Functional Black Shark Fin Antenna for Mazda 3 (2004-2018) - Modern

Our review of the Functional Black Shark Fin Antenna for Mazda 3 (2004-2018) finds it best for owners who want a simple, cosmetic upgrade that also retains AM/FM reception. The bottom line: this is a straightforward replacement for the factory mast that covers the existing antenna base and provides a cleaner, more modern roofline. It arrives as a brand new, paintable shark fin with the required screw and 3M adhesive tape, so installation is primarily a matter of mounting it over the vehicle's current antenna base without altering factory radio or navigation systems.

Key Features

• Direct fit: Designed to fit Mazda 3 models from 2004 to 2018, so buyers can expect a compatible replacement for that full model range.
• Functional AM/FM reception: Replaces the existing mast while maintaining AM/FM antenna function for continued radio use.
• Included hardware: Comes with the needed screw to connect the antenna wire to the base so no extra parts are normally required.
• 3M adhesive tape: Supplied tape helps create a secure seal when mounting the fin over the existing antenna base, reducing the chance of uplift or gaps.
• Paintable material: The fin is made of paintable material so owners can color match it to their vehicle for a factory look.

Who It's For

This shark fin is aimed at Mazda 3 owners from 2004 through 2018 who want a cosmetic update and the cleaner appearance of a factory-style fin without affecting AM/FM radio. It is also suited to DIY enthusiasts comfortable with modest exterior work and using supplied 3M tape and a small screw to secure the part.

Those who rely on Bluetooth, Sirius XM, or GPS navigation need not worry, as those services use separate antennas and are not affected. Buyers seeking an active replacement that adds GPS or satellite functionality should look elsewhere, since this unit only replaces the AM/FM mast and covers the antenna base.
