i'm trying to figure out if the recent code hissy fit after i got an obx header and 380 injectors could be due to the plugs being too hot.

here's the stock 6 range with the carnation hai and 12 disk supertrapp, looking a nice tan color after about 1.5 years:



here's a denso .4mm ik20 with the same setup after about 1.5 years, also looks a nice tan to me:



here are 2 of the ngk .7mm iridium after about 8 months with the 12 disk trapp, 2 months with a 15% pulley and 18 disk trapp, and 2 weeks with an obx and 380s and the 18 disk trapp. the pictures don't convey how much whiter these are than all the others. does this look hot/lean??





thanks.

 

They look alright to me unless I am color blind. Hot means it's very whitish including the walls but the walls in your picture still have some carbon sooth left. The 380 injectors should run on rich side & cooler flame if it has not been tuned i.e ECU.
