EWP & FAN DIGITAL CONTROLLER

The updated V2 LCD Digital Controller how has two specific functions. This unique Controller will now manage the operation of the EWP by varying the speed of the EWP in response to the temperature of the engine and manage control of your electric engine fan. The Controller has a push-button on the facia panel that offers target temperatures Singular degrees from 40C (104F)to 110C (230F).

Generally, higher engine temperature will offer improved fuel efficiency and lower engine temperature more power. The LCD Digital Controller will now operate the engines electric fan automatically once the engine has reached +3c above the target temperature. A significant benefit too is the Controller allows the EWP to run on after ignition shutdown to reduce heat soak. It is recommended that engine operational temperatures be checked with manufacturer.

Direct Fit and good quality
Color: Single Slat Gloss Black, Size: 2002-2005 E46
For anyone that has owned an E46 knows that even the stock kidney grills are brittle plastic. This aftermarket is about the same quality as stock. It is a direct fit and has the clips where they are supposed to be to keep them in place. The look is also pretty nice. This one is all black and actually looks nice on my black E46. I would recommend especially for the price and shipping was fast.
