Vehicle Specific Horn Brackets

Put the horns in the right location

A vehicle specific bracket positions aftermarket horns where they clear body panels, cooling parts and factory wiring. Confirm year and model before selecting a Subaru bracket.

Plug In Wiring Harnesses

Connect horns without guesswork

A purpose built harness uses the correct connector layout and routing for compatible vehicles. Check whether the harness is listed for the exact WRX, STI or other Subaru generation.

Relays and Circuit Protection

Support a dependable circuit

Aftermarket horns may draw more current than factory equipment. Use a suitable relay, fuse protection and wire size based on the horn manufacturer instructions.

Horn Buttons and Covers

Finish the control and appearance

Horn buttons support steering wheel applications while covers add a finished look to compatible HELLA horns. Verify button diameter and horn cover fitment.

Installation and Routing

Keep wiring protected

Route harnesses away from heat, sharp edges and moving parts. Secure the harness, confirm terminal engagement and test the horn before closing panels.

Subaru Fitment Planning
