Believe it or not my local Acura dealer is where I ended up getting a lot of the parts I needed for my current build. Myacuraparts.com They were even cheaper then Honda on a lot of the parts, but not all. Some were a few dollars more. If you setup an account and hold off on purchasing your parts, you can get multiple offers for cheaper shipping costs. I use Honda website to get the parts number and search to see if Acura has them. In notes during purchase enter the vin number and vehicle details. Lots of parts from Honda and Acura are backordered, so you might want to call/email ahead of time to make sure you can even get the part. This applies to any site you purchase from. For whatever reason they don't update their systems to reflect this, until after you purchase and they tell you. I think they put a hold on your card, but won't charge until they send. Expect some sites to not charge you for some time, and make sure to keep those funds available for this.
