I recently took my factory sparkies out at 59k, and whilst they did look sooty and black (typical of this car I believe) they weren't as gunky as those appear to be. you have a cobb ap don't you?,
take a log and show some folks here, likey running rich even the cobb ots maps run rich I believe. May need a good tune i'm currently in progress with rayd (Have been been running corksport stage 2 sri/tip/ic map) and he has had to modify the mapping table quite significantly to bring things where they should be.
