Professional Products - Throttle Bodies (Save 20%)

Professional Products throttle dody are beautifully crafted from permanent mold castings of 356 aluminum. Permanent molds produce higher quality castings than conventional sand molds with reduced porosity and a better finish. One of the more critical areas of a throttle body is the fit of the butterfly in the main bore. Their butterflies are all hand fitted for the ultimate in accuracy and won't stick like other brands.

These throttle bodies are made as aluminum die castings and as such, appear very similar on the outside to a stock throttle body. However, the main inlet on all of these throttle bodies features a 3" O.D. which allows the use of many of the popular air inlet kits. We have both 65mm and 70mm throttle bodies for these engines. Each size is available in either a show polished or satin finish.
