Air Intake Kit for Toyota Supra (1987-1992) 3.0L Turbo

High-Flow Air Intake Kit for 1987-1992 Toyota Supra (7M-GTE/MA70)

This 3-inch MAF sensor adapter and open-element air filter system directly replaces the restrictive factory air box to lower intake charge temperatures and increase volumetric efficiency.

The Stock MA70 Airbox Bottleneck

The factory Toyota air box on the 3.0L 7M-GTE was designed with NVH (Noise, Vibration, and Harshness) reduction as the primary engineering objective. Consequently, the OEM intake relies on narrow, baffled plastic routing that disrupts laminar airflow before it reaches the mass airflow (MAF) sensor and turbo compressor. Under sustained boost, this convoluted tract creates significant airflow restriction, exacerbating heat soak within the engine bay and inherently stifling the CT26 turbocharger's spool characteristics. This leads to sluggish throttle response, high intake air temperatures (IATs), and a noticeable plateau in upper-RPM horsepower output.

The Engineering Solution

This intake kit eliminates OEM restrictions by utilizing a precision-machined CNC aluminum 3-inch MAF sensor adapter. Aluminum construction guarantees a distortion-free mating surface against the MAF sensor, ensuring accurate airflow metering and preventing unmetered air leaks. Paired with a dual-layer, washable cotton-gauze cone filter, the system maximizes the surface area exposed to ambient air. The two-stage filtration medium balances critical particulate capture with high-velocity airflow, allowing the 7M-GTE to draw colder, denser air directly into the intake tract. The result is optimized throttle response, accelerated turbo spool, and a measurable increase in peak explosive horsepower and torque output.
