Check your plugs, guys..(not 56k friendly pic)
Whoa! 
Left two are #1 and #2 Leading(7EQ), Right are trailing #1 and #2(9EQ). Cooked the edge right off after 4k miles on trailing #1!!
Replaced factory NGK 7 and 9's with platinums(still 7 and 9's), even though expensive. No more cold-start backfires and she screams like a banshee to fuel-cut now. Motor is still tight. (42kmi, '93, 10psi boost-controlled,stock ECU). Anyone get another read on these plugs please post.
Do yourself a favor: Go at the plugs with a 13/16 plug socket from the bottom. Borrow a race-jack and a single jack-stand if you need to.

Not to get into another "7's vs. 9's all-around" debate, but with just a DP, intake, CB, stock ECU, AWS intact, 10-11psi max psi controller-limited and stock intercooler they work fine as designed.
