IMPORTANT: These throttle bodies will NOT work on vehicles with a throttle body that point upwards. If you have an upwards throttle body from the factory, the only way around this is to also purchase a Skunk2 intake manifold that fits your application (some extra work and parts may be needed to get everything working)
We include all necessary hardware for installation, including the vehicle specific wiring harness, with each application.
