HYBRID RACING K-Series Throttle Body

The Hybrid Racing 70mm K-series throttle bodies are by far the most feature packed throttle bodies on the market. From the design phase this throttle body was created with reliability as the priority while allowing as much flexibility in your setup as possible.

One simple, but very notable feature of this throttle body is the dual bolt pattern. By incorporating two bolt patterns, this throttle body is able to bolt directly to a PRB or RBC intake manifold. By eliminating the need for an adapter when upgrading from a PRB to RBC intake manifold, this throttle body can save you as much as $75.

Last, but not least, the three bolts used to fasten the brass butterfly to the stainless steel center shaft are staked. Staking is the process of deforming a bolt to prevent it from coming loose and falling out. This means that even if one of these bolts were to become loose, it would be unable to come completely out. If you’ve heard of people blowing up motors from bolts falling out of other manufacturer’s throttle bodies, then you know how important a feature this is.

It should be noted that a big bore throttle body should never be used on an intake manifold that has not had the inlet bored out to match the bore of the throttle body. A setup using a big bore throttle body mated to an OEM sized inlet port will yield lower performance than the OEM throttle body. That said, when boring the inlet on an intake manifold, it’s best to overbore slightly (about .25-.5mm is sufficient), to prevent the chance of a lip that could create turbulence.
