You have now completed the installation of the Eventuri F4X M135i
M235i Intake System.
Please take all necessary precautions while installing this system.
Eventuri cannot take responsibility for an incorrectly installed intake or
any damage caused during installation.

Instructions :: SUPPLIMENTARY – RESTRICTOR PLATE GUIDEIn the intake kit you will find this plate. It is only to be used in some instances where thecheck engine light is triggered after using the intake and the error code is for Lean air
fuel mixture or too much flow detected by the MAF.
This plate restricts some of the flow to bring it within the tolerance of the factory MAF
parameters. It is not required in all instances therefore it has not been pre-installed.
