Are you a proud owner of a BMW E36 and looking to optimize its performance? One modification that you may consider is deleting the secondary air pump. In this article, we will explore the benefits, process, and potential implications of this modification.
What is the Secondary Air Pump?
The secondary air pump is an emissions control device found in many vehicles, including the E36. Its purpose is to inject fresh air into the exhaust system during cold starts. This helps to reduce harmful emissions until the engine reaches its optimal operating temperature.
Why Consider Deleting the Secondary Air Pump?
There are several reasons why E36 enthusiasts may choose to delete the secondary air pump. Firstly, removing this component can improve engine performance by reducing backpressure in the exhaust system. This can lead to increased horsepower and torque.
Furthermore, the secondary air pump is known to be a common source of failure in the E36. By deleting it, you eliminate the risk of potential issues arising from a malfunctioning pump. This can save you time, money, and headaches in the long run.
The Process of Deleting the Secondary Air Pump
To delete the secondary air pump in your E36, you will need to follow a few simple steps:
Step 1: Gather the Necessary Tools
Before you begin, make sure you have the required tools, including wrenches, pliers, and a socket set. Additionally, it is recommended to have a secondary air pump delete kit specifically designed for the E36.
Step 2: Disconnect the Battery
For safety purposes, disconnect the negative terminal of the battery to prevent any electrical mishaps during the process.
Step 3: Locate the Secondary Air Pump
The secondary air pump is typically located near the front of the engine bay. Refer to your vehicle’s manual or online resources to find its exact location.
Step 4: Remove the Pump
Using the appropriate tools, carefully disconnect the pump from the mounting brackets and detach any electrical connections. Take your time to avoid damaging any surrounding components.
Step 5: Install the Delete Kit
With the secondary air pump removed, follow the instructions provided with the delete kit to install the necessary plugs and block-off plates.
Step 6: Reconnect the Battery
Once the delete kit is installed, reconnect the negative terminal of the battery.
Implications and Considerations
It is important to note that deleting the secondary air pump may have legal implications in some regions. Ensure that you are aware of the local emissions regulations and the potential consequences of non-compliance.
Additionally, removing the secondary air pump may trigger a check engine light or cause your vehicle to fail emissions tests. To mitigate these issues, you can install an O2 sensor simulator or an aftermarket engine management system.
In Conclusion
Deleting the secondary air pump in your E36 can offer performance benefits and reduce the risk of future problems. However, it is crucial to consider the legal implications and potential modifications required to ensure compliance and optimal engine performance. If you are unsure about the process, it is always recommended to consult with a professional mechanic or automotive specialist.
