It Wagner Competition package EVO 3 is designed for those who want the most out of their BMW 135i (E82/E88) or 335(x)i (E90/E91/E92/E93) with N55 engine want to pick up. The package consists of a EVO 3 intercooler upgrade kit and a N55 downpipe kit without catalytic converter, which together ensure a significant performance improvement.
The EVO 3 intercooler has dimensions of 510 mm x 303 mm x 180 mm (stacked 20.65 L) and offers a 162% larger intake surface area and 182% more charge air volume compared to the standard intercooler. This effectively lowers the intake air temperature for improved engine performance and more responsive acceleration. The intercooler is equipped with a high-quality Tube Fin net with internal turbulators for optimal heat transfer and airflow. The cast aluminum end tanks have been optimized using CFD flow analysis to minimize back pressure. The inlets and outlets have been enlarged to Ø70 mm for maximum airflow. Weighing only 13.2 kg, the intercooler is both light and strong. An anti-corrosion coating with heat-conducting properties ensures durable, optimal cooling. The intercooler is tested up to 6 bar and is pressure-stable, and is installed plug and play with reinforced silicone hoses.
The N55 downpipe without catalytic converter is made of high quality stainless steel 1.4301 (SS304) and has a diameter of 76 mm for improved exhaust gas flow and a significant increase in torque and power. The downpipe is CAD-designed for a perfect fit, features 2 lambda sensor connections, and reduces the thermal load on the turbo.

Frequently Asked Questions
For which vehicles is this package suitable?
The package fits the BMW 135i (E82/E88) and 335(x)i (E90/E91/E92/E93) with N55 engine.
Does the downpipe have a catalytic converter?
No, this downpipe is designed without a catalytic converter, which reduces back pressure and improves performance.
Is installation complicated?
The intercooler is installed plug and play with reinforced silicone hoses as a replacement for the standard intercooler. It is advisable to modify the software to prevent error codes in the DME.
