2015-2017 Subaru WRX / STI High Flow Cold Air Intake FAQ
Q1: What Subaru WRX and STI models does this cold air intake kit fit?
A1: This cold air intake kit is designed for 2015, 2016, and 2017 Subaru WRX (FA20DIT) and WRX STI (EJ257) models. Always confirm your engine type and intake layout before purchasing, as WRX and STI use different engine platforms and airflow requirements.
Q2: Will this intake fit a 2015 WRX 2.0L turbo?
A2: Yes, it is compatible with the 2015 Subaru WRX equipped with the FA20DIT 2.0L turbocharged engine. It is a direct bolt-on upgrade that replaces the factory airbox and intake tube.
Q3: Does this cold air intake fit a 2015-2017 Subaru STI?
A3: Yes, it fits 2015-2017 Subaru WRX STI models with the EJ257 2.5L turbo engine. However, always verify sensor layout and intake routing before installation, as STI and WRX configurations differ.
Q4: What is the difference between WRX and STI fitment for this intake?
A4: The WRX uses a FA20DIT engine with different airflow and turbo inlet geometry, while the STI uses an EJ257 engine with a different throttle body and intake routing. This intake kit is designed to support both platforms, but correct installation depends on matching the proper configuration.
Q5: Does this intake require a tune on WRX or STI?
A5: A tune is not strictly required for basic installation, but a professional ECU tune is highly recommended for best performance. The WRX FA20DIT in particular benefits from tuning to optimize air-fuel ratios and boost response.
Q6: How much horsepower does a cold air intake add to a WRX or STI?
A6: Typical gains range from 5-15 horsepower depending on supporting modifications and tuning. The biggest improvement is usually faster turbo spool, improved throttle response, and stronger induction sound rather than peak horsepower alone.
Q7: Will this intake improve turbo spool and throttle response?
A7: Yes, the high-flow design reduces intake restriction, allowing the turbo to spool slightly faster and improving throttle response, especially in mid-range RPM conditions.
Q8: Will this intake cause a check engine light (CEL)?
A8: A properly installed intake should not trigger a CEL. Issues usually come from loose clamps, improper MAF sensor installation, or air leaks in the intake system.
Q9: Is this intake MAF or MAP sensor compatible?
A9: The Subaru WRX (FA20DIT) uses a MAF-based system, so correct sensor placement is critical. Ensure the MAF sensor is installed in the correct orientation to avoid drivability issues or incorrect air readings.
Q10: Will this intake make my WRX or STI louder?
A10: Yes, you will notice significantly louder turbo spool, blow-off valve sounds, and overall induction noise, especially under acceleration.
Q11: Is this considered a true cold air intake or short ram intake?
A11: This kit is designed as a high-flow cold air intake system with heat shielding to reduce engine bay heat exposure and improve air density compared to stock intake systems.
Q12: Can I install this intake myself?
A12: Yes, installation is typically straightforward and can be completed in about 45–90 minutes using basic hand tools. No cutting or permanent modification is required.
Q13: Is the air filter reusable and washable?
A13: Yes, the included performance air filter is washable and reusable. Regular cleaning helps maintain airflow efficiency and long-term performance.
Q14: Will this intake cause heat soak issues?
A14: Some heat soak may occur in traffic or idle conditions, but the heat shield design helps reduce hot air exposure compared to an open filter setup.
Q15: What should I check after installing the intake?
A15: After installation, check all clamps, MAF sensor connections, and couplers for air leaks. Ensure the intake is securely mounted and does not contact any moving or hot engine components.
