The Honda Prelude is a beloved sports coupe known for its performance and sleek design. For enthusiasts looking to boost their vehicle’s horsepower, upgrading the intake and exhaust systems is a popular and effective option. In this article, we will explore the best intake and exhaust upgrades for the Honda Prelude that can help achieve a significant horsepower increase of 15-20 HP.
Understanding Intake and Exhaust Systems
The intake system is responsible for bringing air into the engine, while the exhaust system expels gases produced during combustion. Upgrading these systems can enhance airflow, improve engine efficiency, and ultimately increase horsepower.
Best Intake Upgrades for Honda Prelude
When it comes to intake upgrades, several options can help maximize airflow and performance. Here are some of the best choices:
- Cold Air Intake Systems: These systems draw cooler air from outside the engine bay, increasing air density and improving combustion efficiency.
- Short Ram Intake: A short ram intake provides a direct path for air to enter the engine, resulting in quicker throttle response.
- High-Performance Air Filters: Upgrading to a high-flow air filter can improve filtration while allowing more air to enter the engine.
1. Cold Air Intake Systems
Cold air intakes are one of the most popular upgrades for the Honda Prelude. They typically consist of a longer intake tube that extends to the front of the vehicle, where cooler air is more readily available. This cooler air is denser, which can lead to better combustion and a noticeable increase in horsepower.
2. Short Ram Intake
A short ram intake is another excellent choice for those looking to improve performance. This type of intake is shorter than a cold air intake and is designed to provide a more direct airflow path. While it may not offer the same cooling benefits as a cold air intake, it can still enhance throttle response and overall engine performance.
3. High-Performance Air Filters
Replacing the factory air filter with a high-performance option can also yield significant benefits. These filters are designed to allow for greater airflow while still providing excellent filtration. This upgrade is often the easiest and most cost-effective way to improve engine performance.
Best Exhaust Upgrades for Honda Prelude
Just like the intake system, upgrading the exhaust can lead to significant performance gains. Here are some of the best exhaust upgrades for the Honda Prelude:
- Cat-Back Exhaust Systems: These systems replace the entire exhaust from the catalytic converter back, improving exhaust flow and sound.
- Headers: Upgrading stock headers to performance headers can improve exhaust scavenging and reduce back pressure.
- High-Flow Catalytic Converters: These converters allow for better exhaust flow while still meeting emissions standards.
1. Cat-Back Exhaust Systems
Cat-back exhaust systems are a comprehensive upgrade that replaces all components from the catalytic converter back to the exhaust tips. This upgrade not only improves exhaust flow but also enhances the sound of the vehicle, giving it a more aggressive tone. Many cat-back systems are designed to optimize performance and can add several horsepower.
2. Headers
Upgrading to performance headers can significantly improve exhaust flow and reduce back pressure. Stock headers are often restrictive, and by replacing them with aftermarket options, you can enhance the engine’s ability to expel exhaust gases. This can lead to a noticeable increase in horsepower and torque.
3. High-Flow Catalytic Converters
High-flow catalytic converters are designed to allow for better exhaust flow while still meeting emissions regulations. Upgrading to a high-flow cat can help improve overall exhaust efficiency, contributing to increased horsepower. It’s an excellent option for those looking to enhance their exhaust system without sacrificing compliance.
Combining Intake and Exhaust Upgrades
For the best results, consider combining both intake and exhaust upgrades. By improving airflow into and out of the engine, you can maximize performance gains. Here are some tips for achieving the best results:
- Choose compatible parts to ensure optimal performance.
- Consider tuning your engine after upgrades to maximize potential gains.
- Regular maintenance is essential to keep your upgrades performing at their best.
Conclusion
Upgrading the intake and exhaust systems of your Honda Prelude can lead to a significant increase in horsepower, enhancing the overall driving experience. By selecting the right components and ensuring proper installation, you can achieve a horsepower increase of 15-20 HP. Whether you opt for a cold air intake, cat-back exhaust, or high-performance filters, these upgrades will help unlock your Prelude’s full potential.
