Air Bleeds
Note: Air bleeds are the little plastic diffusers that go in the hole under the injector. 84-88 non turbos use a one piece bleed, while 86-88 turbo and all 89-92 use a two piece bleed (Top & Bottom). These pieces almost always break when removed from the engine. Air bleeds are supplied with their O-rings installed.
