DO88 Big Pack Cooler Kit Porsche 991.1 2013-2015 Turbo/Turbo S
Product Description
The do88 Big Pack Cooler Kit is a complete, high-end charge-air cooling upgrade designed specifically for the Porsche 911 (991.1) Turbo and Turbo S from 2013 to 2015. It replaces the standard intercoolers, Y-pipe and inlet paths with a fully optimised system — delivering substantially improved airflow, lower intake air temperatures and more responsive engine breathing, whether you’re driving on the street, track, or under tuning.
Key Features
-
Motorsport-grade, high-density intercooler cores: UK-made bar-and-plate cores engineered for significantly better heat dissipation compared to OEM.
-
3D-designed cast end tanks: Precisely engineered end tanks for optimal airflow distribution across the core — reducing pressure drop while enhancing cooling efficiency.
-
Custom carbon-fibre ambient air guides: Air guides designed via 3D scans to fit the 991 bodywork and force ambient air through the core, rather than around it — maximising cooling potential.
-
High-flow silicone inlet hoses: 70 mm (2¾") diameter silicone hoses with smooth internal transitions, reinforced with stainless-steel wire and rated for continuous temperatures up to ~240 °C (464 °F). Designed to cope with high boost and thermal loads.
-
Optimised Y-pipe and full system flow: Mandrel-bent aluminium Y-pipe (63 mm/2.5") with smooth flow cast collector and optional methanol injection ports (blanked). Combined with the intercoolers and hoses, this kit delivers far greater flow capacity vs stock.
-
Complete installation package: The kit includes intercoolers, carbon air-guides, silicone hoses, Y-pipe, necessary seals, clamps, and all hardware — everything needed for a full charge-air system upgrade.
Compatibility
Fits the following vehicles:
Ideal For
-
Owners running software tunes or stage upgrades where factory intercoolers become a limiting factor.
-
Drivers in hot climates or track/spirited driving conditions, where intake air temps and charge-air heat soak compromise performance.
-
Anyone seeking reliable, high-flow charge air architecture, with reduced boost pressure drop and improved throttle response.
Why Choose do88
do88 has chosen not to compromise — the intercoolers use high-density motorsport-grade cores, cast end tanks, and carefully engineered flow paths. The carbon ambient-air guides ensure maximum utilisation of available cooling air, while all silicone and aluminium parts are optimised for durability and performance under high temperature and boost. The result is a system that beats OEM-flow and thermal efficiency substantially, and delivers measurable benefits in intake-air temperature reduction, airflow capacity and engine responsiveness.
