VTT Modular Silicone/Billet Intake System – Toyota A90/91 Supra (B58TU Engine)

VTT is proud to announce our Modular Silicone/Billet Intake System for the A90/91 Toyota Supra with the B58TU engine.

After countless hours of testing and fitting, we’ve engineered an intake that delivers both optimized airflow and OEM-level fitment.

Why Upgrade?

The factory Supra airbox is efficient, but the intake tract to the turbo is a problem area. It’s full of twists, turns, and accordion bellows that disrupt airflow, plus a built-in silencer that restricts performance by bypassing air simply to quiet intake sound.

By replacing these with our 3″–3.5″ free-flowing silicone intake tube, paired with your choice of:

• The stock airbox (for factory sound/appearance),

• Our 6″ cone filter with built-in velocity stack (for maximum airflow and sound), or

• Our Carbon Fiber Airbox Lid with high-flow panel filter,

…you remove restrictions and create a smooth, optimized air path straight to the turbo.

Our testing shows that the stock airbox supports up to ~700WHP. Beyond that, we recommend upgrading to the 6″ cone system for maximum efficiency.

Modular by Design

This system is fully modular, allowing you to configure it for your exact goals.

Options:

1. Full Intake System w/ Cone Filter

   • Billet CNC turbo adapter plate attaches to stock turbo

   • Silicone intake routes to billet MAF housing

   • Stock airbox lid/filter removed

   • High-flow 6″ cone filter with velocity stack feeds cold air

   • Best choice for sound + max airflow

2. Stock Airbox Configuration

   • Billet CNC turbo adapter plate attaches to stock turbo

   • Silicone intake routes to stock MAF housing in OEM airbox

   • Removes all restrictions from turbo to airbox while retaining OEM look and sound

   • Recommended up to 700WHP for stealth builds

3. Carbon Fiber Airbox Lid w/ High-Flow Panel Filter

   • Billet CNC turbo adapter plate attaches to stock turbo

   • Silicone intake routes to MAF housing in VTT Carbon Fiber Airbox Lid

   • Uses VTT high-flow panel filter

   • Maintains stock-style appearance with increased flow and refined sound

4. Direct Compatibility with VTT “GC” Turbo Line

   • Works seamlessly with GC, GC-MID, and GC+ turbos

   • No adapter required; silicone inlet fits directly

   • For GC/GC-MID: any configuration works

   • For GC+ max-effort builds: 6″ cone recommended

Kit Contents (depending on configuration):

• 1x Billet turbo adapter with stainless hardware (optional)

• 1x Silicone inlet with dual CNC PCV adapters + clamps

• 1x Billet MAF housing with hardware (optional)

• 1x VTT Carbon Fiber Intake Housing (optional)

• 1x VTT High-Flow Panel Filter (optional)

• 1x High-Flow VTT 6″ Cone Filter with velocity stack (optional)

Applications

• Toyota A90/91 Supra with B58TU engine

• Direct fit for VTT “GC” turbocharger line

⚠️ Note on PTC Heater:
This system deletes the PTC heater. A shadow code will register in the DME, though in our testing it does not trigger a CEL. The code is only visible on scan. To fully remove it, coding is required.
