Choosing the Right Part
Match the part to your chassis code and your current engine bay layout rather than model year alone. Points to check before ordering:
- Chassis code: this collection is for the GD Impreza WRX and STI. Related Subaru platforms include GC8, GE / GH / GR / GV and VA, and some parts — such as the GIR catch can — are listed for WRX / STI (GD / GE / GH / GR / GV / VA), Forester (SG / SH) and Liberty (BL / BP).
- Intercooler configuration: the GIR intercooler splitter is listed for use with a GR STI top-mount intercooler, and the 52mm silicone throttle joiner is listed for top-mount intercooler setups across GD to VA.
- Size and diameter: confirm stated sizes, such as the 52mm throttle joiner, against the inlet or outlet diameter on your car.
- Existing modifications: aftermarket intercoolers, piping, turbo or intake changes can alter clearances and hose routing, so compare against what is actually fitted.
- Colour and kit contents: where options are offered, colour and kit contents are shown on the individual product listing.
The fitment notes on each product page are the authority — read them in full before adding to cart.
Installation & What You'll Need
Installation by a professional is recommended. Silicone hose kits, throttle joiners, intercooler splitters and catch cans all involve working around cooling, induction and crankcase ventilation systems, where incorrect fitment or clamping can cause leaks or engine damage.
- Work on a cool engine, and expect coolant loss when a radiator hose kit is replaced — have fresh coolant on hand for refilling and bleeding the system.
- Hose clamps sized to each joint, plus basic hand tools and sockets for bonnet-area access on the GD.
- Time to route hoses and check clearance to the bonnet, intercooler, turbo and any brackets before final tightening.
- Catch can installation requires suitable mounting and hose routing, along with a plan for periodic draining as part of ongoing maintenance.
- Re-check clamps, hose seating and for leaks after the first heat cycle.
