What’s Included

The package combines:

• Wagner Tuning EVO2 Competition Intercooler
• Wagner Tuning N55 catless downpipe
• Reinforced silicone hoses
• Aluminium adapter
• Mounting hardware
• Installation instructions

EVO2 Competition Intercooler

The EVO2 Competition intercooler uses a larger high-performance core than the standard unit, designed to improve charge-air cooling and resist heat soak during repeated hard use.

Key benefits include:

• Increased intercooler surface area
• Greater charge-air volume
• Improved intake-air temperature control
• Better thermal consistency under sustained load
• Reduced heat soak
• Performance-focused construction

The larger core helps keep intake temperatures more stable, particularly on tuned or heavily used N55-powered cars.

Competition Core Design

The intercooler uses a high-performance tube-fin core with internal turbulators and cast aluminium end tanks.

These features are designed to improve heat transfer and airflow distribution through the core while maintaining strong flow characteristics.

N55 Catless Downpipe

The package also includes a catless N55 downpipe designed to reduce exhaust restriction after the turbocharger.

Key features include:

• Stainless steel construction
• Catless design
• Improved exhaust gas flow
• Reduced back pressure
• Reduced thermal load on the turbocharger
• Designed for performance and motorsport applications

Improved Cooling & Exhaust Flow

By combining an uprated intercooler with a freer-flowing downpipe, the package addresses both the intake and exhaust sides of the turbocharger system.

This can help support:

• More consistent performance
• Improved thermal management
• Reduced intercooler heat soak
• Improved exhaust flow
• Reduced turbocharger back pressure
• Better overall response

Vehicle Fitment

Designed for selected N55-powered BMW E-Series models including:

• BMW E82 135i
• BMW E88 135i
• BMW E90 335i / 335xi
• BMW E91 335i / 335xi
• BMW E92 335i / 335xi
• BMW E93 335i / 335xi

Exact engine and production-year compatibility should be confirmed before ordering.

Important Road-Use Notice

The supplied downpipe does not contain a catalytic converter.

This component is not intended for road use and is suitable for racing / motorsport applications only.

Removing the catalytic converter can also trigger emissions-related warnings or DME fault codes depending on vehicle configuration.

Professional Installation Recommended

Professional installation is strongly recommended.

All intercooler connections, exhaust joints, lambda sensor fittings and mounting points should be checked carefully after installation.
