DO88 Big Pack Cooler Kit Porsche 991.1 2013-2015 Turbo/Turbo SThe 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 youre driving on the street, track, or under tuning. Key Features Motorsport

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:

• Porsche 911 (991.1) Turbo / Turbo S — model years 2013 to 2015.

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.
