Product Notes
Some port matching may be required when used in conjunction with CNC or hand ported cylinder heads.
The intake manifold is available with a standard or optional reverse throttle body orientation, allowing for more direct intercooler pipe routing.
Larger throttle bodies can be used with proper modifications (Up to 70mm with minor porting) (Larger throttle bodies may also require adapter flanges)
The intake manifold is flanged for 04+ STI drive by wire throttle bodies, but cable throttle bodies can be used with custom fitting and flange adapter.
Standard configuration intercooler piping will need mild custom fabrication due to placement of throttle body.
Reversed configuration requires the relocation of the alternator and removal of the A/C compressor.
Installation is not a direct bolt on and will require custom intercooler piping.
The intake manifold is designed to use a common Subaru aftermarket top feed injector size. (48mm overall length / 11mm inlet – standard Subaru rail size / 14mm outlet) We recommend the use of Injector Dynamics brand injectors.
Standard Subaru style injectors cannot be used. (Side Feeds, Stock STI Style Injectors)
Not compatible with stock fuel rails or lines.
Not compatible with top mount intercoolers.
Not compatible with hard pipe stock location turbo inlets, requires silicone inlets.
Not directly compatible with mounting the factory upper coolant reservoir.
