Owners of 2009-2016 E89 Z4 35i/35is 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 chargepipe can fail in several locations: the connection to the throttle body, the necks of the boost diverter valves, and along the plastic tube of the chargepipe itself. Any failure at these points will result in loss of boost and performance and may put the car into a limp mode.
This aluminum chargepipe is the fix for all of those 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.
- Direct replacement for factory chargepipe between intercooler and throttle body
- Increase throttle response and decreases turbo lag.
- CNC machined fittings and flanges
- Compatible with factory diverter valves or aftermarket diverter valves.
- Lightweight High Grade 6061 Aluminum Piping.
- Retains factory-style o-ring for a leak-free seal to throttle
- Deletes diverter valve sound baffle, which causes turbulence in the factory pipe
- Includes all hardware for complete installation.
- Limited Lifetime Warranty.
The ER Z4 N54 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 N54 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.
The original factory diverter valves can also be re-used although we suggest replacing them with new or an upgraded design. The stock valves are made of plastic and can fail internally, prematurely diverting boosted air away from the intake. This will result in a loss of power. New or upgraded diverter valves are also available. A version of this chargepipe with a blow-off valve (BOV) is also available.
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 all 2009+ Z4 35i and 35is models. The factory pipe is 2-piece and this will replace the upper portion only (past the rubber accordion boot). The lower portion is not prone to failure.Notice of Emissions Non-Compliance.
