Replaced the coil packs in my new-to-me car in hopes they were the source of my poor fuel mileage, turns out my heavy foot is mostly to blame. 6 coil packs, same revision as the latest version I installed from the dealer (coil packs were likely already done under recall). Not sure how many miles are on them but they were not misfiring or generating any codes. I'll get specific part #s and pics when i get home. $70 shipped.
