Pros and Cons of Buying a Subaru WRX STI Intake Cam Gear for Model Years 2004-2018

Introduction:

The Subaru WRX STI intake cam gear is an essential performance part for Subaru enthusiasts seeking to enhance their vehicle's power output and engine responsiveness. This component is a crucial part of the engine's Variable Valve Control System (AVCS). In this analysis, we will discuss the key advantages and disadvantages of purchasing a Subaru 16622AA001 intake cam gear for model years 2004-2018.

Pros:

1. Increased horsepower and torque: Upgrading the intake cam gear can lead to substantial power gains, typically between 10-20 horsepower and 15-25 lb-ft of torque, depending on the specific engine configuration and tuning.

2. Enhanced engine responsiveness: The new camshaft design provides faster valve opening and closing, resulting in improved throttle response and a more engaging driving experience.

3. Improved fuel efficiency: Although not a primary benefit, some users report modest improvements in fuel economy due to the engine's increased efficiency.

4. Better high-end power: The upgraded camshaft allows for improved engine breathing at higher RPMs, yielding stronger top-end power.

5. Durability and reliability: Subaru's engineering and manufacturing expertise ensure that the OEM camshaft is of high quality and designed to last.

Cons:

1. Complex installation process: Installing the new camshaft requires significant expertise and the proper tools, including a camshaft position sensor alignment tool and a valve clearance tool. This process may be best left to professional mechanics or experienced DIY enthusiasts.

2. Cost: The price of the intake cam gear may be a significant investment for some, especially when considering the cost of other potential modifications like exhaust systems or ECU upgrades.

3. Potential power loss: In some cases, the new camshaft may result in a slight loss of low-end torque due to the faster valve opening and closing. This trade-off is generally acceptable for those seeking increased power and engine responsiveness.

4. Requires additional modifications: To fully realize the potential benefits of the new camshaft, other modifications like an ECU tune or exhaust system may be necessary. These additional costs should be considered when budgeting for the upgrade.

5. Potential engine noise: The upgraded camshaft may result in increased engine noise, which some enthusiasts may find appealing but others may find bothersome.

Conclusion:

In conclusion, the Subaru WRX STI intake cam gear upgrade offers substantial benefits for those seeking increased power, improved engine responsiveness, and a more engaging driving experience. However, the complex installation process, potential power loss, and additional costs associated with the upgrade should be carefully considered before making a purchase. Ultimately, the decision to invest in this upgrade depends on the individual's priorities, budget, and technical expertise.
