Auto Care Tips &
Expert Advice

If you've ever gone to a local auto parts market in Ahmedabad and been confused by all the options — original, duplicate, company parts, local parts — you're not alone. Understanding the difference between OEM, OES, and aftermarket parts can save you thousands of rupees and prevent serious vehicle damage.

What Are OEM Parts? (Original Equipment Manufacturer)

OEM parts are made by the same manufacturer that produced the original part for your vehicle. For example, if your Maruti Suzuki Swift needs a new brake pad, the OEM part would be the exact same brake pad that came fitted from the factory — made by the same supplier Maruti uses.

Pros: Perfect fit, guaranteed quality, maintains resale value
Cons: Slightly more expensive, only available through authorized channels
Best for: Critical components like brakes, engine parts, suspension

What Are OES Parts? (Original Equipment Supplier)

OES parts are made by the same supplier that makes parts for the car manufacturer — but sold separately under the supplier's own brand name. For example, Bosch makes fuel injectors for many car brands and also sells the same parts under the Bosch brand in the market. OES parts are equally reliable as OEM but often more affordable.

Pros: Same quality as OEM, more affordable, widely available
Cons: Slightly different packaging/branding from factory
Best for: Filters, belts, spark plugs, batteries, and most maintenance parts

What Are Aftermarket Parts?

Aftermarket parts are made by third-party manufacturers who had no involvement in making the original vehicle. Quality varies massively — some reputed aftermarket brands make excellent parts, while cheap "local market" parts from Ahmedabad's auto bazaars can be dangerously substandard.

Pros: Very affordable
Cons: Highly variable quality, may void warranty, potential safety risk
Best for: Non-critical accessories only — never for safety-critical components

How to Avoid Fake Parts in Ahmedabad's Auto Market

• Always ask for a printed bill with HSN code and GST number
• Check for the manufacturer's hologram or QR code on the packaging
• Verify the part number matches your vehicle's manual or the manufacturer's website
• Be suspicious of prices that are dramatically lower than market rate
• Buy critical parts only from authorized dealers or trusted platforms like Mechanistar

The Mechanistar Difference

When you order auto parts through Mechanistar, you get OEM or OES certified parts every time — with a valid bill, manufacturer warranty, and the guarantee that what you ordered is what you get. No confusion, no compromise, no fake parts.
