Description
The standard intercooler radiator on the supercharged V8 Jaguar XKR 4.0 Convertible is one of the system’s weak points – it’s small, restrictive, and struggles to control intake temperatures under load. Power loss from heat soak is common, especially on cars running upgraded pulleys.
This new Powerhouse intercooler radiator is a direct-fit replacement that increases both cooling efficiency and overall coolant capacity. Designed in the UK, it’s a high-quality solution for owners who want dependable cooling without modifying the car’s original setup.
Performance Benefits
- 50mm thick core for greater heat rejection
- 70mm billet end tanks that increase the coolant volume in the intercooler circuit
- Helps stabilise intake temperatures during sustained boost
- Reduces power loss from heat soak
- Essential when running upper or lower pulley upgrades, especially in warm climates
- When running dual pulleys this upgrade is necessary
Construction & Design
- Full CNC billet end tanks – stronger, cleaner, and more precise than welded sheet aluminium
- CNC-machined hose connections for exact alignment
- CNC-integrated bleed fitting, redesigned to prevent hose stretch or misfit
- 6 mm billet mounting brackets with CNC-cut precision for a perfect fit every time
- Polished aluminium finish for a professional appearance and corrosion resistance
- Retains the OEM snap-fit top hose connection – no custom pipework required
Each radiator is hand-finished and pressure-tested before dispatch to ensure consistent build quality.
