Perrin [15-21 WRX/STI, 13-17 Crosstrek/Impreza] Hella Horn Bracket Suspension Tuning RHD vehicles require an ETD

RHD vehicles require an ETD (Engine Torque Damper) for proper fitment

Designed specifically for custom forward-facing intake manifold (FFIM) setups on 2JZ-GE engines

this sensor allows for seamless integration into Subaru FA20 platforms while enabling safe and accurate ECU calibration for high-boost applications

High-velocity airflow optimization

Perrin [15-21 WRX/STI, 13-17 Crosstrek/Impreza] Hella Horn Bracket Suspension Tuning RHD vehicles require an ETDThe PERRIN Brackets for HELLA Horns are designed with vehicle specific fitments to ensure the strongest and best fitting bracket possible. The reason Perrin's parts aren't universal is because, during the prototype phase, they found that making a part that fit every vehicle compromised strength and rigidity. The PERRIN Brackets come with slotted mounting points for horn assemblies. These allow for fine tuning of the position of horns to work with
