PTNHZ Short Ram Cold Air Intake System w/Heat Shield Compatible With Honda Civic 1.5L Turbo 2016-2024
This intake system is designed specifically for Honda Civics with 1.5L turbo engines, excluding the Si, and offers a simple yet effective upgrade to improve airflow. Compared to turbo kits like the TD025 Turbocharger, which focus on forced induction, this intake enhances the engine’s breathing, resulting in better throttle response and potential horsepower gains. The use of aluminum and iron construction provides durability and high-temperature resistance. Installation is straightforward, making it suitable for DIY enthusiasts, but it won’t add as much power as a turbo upgrade. Additionally, regular cleaning is required every 20,000 km, and replacement around 60,000 km. For owners seeking a cost-effective way to boost throttle response without extensive modifications, this intake is a good choice, but it won’t deliver the dramatic power increase of turbo systems.
bestFor: Owners of Honda Civics with non-Si models looking to improve throttle response and airflow efficiency.
notIdealFor: Si owners or those wanting significant horsepower increases via forced induction.
pros: Improves throttle response, durable aluminum and iron construction, easy bolt-on installation, high-temperature resistance.
cons: Not compatible with Si models, limited power gains compared to turbo kits, requires regular cleaning and maintenance.

- Sturdy aluminum and iron materials
- Easy to install with no modifications needed
- High temperature and pressure resistance
Cons:- Not compatible with Si models
- Limited power gains
- Requires regular cleaning and maintenance
Best for: Owners of Honda Civic 1.5L turbo models (excluding Si) seeking better throttle response and airflow.

This turbo kit offers a direct OEM-style replacement for Honda Civics with the TD025L4B turbo, making it a practical choice for those needing a reliable turbo upgrade without extensive modifications. Compared to the maXpeedingrods T3 T4 Turbo, which is a larger, more aggressive setup, this kit maintains a focus on stock or slightly upgraded performance suitable for daily driving. It includes an actuator and gasket, simplifying replacement, but it does not fit Si models, limiting its versatility for high-performance builds. The durable alloy construction and included components promote longevity, yet some users report that the performance gains are modest unless paired with supporting upgrades. This kit makes sense for owners seeking a straightforward turbo replacement that preserves OEM integrity but isn’t aimed at high-horsepower applications.
bestFor: Honda Civic owners with 1.5L engines needing a reliable OEM-style turbo replacement.

How We Picked
I evaluated these turbo kits based on a combination of performance, build quality, ease of installation, and overall value. Kits that include comprehensive components like actuators, gaskets, and intercoolers ranked higher, as they provide a more complete upgrade experience. I also considered the compatibility with various model years of Honda Civic Si to ensure the recommendations suit most users. Cost was weighed against potential power gains and reliability, favoring options that deliver consistent performance without excessive complexity. The ranking reflects a balance between affordability, ease of use, and capability for sustained, reliable power upgrades.Factors to Consider When Choosing Best Turbo Kits For Honda Civic Si
Choosing the best turbo kit for your Honda Civic Si involves understanding several key factors. Beyond raw power, considerations like ease of installation, compatibility, durability, and the overall upgrade package matter significantly. Making a decision based solely on price or brand can lead to issues down the line; instead, evaluating how each kit aligns with your goals and existing setup ensures a smarter upgrade. The following factors will help clarify what to prioritize when selecting a turbo kit for your Civic Si.Performance Goals and Power Potential
Before selecting a turbo kit, define what you want from your Civic Si. Are you seeking modest improvements for daily driving or aiming for high horsepower for racing? Kits with larger turbos and intercoolers generally support higher power levels but may require additional supporting modifications. Understanding your goals helps narrow choices, preventing over- or under-investment in features you don’t need.
Ease of Installation and Compatibility
Turbo kits vary significantly in complexity. Some come as complete bolt-on assemblies, while others require custom modifications. Ensuring the kit is compatible with your specific model year and engine type avoids costly mistakes. Kits with detailed instructions and included components like gaskets and actuators simplify installation, saving time and reducing the risk of errors.
Build Quality and Durability
Investing in a durable, well-made turbo kit reduces the risk of failures and costly repairs. High-quality materials, reliable turbines, and robust housings matter, especially if you plan to push your Civic Si regularly. Cheaper options may save money upfront but often lack longevity, leading to more expenses over time.
Supporting Modifications and Upgrades
Turbocharging often requires supporting upgrades such as clutch kits, fuel system enhancements, and engine tuning. Consider whether the kit includes or is compatible with these components. Failing to upgrade supporting parts can lead to reliability issues or limited performance gains, so plan your build holistically.
Cost and Value
Price varies widely among turbo kits. While a higher cost often correlates with better components and performance, some budget options can deliver good results with proper setup. Balance your budget against your goals, and remember that investing more upfront can reduce future repairs and upgrades. Focus on value—what you get for the price—rather than cost alone.
Frequently Asked Questions
Will installing a turbo kit void my Honda Civic Si’s warranty?
Installing a turbo kit can void certain aspects of your vehicle’s warranty, especially if it causes damage or if your warranty explicitly excludes modifications. However, some manufacturers offer warranties that cover aftermarket parts or allow modifications within certain limits. It’s wise to check your warranty terms and consider professional installation to minimize potential issues.
Do I need to upgrade my clutch when installing a turbo kit?
Yes, upgrading your clutch is often necessary when adding a turbo, especially for higher boost levels. The increased power and torque can strain stock clutches, leading to slipping or failure. A clutch upgrade ensures your drivetrain can handle the additional power reliably, making your turbo experience smoother and more durable.
Can I install a turbo kit on my own, or do I need a professional?
While some experienced DIY enthusiasts can install turbo kits themselves, many installations are complex and require specialized tools and knowledge. Incorrect installation can lead to poor performance or engine damage. For most users, professional installation is recommended to ensure proper setup, tuning, and safety.
How much horsepower can I expect from a typical turbo kit for Honda Civic Si?
Most turbo kits for Civic Si models provide a range of 50 to 150 additional horsepower, depending on the kit and supporting modifications. Achieving higher power levels may require upgraded fuel systems, intercoolers, and engine tuning. Always match your expectations with the kit’s specifications and your overall build plan.
What are the signs that my turbo kit needs maintenance or repairs?
Common signs include reduced boost pressure, unusual exhaust smoke, strange noises like whistling or whining, or a noticeable drop in power. Regular inspection of connections, hoses, and the turbo unit itself can prevent failures. Proper maintenance extends the lifespan of your turbo kit and ensures consistent performance.
Conclusion
The best overall choice for most Honda Civic Si owners is the TD025L4B Complete Turbo Kit, offering a balanced mix of power, reliability, and ease of installation. Budget-conscious buyers may prefer the ApplianPar Turbocharger Turbo Air Pipe Joint for simple, cost-effective upgrades, but should be prepared for additional modifications. Enthusiasts seeking premium performance and durability will find the Action Clutch Stage 1 HD Clutch Kit paired with a turbo upgrade to be a solid investment. For beginners, a kit with comprehensive instructions and included components will reduce headaches, while experienced tuners may opt for high-capacity kits supporting significant power gains. By aligning your choice with your skill level, budget, and performance goals, you can make a smart upgrade that transforms your Civic Si.
