Electronic Throttle Body 16112-AA550 Subaru BRZ Toyota GR86 AKAS

The AKAS Electronic Throttle Body is a precision drive-by-wire throttle valve assembly replacement for Subaru/Toyota vehicles equipped with FA24 2.4L Naturally Aspirated Boxer 4-Cylinder Petrol engines (2022-2025), replacing Subaru OE 16112-AA550.

PETROL ONLY - Exclusive for Subaru/Toyota FA24 2.4L Naturally Aspirated Boxer 4-Cylinder Petrol engines. This electronic throttle body controls the amount of air entering the engine based on accelerator pedal position and ECU commands, featuring an integrated throttle position sensor (TPS) and DC motor for precise, linear throttle response. Direct-fit installation with identical mounting points and electrical connector to the original factory part - no modification, adapter, or machining required. High-strength aluminium alloy housing with anti-foul coated valve plate and FKM fluoroelastomer seals ensures long service life. Backed by a 6-month limited warranty.

1. Electronic Throttle Body - Precise Drive-by-Wire Control This is an electronic throttle body (drive-by-wire) with integrated throttle position sensor (TPS) and DC motor, precisely controlling air intake for Subaru/Toyota FA24 2.4L Naturally Aspirated Boxer 4-Cylinder Petrol engines based on accelerator pedal position and ECU commands for linear, smooth throttle response with zero lag or hesitation. Resolves common faults including rough idling, fluctuating idle speeds, hard starts, reduced power, and unexpected stalling - clearing P0120/P0121/P0122/P0123/P0220/P0221/P0222/P0223/P2119 throttle position sensor fault codes. Replaces Subaru OE 16112-AA550.

2. Exact OE Match - FA24 2.4L Boxer Only Precision direct-fit electronic throttle body for Subaru BRZ ZD8 (2022-2025) 2.4L FA24, Toyota GR86 ZN8 (2022-2025) 2.4L FA24 with Subaru/Toyota FA24 2.4L Naturally Aspirated Boxer 4-Cylinder Petrol engines. 1:1 OE dimensions, OE connector, identical mounting points - no modification required. PETROL ONLY - not compatible with 2.0L (FA20), turbocharged (FA24DIT), diesel, or other engine variants. Verify original OE number before purchase.

3. Direct-Fit Installation - Save Time & Labour Identical form, fitment, and dimensions to the original factory Subaru/Toyota throttle body - no grinding, modification, or machining required. Installs directly onto your intake manifold with ease, using existing mounting bolts and electrical connector. Pre-calibrated at the factory to OE specifications - however, an OBD scan tool may be required to clear fault codes or perform throttle adaptation (OBD relearn / idle air volume learning) after installation on certain vehicle models with factory ECU programming protections.

4. Premium Materials & Precision Engineering - Built to Last High-strength aluminium alloy housing with excellent corrosion and heat resistance prevents warping and air leaks even under sustained high-temperature operation. The valve plate features a durable non-stick anti-foul coating that repels carbon deposits and oil residue, significantly reducing the need for frequent cleaning. Fitted with high-temperature fluoroelastomer (FKM) gaskets that resist oil vapour degradation, preventing ageing, oil seepage, and air leaks over extended use. Meticulously calibrated valve clearances eliminate issues such as incomplete closure, binding during operation, and sluggish return.

5. OE Quality at Aftermarket Value - 6-Month Warranty Manufactured to strict Subaru/Toyota OE specifications with dependable electronic precision, rapid signal feedback, solid high-heat tolerance, and anti-vibration capability - performing comparably to the genuine Subaru/Toyota throttle body (16112-AA550) at a fraction of Subaru/Toyota main dealer cost. Backed by a 6-month limited warranty covering manufacturing defects. For South African Subaru/Toyota owners - where BRZ and GR86 remain popular sports cars and FA24 2.4L electronic throttle body failure is a common cause of rough idling, reduced power, and failed emissions/roadworthy tests.

PETROL ONLY - VERIFY COMPATIBILITY: This electronic throttle body fits Subaru BRZ/Toyota GR86 with FA24 2.4L Naturally Aspirated Boxer 4-Cylinder Petrol engines (2022-2025), replacing Subaru OE 16112-AA550. PETROL ONLY - Exclusive for Subaru/Toyota FA24 2.4L Naturally Aspirated Boxer 4-Cylinder Petrol engines. NOT compatible with 2.0L (FA20) / Turbocharged (FA24DIT) / Diesel, NOT for other engine variants. Verify original OE number, engine code, and fuel system before purchase.

VERIFY OE NUMBER: Before making the purchase, please make sure that the OE number is correct. If the OE numbers do not match, they cannot be used together. This throttle body replaces Subaru OE 16112-AA550. Do NOT substitute with a different OE number throttle body (e.g. 16112-AA380 for BRZ/86 2.0 FA20, 16119-EN20C for X-Trail 2.0 MR20DE) - they have different calibrations, connector types, and bore diameters and are NOT interchangeable.

OBD ADAPTATION / IDLE AIR VOLUME LEARNING MAY BE REQUIRED: Due to factory ECU programming protections on certain Subaru/Toyota vehicle models, an OBD scan tool may be required to clear fault codes or perform throttle adaptation (OBD relearn / idle air volume learning) after installation to ensure proper operation. This is a function of the vehicle's original software, not a product defect. Please confirm whether your vehicle requires OBD adaptation before placing your order. If OBD adaptation is required, an OBD tool must be purchased separately.

PROFESSIONAL INSTALLATION: Recommended for proper torque on mounting bolts, correct intake manifold gasket seating, and clearing of diagnostic trouble codes (DTCs) / throttle adaptation after replacement. Allow engine to cool completely before servicing. Ensure the intake manifold mating surface is clean and free of old gasket material, carbon deposits, and oil residue before installation. Do not over-tighten mounting bolts.

WARRANTY: 6-month limited warranty covering manufacturing defects under normal use. Does not cover improper installation, drops, contamination, water ingress, use on incompatible vehicles/engines (2.0L/Turbo/Diesel/other variants), wrong OE number, modification, or normal wear. This is an aftermarket replacement part - not affiliated with or manufactured by Subaru/Toyota.
