The throttle bodies get bored out so the engine can breathe better; improved air flow.
RENIX version can be only bored up to 60mm. Anything larger than that would open up a hole on the side! Stock butterfly diameter is 52mm. Newer 60mm butterfly is installed in its place.
1991 and up to 2006 throttle bodies are 60mm at the top with a 60mm butterfly plate but tapers down to 56mm at the bottom with a bottleneck. Theres two available options for this version… I can either bore the bottleneck out to 60mm to match the entire bore, while retaining the original 60mm butterfly plate. OR I can also bore it out to 62mm all through with a brand new 62mm butterfly plate.
The 2.5L throttle bodies are 48mm and get bored out to either 60mm to match the 4.0L bore or to 62mm.
Each and every throttle body are glass beaded to a satin finish for a better appearance.
