Pipercross Airmax G8X M2/M3/M4 Carbon Intake Kit

Pipercross G8X M3/M4 AirMax Intake System | Avon Tuning Store

Unleash your BMW G8X M3 or M4's full performance potential with the Pipercross AirMax Performance Induction System, available now at Avon Tuning Store. Crafted with precision carbon fibre and advanced engineering, the AirMax system is designed to deliver unparalleled airflow, power, efficiency, and stunning induction sound — tailored specifically for your S58-powered machine.

Key Features:

• Carbon Fibre AirMax Lids: Over 24% increase in outlet size, optimised for maximum post-filter airflow.

• Carbon Fibre Intake Cross Pipe: Volume and flow-optimised for the S58 engine bay cavity with aluminium-reinforced inlet/outlet connections.

• Pipercross Plus Filters: Featuring multi-density hybrid foam and CNC-laser cut stainless steel backing frames, delivering a 22.1% airflow gain over standard mesh frames.

• Performance Silicone Hoses: Step-matched, thick-walled 5-ply silicone hoses for perfect fitment, maximised airflow, and OE-level flexibility.

• Proven Airflow Gains: Up to 84.26% maximum and 62.59% average reduction in airflow restriction vs. the full OEM intake system.

• Dyno-Tested Power Gains: Increase up to +11 to +30 HP and +16 to +35 Nm torque from stock to Stage 1 tuning levels.

OEM Intake System Assessment:

While BMW's OEM G8X intake design meets factory power targets, it quickly becomes restrictive under tuning conditions. Pipercross engineers identified the filtration media, airbox outlet sizes, and intake pipe volume as key bottlenecks, leading to a complete redesign using lightweight, high-strength carbon fibre.

Plus Panel Filters – The Heart of the System:

The Pipercross Plus Filters provide the foundation of the AirMax system, significantly outperforming the stock filters. With hybrid foam construction and industry-first stainless-steel backing, they deliver maximum flow while maintaining superior filtration efficiency — reducing airflow restriction by up to 47.47% compared to OEM filters.

Redesigned Carbon Fibre Airbox Lids:

The AirMax carbon fibre lids maximise the potential of the Plus filters, offering increased post-filter volume, enlarged 98mm outlets (+24% and +75% over OEM outlets), and flow-optimised geometry for superior laminar airflow. Aluminium outlet rings ensure long-term durability under extreme heat and stress.

Carbon Fibre Intake Cross Pipe:

The carbon fibre intake cross pipe was meticulously engineered to maximise internal volume while maintaining critical clearances in the engine bay. This optimized airflow path helps deliver cooler, denser air to the turbos for more consistent performance — even under extreme conditions.

Precision Silicone Hoses and Hardware:

Smooth bore, thick-walled silicone hoses provide unrestricted airflow and engine movement flexibility. CNC-machined, hard-anodised aluminium couplers and stainless-steel hardware ensure OE-quality fitment, corrosion resistance, and longevity.

Research & Development:

Pipercross utilises the latest 3D scanning, CAD, CFD simulation, and real-world dyno testing to create each AirMax system. Independent dyno testing on the G80 M3 demonstrated significant gains both stock and tuned — with the AirMax system resisting heat soak far better than the OEM intake under tuned conditions.

Airflow & Performance Testing Results:

• Airflow Gains: 785 CFM (RH) and 715 CFM (LH) maximum, compared to 770 CFM (RH) and 647 CFM (LH) OEM.

• Power Gains: +11 to +30 WHP and +16 to +35 Nm torque depending on vehicle tuning level.

• Heat Soak Resistance: Maintains consistent power output even under high engine bay temperatures with tuning applied.
