Stepless eye clamp, 48.5 mm Oetiker

Where used:

2WD Urals: the larger of the two clamps for the rubber sleeve on the sidecar driveshaft. (Doesn't apply if you've got the later/upgraded CV-style driveshaft.)

2014-2018 air filter: Clamps the throttle body into the compliance flange (which is bolted to the cylinder head)

2019+ air filter: Clamps both ends of the rubber compliance flange that you see between the throttle body and the small intake manifold. (The manifold is the aluminum part bolted to the cylinder head.)
