JQmod offers a full range of performance upgrade components for the Porsche 992 platform. This comprehensive Bigpack bundle includes upgraded intercooler cores, optimized charge pipes, and durable silicone hoses, forming a full cooling system upgrade that delivers long-lasting improved airflow and consistent thermal performance for modified 992 Turbo and Turbo S models.
This intercooler Bigpack represents the pinnacle of platform-specific cooling system tuning. Every component and flow path has been fully redeveloped with zero compromises to extract maximum performance across the entire charge cooling system. The upgrade utilizes premium motorsport-grade cores from renowned Garrett Motorsport, featuring precision thin stacked fins engineered to JQmod exclusive specifications, perfectly balancing high-efficiency heat dissipation and unrestricted airflow. Lightweight thin cast aluminum end tanks reduce overall weight while maintaining optimal air distribution efficiency. To accommodate the thicker high-performance core and unlock full cooling potential, restrictive factory air guides are replaced with premium high-quality carbon fiber ducts. All system connection points are enlarged to eliminate airflow bottlenecks, paired with JQmod silicone hoses featuring smooth, sweeping bends for streamlined charge air delivery. No sacrifices were made during the entire R&D process, delivering a truly comprehensive performance cooling solution.

Background
Previous-generation Porsche 911 models adopt a dual rear-fender intercooler layout, utilizing a Y-pipe to merge dual cooling cores before charge air enters the intake manifold. The 992 Turbo platform features a fully revised cooling structure, integrating the intercooler and unified Y-pipe into a single compact assembly mounted beneath the rear wing. Ambient cooling air flows through dedicated rear window channels into the decklid air scoop, passing directly through the intercooler core to achieve efficient heat transfer. While this factory layout delivers rational aerodynamic and thermal performance, it raises higher design standards for performance cooling upgrades. To fit larger-volume, larger-surface-area high-performance cores, we developed brand-new custom carbon ducts compatible with the increased core thickness. This project elevates our carbon fiber manufacturing and precision fitting capabilities, delivering a premium finish and OEM-perfect fitment worthy of the iconic 911 sports car.
Garrett Motorsport Performance Cores
This upgrade is equipped with top-tier Bar&Plate cooling cores professionally manufactured by Garrett Motorsport, representing industry-leading motorsport cooling technology. Dense precision-stacked thin cooling fins form a high-efficiency heat exchange structure with exceptional thermal dissipation capabilities. The 105mm (4-inch) thick cores are engineered to the maximum feasible thickness for the 992 Turbo platform, fully utilizing all available installation space.
Precision 3D freeform cast end tanks evenly distribute charge air across the entire core surface to eliminate uneven airflow and dead zones. The development of these end tanks involved extensive 3D scanning, CFD flow simulation analysis and iterative 3D prototyping to perfect the final functional design. We consistently prioritize cast aluminum end tanks over conventional CNC-machined alternatives, as complex cast geometry delivers superior airflow performance that rigid machining cannot replicate. For JQmod, functional performance always prevails over superficial aesthetics, with maximum airflow efficiency as the core design priority.
The end tanks feature precision-machined 70mm (2.75-inch) connection ports to support high-power tuning output. Matching premium JQmod silicone hoses are included to pair with these enlarged ports. Dual cooling cores connect to a unified central outlet tank leading to the intake manifold, integrated with precision machined fittings and dedicated methanol injection bungs for flexible upgrade compatibility.
Premium Carbon Fiber Ambient Air Guides
All air guide ducts are crafted from high-quality vacuum-infused prepreg carbon fiber, retaining complete factory air channel fastening grooves and mounting structures to match OEM specifications perfectly. Despite complex molded geometry, every carbon duct delivers flawless vehicle fitment with zero modification required. Precision rubber sealing gaskets are installed at all contact positions to eliminate cooling air leakage, ensuring all ambient airflow passes fully through the intercooler core to maximize heat transfer efficiency.
Upgraded Aluminum Charge Pipes
This Bigpack includes full JQmod performance charge pipes, a critical upgrade that replaces restrictive factory OEM hoses. The system adopts mandrel-bent 63mm (2.5-inch) seamless aluminum pipes with a premium satin black powder-coated finish, delivering long-term structural durability and drastically improved airflow consistency. The complete pipe set includes four matched silicone hoses, with turbo outlet hoses constructed from high-temperature resistant material rated for continuous operation up to 240°C (464°F). Constant-tension hose clamps are installed at key connection positions to automatically compensate for thermal expansion and contraction, maintaining a permanent leak-free seal under extreme high-load operating conditions.
Performance Testing & Verification
The JQmod upgraded intercooler system delivers significant, verifiable intake temperature reduction for 992 Turbo/Turbo S models. Full performance comparison data versus stock 992 OEM intercoolers is displayed in the product test charts. All real-world test data was professionally recorded using an AIM race logging system.
Testing was performed on a 757HP Porsche 911 Turbo S equipped with updated software and exhaust upgrades, completing four consecutive full-load test runs on a closed airstrip with zero cool-down intervals to simulate extreme track conditions. Each run consisted of continuous full-throttle acceleration from 50–250 km/h (30–155 mph), paired with hard braking between cycles. The vehicle’s active rear wing remained in the raised performance position throughout the entire test process.
The standardized test procedure began with four baseline full-load runs using factory OEM intercoolers. The cooling system was then rapidly upgraded to the complete JQmod intercooler kit. After a short vehicle shakedown period, five identical full-load test runs were repeated under completely matched environmental and vehicle conditions. The upgraded system achieves a peak intake temperature reduction of 12°C (21.6°F), delivering remarkable thermal stability under continuous high-load operation.
Balanced cooling efficiency and unrestricted airflow are the core of high-performance cooling system design. After extensive R&D refinement of end tank geometry and core specification selection, our intercooler achieves dual improvements in both heat transfer efficiency and airflow performance. All airflow data for JQmod upgraded intercoolers and stock OEM units is verified and calibrated on our in-house Superflow SF-1020 Probench flow bench, ensuring 100% authentic, real-world measurable performance gains.
