Overview

The Mazda Side Sill Extensions are an exterior component designed to enhance your Mazda3's appearance. These extensions accentuate the vehicle's curves while improving aerodynamics by reducing turbulence and lift.

Show original supplier description

The Mazda Side Sill Extensions, in a Glossy Brilliant Black finish, are designed to give your Mazda3 a race-inspired appearance. These extensions not only accentuate the vehicle's curves but also serve an aerodynamic purpose by reducing turbulence and lift. Specifically designed for the Mazda3 Sedan and Hatchback models from 2014, 2015, and 2016, these side sills are part of a larger Aero Kit. For a complete transformation, they can be paired with a Front Air Dam, Rear Diffuser, and Rear Lip Spoiler (for sedans) or a Rear Roof Spoiler (for hatchbacks). It is important to note that these side sill extensions cannot be installed in conjunction with Mud Guards. Ensure your vehicle is within the specified model years to guarantee compatibility.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout.
