O-ring part number request

Recommended Posts

Hi guys,

I checked but can't find the part number of this o-ring in the photo. It's the hose connection from the AOS to the throttle body.

Any ideas? Mine is a 2003 C2 coupe. Stick shift.

Also, the catalogue says the throttle body gasket on its right in the photo is G99611031750 but it's the wrong part! I bought it but it's bigger and thicker. The right part looks like it's this one http://www.autoatlanta.com/results.php?partnumber2=99711031900 , which is however listed only for Carrera 4. Any ideas?

18 x 2.5 mm?

If so, then it is 999-707-446-40 about $2.25 each MSRP

Thanks, Loren. The part you gave is #22 in this diagram. However, what I'm looking for is the o-ring on the left end of #5 (which connects to the throttle body). Do you know if such o-ring is avilable individually or I have to buy the whole #5. I suppose I could replace the o-ring, measure its size and get an equivalant...Thanks.
