K20 Racing Inlet Manifold 70mm EP3/ DC5

K20 Racing Inlet Manifold 70mm EP3/ DC5

The K20 Racing Inlet Manifold 70mm is a high-performance aftermarket part designed for the Honda K20 engine.

Commonly found in vehicles like the Honda Civic EP3 (2002-2005) and Honda Integra DC5 (2001-2006). 

This inlet manifold is designed to improve airflow to the engine, resulting in better throttle response and potential performance gains, particularly in higher RPM ranges.

Here are some key features and benefits of the K20 Racing Inlet Manifold (70mm):

1. Larger Throttle Body Opening (70mm): The 70mm throttle body opening is larger than the stock manifold, allowing for more air to flow into the engine. This can lead to an increase in horsepower and torque, especially when paired with other performance modifications.

2. Improved Airflow: The manifold is typically designed with smoother internal channels and more optimized runner lengths, which improves airflow efficiency. This results in better volumetric efficiency, particularly at higher engine speeds.

3. Suitable for Performance Builds: This manifold is typically intended for modified or tuned K20 engines, where higher power outputs are desired. It’s ideal for builds with performance camshafts, headwork, or forced induction.

4. Direct Fit for EP3/DC5: The manifold is designed as a direct bolt-on upgrade for the EP3 Civic and DC5 Integra with the K20 engine, making installation relatively straightforward.

5. Tuning Potential: With the increased airflow and improved intake characteristics, a tune is usually required to optimize the engine’s performance, fuel delivery, and ignition timing for the best results.

Before installing a K20 Racing Inlet Manifold, you may need to consider other supporting modifications such as a larger throttle body, aftermarket fuel injectors, or a remap for the ECU to fully realize the performance benefits.
