So I'm replacing the throttle body this week, already found one on ebay motors. I haven't taken it apart that far back yet but I'm thinking there's going to be a pretty crucial gasket on there. I've been trying to find one online but all that comes up are ads for TB spacers. This is the best I've done so far but the name they gave it throws me off a little http://www.dealerdirectparts.com/Pro...4296390-RX-8-4

Any help finding out where I can buy one would be appreciated.

Thanks!

Also, its a 2004 GT

 

there's an orange gasket in the plastic part that the throttle body bolts on to. It's kind of embedded in there so I don't see why you would want/need to replace it. Just curious, why are you replacing your tb?

 

Yeah, that's what I found when I finally got it off, didn't realize that it was just an O-ring.

The motor/actuator in my old TB was burnt out or just unresponsive for some reason. I found a 'new' one on ebaymotors for only $80, polished it up and the car runs great again.
