Evolution Racewerks Chargepipe Kit - E82 135i, E9X 335i (N55) 11-13

Owners of 2011-2013 N55 E82 135i and E90/E92 335i BMW models will find out that the plastic intake chargepipe going to the throttle body is a weak point that will eventually fail, even on fully stock, unmodified cars. The N55 chargepipe most commonly fails at the connection to the throttle body and a tremendous loss in power usually follows (sometimes with limp mode activated).

This aluminum chargepipe is the fix for these issues and comes with a lifetime warranty so you will never have to buy another chargepipe again. Evolution Racewerks are experts in the turbo tuning industry and they have designed this pipe to be a direct replacement for the factory piece and as a performance upgrade as well. Three finishes are offered: mirror polished, brushed aluminum silver, and black hardcoat anodize.

Key Features:

• Direct replacement for factory chargepipe between intercooler and throttle body
• Increase throttle response and decreases turbo lag.
• CNC machined fittings and flanges
• Lightweight High Grade 6061 Aluminum Piping.
• Retains factory-style o-ring for a leak-free seal to throttle
• Includes all hardware for complete installation.
• Limited Lifetime Warranty.

The ER N55 Chargepipe installs easily thanks to factory-type connectors and precise CNC machining. Other charge pipes use silicone hoses and hose clamps which are common in the industry but do not seal tight enough on the BMW N55 engine. The original retaining clip can be re-used from the throttle-body connection but we recommend a new one.

For tuners, this pipe can be provided with one or two 1/8" NPT threaded bungs. This provides an excellent injection port for methanol, nitrous, or to use for actual vacuum readings. Plugs are provided when bungs are not being used. The pipe is also available without NPT bungs for a fully factory appearance.

Three finish options are offered:
mirror polish to highlight your chargepipe upgrade
brushed silver for a high quality look
black hardcoat anodize provides the best strength, protection, and an original appearance. The hardcoat actually makes the aluminum stronger, further reducing the chance of failure.

This chargepipe is for 2011-2013 135i, 135is, 335i, and 335xi models with the N55 engine.
