Frequently asked questions about car parts
Where to buy car parts cheap online?
RockAuto.com — deepest catalog + lowest prices (often 30-60% off retail). Save by ordering from one warehouse (free shipping over $25). Amazon Automotive for consumables. AutoZone/O'Reilly online for parts pickup. Used: LKQ.com, Pull-A-Part, local salvage yards. Avoid no-name Amazon brands for brakes, suspension, safety-critical.
OEM vs aftermarket parts?
OEM (original equipment manufacturer): exact match to factory part, longest warranty, highest quality, most expensive. Aftermarket: third-party manufacturers, lower cost (40-60% less), quality varies. Use OEM for safety-critical (brakes, airbags) + electronics. Aftermarket fine for consumables (filters, wipers, body trim).
What brand of car parts are best?
Brake pads + rotors: Bosch, Akebono, PowerStop. Spark plugs: NGK Iridium, Denso Iridium. Oil filters: WIX, OEM, Bosch. Batteries: Optima (AGM), Interstate, Costco Kirkland. Tires: Michelin, Continental, Bridgestone. Belts + hoses: Gates, Continental. Avoid Bosch's lower-tier 'Quietcast' line — go with their premium 'BC' line for brakes.
Should I buy used or new auto parts?
Used for: engine components from low-mileage salvage cars (LKQ, Car-Part.com), bumpers + body panels, glass, wheels. New for: brakes, belts, hoses, filters, electrical, anything safety-related. Junkyard parts cost 20-40% of new with research time investment.
How do I find the right parts for my car?
RockAuto's catalog filters by year/make/model/engine — match exactly. Cross-reference part numbers from your owner's manual or dealer service. Forum boards for your specific car (camrycustoms, ToyotaNation, etc.) have parts compatibility info. Always double-check before ordering — wrong-fit parts are expensive to return.

Brake pads: 30,000-70,000 miles. Brake rotors: 70,000-100,000 miles. Tires: 50,000-70,000 miles. Belts: 50,000-100,000 miles. Battery: 4-7 years. Alternator: 80,000-150,000 miles.
