The Edelbrock #3818 is a single-bore 90mm throttle body designed with a 5.0L Ford-style base pad. It is fully machined and assembled by Edelbrock. It includes a Throttle Position Sensor, a progressive throttle cable lever, and cruise and kick-down attachments, all on a threaded shaft for ease of customization. The IAC mounting flange will accept any Ford 5.0 style IAC including our pulse-width modulated Hitachi unit (# 36017). Since most people will re-use their existing controller, none is included. An IAC block-off plate is supplied if needed.#3818 comes with our #3520 Pro-Flo XT EFI Ford kit (Discontinued), and is recommended for all Ford EFI elbow applications. #38183 has all the same components except the casting is powder coated with a black mini texture finish prior to machining.
