WHERE TO BUY

Open an exact listing, then confirm fitment, stock, price, and shipping with the seller before ordering.

Seller links checked . Prices and availability can change.

What you need to know

First identify NA, NB1 or non-turbo NB2 and confirm VIN, front-only location and installed numbers. A cover is not a complete bumper assembly: reinforcement, center retainer, guards/slides/seals, air guides, lamps, emblem, plate hardware, fog-lamp trim and finish may be separate. Current US seller catalogs sometimes consolidate NC10-50-071A through 2005 while Mazda legacy evidence lists N066-50-071 for later NB; do not infer interchange. Shared side-marker housings do not prove a shared bulb specification.

Fitment

First identify NA, NB1 or non-turbo NB2 and confirm VIN, front-only location and installed numbers. A cover is not a complete bumper assembly: reinforcement, center retainer, guards/slides/seals, air guides, lamps, emblem, plate hardware, fog-lamp trim and finish may be separate. Current US seller catalogs sometimes consolidate NC10-50-071A through 2005 while Mazda legacy evidence lists N066-50-071 for later NB; do not infer interchange. Shared side-marker housings do not prove a shared bulb specification.

Aftermarket options

The checked evidence supports generation-correct replacement covers and separate OEM reinforcement/retainer/marker components. Aftermarket covers still require generation, turbo status, lamp/fog openings, material, finish and shipment-condition checks. Universal body kits, generation conversions and the Mazdaspeed cover are not represented as non-turbo direct replacements.

Before you buy

This guide covers US 1990-1997 NA, 1999-2000 NB1 and 2001-2005 non-turbo NB2 front parts only. A cover is not a complete bumper assembly. Verify VIN, generation, turbo status, installed reinforcement/retainer numbers, marker side, finish and listing contents. Do not infer NB1/NB2 reinforcement interchange from broad seller fitment, and do not assume a shared marker bulb from shared housings. Mazdaspeed, rear, non-US, body-kit and generation-conversion paths are excluded. Seller states and freight are dated observations.
