Extreme Turbo Systems 3.5" MAF Housing w/ 3.0" to 3.5" Stock Turbo Intake Coupler Subaru WRX 2015-2021 - 200-40-INT-009

Extreme Turbo Systems 200-40-INT-009 MAF Housing Upgrade

If you’ve upgraded your turbo on your 2015+ Subaru WRX and are pushing the limits of your factory MAF, it’s time to consider the Extreme Turbo Systems 200-40-INT-009 MAF Housing. This is the same high-performance MAF housing we use in our turbo kits, designed to enhance airflow and support your tuning needs.

Fitment

  • Subaru WRX 2015-2021

Why Upgrade?

When you’re making serious power, the stock MAF can become a bottleneck. The 200-40-INT-009 allows for greater airflow, ensuring your engine gets the air it needs to perform at its best. This is particularly crucial for WRX owners who have made substantial upgrades to their turbo systems.

Installation Notes

  • Optional couplers are available for adapting to your stock intake or your turbo kit intake.
  • A tune is mandatory when installing this MAF housing, as the MAF will need to be re-scaled to accommodate the larger size.

Customer Feedback

Subaru WRX owners have reported noticeable improvements in throttle response and overall engine performance after installing the 200-40-INT-009. One owner mentioned, “After installing this MAF housing on my 2019 WRX, I could feel the difference right away. It paired perfectly with my upgraded turbo and the tuning was straightforward.”

Technical Specifications

  • Part Number: 200-40-INT-009
  • Material: High-quality aluminum
  • Finish: Anodized for durability
  • Weight: Lightweight design for performance

With the Extreme Turbo Systems 200-40-INT-009, you’re not just upgrading a part; you’re making a smart investment in your Subaru WRX’s performance. Don’t let a restrictive MAF hold you back from achieving your power goals.
