The S55 engine, found in various BMW models, is known for its performance and tuning potential. One of the most effective upgrades for enhancing both power and reliability is the installation of an aftermarket intercooler. In this article, we will explore the process of installing the Evolution Racewerks intercooler on the S55 engine, which can significantly improve performance for around $1,200.
Why Upgrade to an Aftermarket Intercooler?
Upgrading the intercooler is essential for several reasons:
- Improved Cooling Efficiency: An aftermarket intercooler typically features a larger core and better airflow, which helps maintain lower intake temperatures.
- Increased Power Output: Cooler air is denser, allowing for more oxygen to enter the engine, which can lead to higher power levels.
- Enhanced Reliability: By reducing the temperature of the intake air, the engine can operate more efficiently, leading to improved reliability over time.
Tools and Materials Required
Before starting the installation, ensure you have the following tools and materials:
- Socket set
- Torque wrench
- Flathead and Phillips screwdrivers
- Intercooler piping kit (if necessary)
- Evolution Racewerks intercooler
- Silicone couplers
- Clamps
- Heat-resistant spray (optional)
Step-by-Step Installation Guide
1. Prepare the Vehicle
Start by ensuring the vehicle is parked on a flat surface and the engine is cool. Disconnect the battery to prevent any electrical issues during the installation process.
2. Remove the Front Bumper
To access the intercooler, you will need to remove the front bumper. This typically involves:
- Unscrewing the screws and clips securing the bumper.
- Carefully pulling the bumper away from the vehicle, ensuring not to damage any clips.
- Disconnecting any wiring harnesses attached to the bumper.
3. Remove the Stock Intercooler
Once the bumper is off, locate the stock intercooler. Remove the piping connected to the intercooler by loosening the clamps and carefully pulling off the hoses. Then, unbolt the intercooler from its mounting points.
4. Install the Evolution Racewerks Intercooler
Position the new intercooler in place and secure it with the provided mounting hardware. Make sure it fits snugly and aligns properly with the existing piping.
5. Connect the Piping
Attach the intercooler piping to the new intercooler. Use silicone couplers and clamps to ensure a tight seal. Double-check that all connections are secure and free from leaks.
6. Reinstall the Front Bumper
Once the intercooler and piping are installed, carefully reinstall the front bumper. Reconnect any wiring harnesses and secure the bumper with screws and clips.
7. Reconnect the Battery and Test
Reconnect the battery and start the engine. Allow it to idle for a few minutes while checking for any leaks or issues. Take the car for a test drive to ensure everything is functioning correctly.
Performance Gains and Benefits
After installing the Evolution Racewerks intercooler, many drivers report noticeable improvements in performance, including:
- Increased horsepower and torque.
- Better throttle response.
- More consistent performance during spirited driving or track use.
Conclusion
Upgrading to the Evolution Racewerks intercooler on the S55 engine is a worthwhile investment for those looking to enhance both power and reliability. With a budget of around $1,200, this upgrade provides significant performance benefits, making it a popular choice among enthusiasts.
