The Lexus IS300 is a favorite among car enthusiasts for its blend of performance and luxury. One of the most effective ways to enhance its power is through an intake and exhaust combo. This article will guide you through achieving an impressive 30+ horsepower increase for around $1,200.
Understanding the Importance of Intake and Exhaust Systems
The intake and exhaust systems are crucial for any vehicle’s performance. They work together to ensure that the engine breathes efficiently, allowing for better combustion and power output.
How the Intake System Works
The intake system is responsible for bringing air into the engine. A high-performance intake system allows for increased airflow, which can lead to improved throttle response and horsepower.
The Role of the Exhaust System
The exhaust system expels gases produced during combustion. A free-flowing exhaust system reduces back pressure, allowing the engine to expel exhaust gases more efficiently, which can also contribute to increased horsepower.
Recommended Intake and Exhaust Components
To achieve the desired horsepower increase, consider the following components:
- Cold Air Intake System: Look for brands like AEM or Injen, known for their quality and performance.
- Cat-Back Exhaust System: Brands such as Borla or MagnaFlow offer systems that enhance sound and performance.
Installation Process
Installing an intake and exhaust system can be a rewarding DIY project. Here’s a step-by-step guide:
- Tools Needed: Basic hand tools, jack stands, and safety goggles.
- Remove the Stock Intake: Disconnect the battery, unclamp the intake tubing, and remove the airbox.
- Install the New Intake: Follow the manufacturer’s instructions for fitting the new cold air intake.
- Remove the Stock Exhaust: Unbolt the exhaust system starting from the rear and working forward.
- Install the New Exhaust: Fit the new cat-back exhaust system, ensuring all connections are secure.
Tuning Your Lexus IS300
After installing the intake and exhaust systems, it’s essential to tune your vehicle to maximize performance. A proper tune can adjust the air-fuel ratio and ignition timing, allowing your engine to run efficiently with the new components.
Choosing the Right Tune
Consider using an ECU tuning service or a handheld tuner. Popular options include:
- ECU Flashing: A professional service that modifies your engine’s software.
- Handheld Tuners: Devices like the SCT X4 allow for easy adjustments and monitoring.
Testing Performance Gains
Once everything is installed and tuned, it’s time to test your performance gains. A dynamometer (dyno) will give you the most accurate measurement of horsepower and torque.
What to Expect
With the right setup, you can expect to see a gain of 30+ horsepower. This increase will not only enhance acceleration but also improve overall driving enjoyment.
Conclusion
Upgrading your Lexus IS300 with a quality intake and exhaust combo is a cost-effective way to achieve significant performance gains. For around $1,200, you can enjoy an exhilarating driving experience with a boost in horsepower.
Always remember to follow local regulations regarding emissions and modifications. Happy driving!
