What the manual does not print
The 2017 Mazda Mazda3 owner's manual does not list wipers and filters sizes; for wipers, measure each blade end to end and buy the nearest whole-inch size.
Buying the parts for a 2017 Mazda3
- Headlight bulbs: the H11 low beam and the 9005 high beam are halogen capsules on trims that have them; buy them in pairs so both sides match in colour and output.
- Small bulbs: this manual names 10 replaceable bulb positions. Wedge bulbs such as W5W and 194 differ from twist-socket bulbs such as 7443 or 3157, so match the full number, including suffixes like NA (amber).
- Battery: the manual prints Q-85. Match the cold cranking amps on the old label or higher, and keep the terminals on the same sides.
Check it on your car
Trim, engine and lighting package change some of these parts, so match the row that names your engine or trim. Before you buy, compare the number printed on the old part with the table above. See how this site reads manuals.
