Description
Upgrade your GM LS engine with this downdraft individual throttle body kit from RHD Engineering, supplied by Devil Performance Parts. The progressive linkage is designed to provide controllable light-throttle operation while giving each cylinder its own throttle for performance-focused street and track builds.
Choose the cylinder-head port style first, then select LS1 cable operation or drive-by-wire and the available trumpet or scoop arrangement. Cathedral-port options include short or medium trumpets, with a backing-plate option on the medium version. Rectangle-port options also include tall trumpets and a carbon scoop.
Key Features
- Sixteen configurations covering the listed port, throttle and intake-layout combinations
- LS1-style cable, throttle-position sensor and idle-control fitment on cable versions
- Provision for higher-mounted secondary injection
- Factory-ECU tuning supported by RHD
Vehicle Fitment
| Make | Engine / Application | Fitment Notes |
|---|---|---|
| GM / Chevrolet | LS1-style cathedral-port cylinder heads | Choose Cathedral (LS1). Confirm the actual head ports and cable or drive-by-wire requirements. |
| GM / Chevrolet | LS3-style rectangle-port cylinder heads | Choose Rectangle (LS3). Confirm the actual head ports and clearance for the selected trumpet or scoop height. |
Note: Please check cylinder-head port shape rather than relying on the engine badge alone, particularly on modified or swapped engines. LS7-specific kits are not included among these configurations. ECU calibration and engine-bay clearance must suit the installation.
