm works well on the 25t
