hi,

I have a 06 e55. someone said that I should first make sure my car's cooling is working efficiently and that if not, i may be running with lower HP.

What are the important cooling components to check, how to check them and what are some of the basic cooling upgrades?

Thanks

 

Replace your Intercooler pump with a johnson CM30. Cheap easy to install if your pump is going out, which is highly likely, you will feed a difference.

 

Bosch 010 intercooler pump & a heat exchangers (couple of brands) should get you started

I would install a Johnson cm30 and split your cooling. We (BI Performance) have both parts in stock and I can give you a great price.

Pm me if interested.
