SYMS RAM AIR BOX SYSTEM FOR TOYOTA GR86 ZN8 SUBARU BRZ ZD8 Y2000EG037

Here are some benefits and advantages you can expect (or hope) when installing the SYMS Ram Air Box System (Y2000EG037) on a Toyota GR86 ZN8 / Subaru BRZ ZD8:

What the SYMS Ram Air Box System is

Before going into benefits, here’s what this system claims to do (from product descriptions):

• It replaces the factory airbox and resonator assembly with a carbon fiber airbox + a redesigned duct/air path that maximizes intake duct size within limited space.  
• It aims to introduce “ram air” — i.e. taking advantage of the vehicle’s forward motion to force higher-pressure (denser) air into the intake system.  
• It is designed to be compatible with the factory ECU tuning (i.e. no mandatory retune) within the correction/flexibility range of the stock ECU.  
• It uses carbon (or carbon composite) to combine performance benefits with aesthetic/weight advantages.  

Given that, here are the advantages (and caveats) you might see.

Potential Benefits & Advantages

1. Increased Airflow / Improved Volumetric Efficiency
   
• Because the ducting and internal geometry are optimized to reduce airflow restrictions, more air can reach the engine more efficiently.  
• The “ram air” effect (at higher speeds) could help slightly increase the density (mass) of intake air, giving a small “boost” effect.  
• With more air (if matched with proper fueling), the engine can produce more torque and power, especially in the upper RPM band.  
2. Better Throttle Response / Reduced Lag
   
• Because the intake path is more direct / less restrictive, the throttle (and engine) can respond more quickly to changes in load, especially at higher engine speeds.  
• Less “intake lag” or delay between throttle input and air arriving in the combustion chambers.
3. Aesthetic & Weight Advantages
   
• The use of carbon fiber material gives a premium look under the hood (carbon weave) which appeals to enthusiasts.  
• Carbon fiber (or composite) is typically lighter than stock materials (plastic or metal), so there may be a small weight savings (though likely minor in the broader weight budget).
4. Maintains Stock ECU / No Mandatory Retune
   
• One of its selling points is that it is usable within the correction range of the factory ECU (i.e., you may not need to reprogram or remap to take advantage).  
• This means installation is more “bolt-on” friendly and you don’t necessarily have to risk messing with your stock engine calibration.
5. Better Sound / Induction Noise
   
• Many aftermarket intake/ram air systems change the aural character of the engine (more intake “growl” or induction sound). While this is more subjective, it is a benefit some owners seek.
• Because resonators (or factory sound-damping parts) may be replaced or altered, you might hear more of the intake noise. (Note: this is also a potential drawback in noise-sensitive settings.)

Caveats, Limitations & What to Watch Out For

It’s important to temper expectations. Here are things to be cautious about:

• Modest Power Gains: While the claims suggest improvements, the actual horsepower/torque gains are often modest on a normally aspirated (non-forced induction) engine. Many intake upgrades yield small gains (few percent) unless the rest of the system (camshaft, exhaust, tuning) is also upgraded.
• Heat Soak / Intake Temperature: If the airbox is not sufficiently isolated from engine heat or if the ducting allows hot under-hood air ingress, performance could suffer due to warmer intake air. Some “cold air / ram air” designs struggle when the engine bay is hot.
• Speed-Dependent Benefit: The “ram air” effect is more effective at higher speeds. At lower speeds (city driving), the effect is minimal.
• Filter & Maintenance: Aftermarket systems may require more frequent cleaning or servicing of filters.
• Fitment & Packaging Constraints: Because the engine bay space is tight, routing, clearance, and making sure there’s no interference with other parts are critical.
• Warranty / Emissions Compliance: In some jurisdictions, aftermarket intake modifications may affect emissions legality or warranty status (depending on local regulations).
• ECU Limits: Even though it claims compatibility with the stock ECU, the stock engine control unit has limits on how much additional airflow/fuel it can adjust before requiring a reflash or supporting modifications (fuel injectors, etc.).
• Noise / Drone: Some setups may introduce undesirable induction noise or drone under certain RPM loads.

Summary

In summary, installing the SYMS Ram Air Box System (Y2000EG037) on a GR86 / BRZ can give you:

• Better airflow and possibly improved volumetric efficiency
• Slight boost (ram-air effect) at speed
• Quicker throttle response
• Cleaner, premium look with carbon fiber
• Maintainability with stock ECU (no required tune)
• Enhanced induction sound

However, don’t expect huge power leaps without complementary upgrades, and be mindful of intake temperature, fitment, and regulatory/warranty considerations.
