My suggested websites for some Honda DIY tech, info, and discussion:
Suggested websites to buy OEM Honda/Acura Parts:
eBay (yes you can find some good deals on OEM parts on ebay, both new & used)
Search Forum Classifieds for used parts, you'll find the best deals there.
Note: This list will continue to grow as I add to it. These are just some of the sites that I frequent.
