LX5 65mm Throttle Body Adapter

We have designed an adapter to use the 65mm TB found on the Oldsmobile 3.5 DOHC. Bolting it to the manifold (3100, 3400 or 3500, both bolt patterns and sets of bolts are included) is no problem, but attaching the throttle cable bracket will be a DIY project.  You will need both gaskets for the 3400 (FelPro 61304 for the TB to Adapter and FelPro 60983).  The 3500 upper will need silicone to seal the adapter to the manifold instead of a gasket.  We modify the 3400 gasket for the 65mm bore if you buy it with the adapter.

You can find this throttlebody on the 1999-2002 Oldsmobile Intrigue and 2001-2002 Oldsmobile Aurora.
