For the stock 75MM LS throttle body, we CNC cut the entry to allow a smoother transition into the throttle bore, which results in a crisper throttle response and an additional 5-8rwhp at wide open throttle. The shaft is also milled to a slimmer profile to maximize the overall flow capacity. This is a great upgrade while still retaining a completely stock look.
