A problem bigger than you think
Counterfeit car parts are a huge industry. By some estimates, the market for fake car parts is worth over 45 billion dollars a year globally. And we are not talking only about cheap knock-offs from shady sources. Counterfeit parts are sold in seemingly legitimate dealerships, on well-known online platforms, and even at some workshops that fit them without knowing (or caring) that they are not original.
Why does this matter? Because a counterfeit part can be dangerous. Fake brake pads that break apart on the first hard stop, a counterfeit airbag that does not deploy in a crash, a fake oil filter that filters nothing. These are not hypothetical scenarios, these are documented cases that have caused injuries and deaths.
You spot a counterfeit by the little things: packaging with poor printing, markings that look off, material that is too light. Here are the signs to watch for, how to verify authenticity, and how to protect yourself before you pay.
Which parts are most often counterfeited?
Counterfeiters focus on parts with high margins and high demand. Here are the categories most often targeted:
- Filters (oil, air, fuel, cabin) - because they are cheap to make and sell in huge volumes
- Brake pads and discs - high demand and a relatively pricey original version
- Spark plugs - small, expensive when original, easy to copy visually
- Shock absorbers - known brands like Bilstein and Monroe are frequent targets
- Belts (timing, V-belts) - critical parts with high margins
- Oils and fluids - easiest to counterfeit because the buyer cannot tell visually
- Headlights and lamps - pricey original parts, cheap to copy
- Electronic components - sensors, modules, control units
Visual signs of a counterfeit
There are a number of visual cues that can give away a counterfeit part. Here is what to look for:
Packaging
- Print quality - counterfeit packaging often has slightly blurry print, wrong colours or low-resolution graphics. Compare with original packaging (photos are on the manufacturer's website)
- Spelling errors - counterfeiters who do not speak the language of the market they sell to often make spelling mistakes on the packaging. "Brakepad" instead of "Brake Pad", "Qualety" instead of "Quality" and so on
- Barcode - scan the barcode with a phone app. If it gives no result or leads to the wrong product, that is a warning sign
- Hologram - many manufacturers use hologram stickers as protection. Check that they are there and look authentic
- Box weight - a counterfeit part is often lighter than the original because it uses less material or inferior material
The part itself
- Quality of finish - original parts have smooth, even surfaces. Counterfeits often have rough edges, uneven coatings or visible mould marks
- Markings and engravings - the OEM number, manufacturer logo and other markings should be clear, deeply stamped or precisely printed. Counterfeit parts often have shallow, wrong or unclear markings
- Colour - compare the part's colour with photos of the original. Counterfeits often have a slightly different shade
- Material - an original steel part that is unexpectedly light may not actually be steel. An original rubber seal that is stiff and brittle may not be real rubber
- Dimensions - counterfeit parts sometimes have slightly different dimensions. If a part "almost fits but not quite", it may not be original
Specific examples by category
Brake pads
Counterfeit brake pads are especially dangerous. Here is how to spot them:
- Original pads have an even friction material with no bubbles or cracks
- Counterfeit ones often have visible voids in the material
- Measure the thickness and compare with the spec. Counterfeit pads are often thinner
- Original pads carry an ECE R90 marking (European standard). Counterfeit ones often lack it or have a fake one
- Check the backing plate. The original is flat and precisely cut. A counterfeit can have uneven edges
Oil filters
Counterfeit oil filters are common because they are cheap to make. The differences:
- The original has a quality rubber gasket that is flexible and uniform
- A counterfeit has a stiff, warped or thin gasket
- Open up (cut open) an old filter and compare the filter media. The original is densely pleated and uniform
- A counterfeit often has fewer folds or thinner paper
- The bypass valve in an original filter is calibrated to the exact pressure. A counterfeit sometimes lacks one entirely
Timing belts
A counterfeit timing belt that snaps means a destroyed engine (in interference engines). What to watch for:
- An original belt has clear, sharp teeth with even spacing
- A counterfeit has rounded teeth or uneven spacing
- Check flexibility. The original bends smoothly, a counterfeit can be too stiff or too soft
- Markings on the belt should be clear and precise
How to protect yourself when buying
Here are practical steps to reduce the risk of buying a counterfeit part:
1. Buy from trusted sources
Authorised distributors, known dealerships and platforms with vetted suppliers are safer than unknown online sellers. On the PoDi platform, we connect you with suppliers of used parts who guarantee authenticity.
2. Compare prices
If the price is too good to be true, it probably is. An original Bosch starter cannot cost 15 EUR when its used market price is 50 to 80 EUR. A price that is 50% or more below market is a warning sign.
3. Check the OEM number
Type the OEM number from the part into a cross-reference database and check that it matches. Counterfeiters sometimes use a wrong OEM number or one that does not exist.
4. Ask for certificates
Original parts come with quality certificates (ECE, ISO, TUV markings). Check that they are present and look authentic.
5. Use verification apps
Some manufacturers (e.g. Bosch, Mann, SKF) have apps or websites for authenticity checks. You scan a barcode or enter a serial number and get confirmation whether the part is original.
6. Physically inspect the part
If you buy in person (not online), always inspect the part before buying. Check all the visual signs we described above.
Used vs counterfeit: a key difference
There is a big difference between a used original part and a counterfeit new part. A used original part was made by the original manufacturer, was fitted to a car and used, but is still of original quality. It may have signs of use, but the material, design and workmanship are original.
A counterfeit "new" part was made by an unknown factory that copies the look of the original but uses inferior materials and processes. It may look new and shiny, but the quality is far below standard.
Ironically, a used original part is often a better and safer choice than a new counterfeit. That is why buying used original parts on platforms like PoDi can be a smarter choice than buying suspiciously cheap "new" parts from unknown websites.
What to do if you bought a counterfeit?
If you suspect you bought a counterfeit part:
- Do not fit it - especially if it is a safety part (brakes, belt, airbag)
- Contact the seller - ask for a refund and explain the situation
- Report it - if you bought online, report the seller to the platform. If you bought in a shop, contact the inspectorate
- Document it - photograph the part and packaging, keep the receipt
- Notify the manufacturer - original manufacturers want to know about counterfeits on the market and can help with identification
How platforms like PoDi help
On the PoDi platform, we work to reduce the risk of counterfeit parts. Suppliers are vetted, parts come with clear markings of origin and condition, and the review system helps identify reliable sellers.
When you buy a used original part, the risk of a counterfeit is significantly lower than when buying a "new" part from an unknown manufacturer. A used part with a visible OEM number, signs of fitting and known provenance (which car it was removed from) is almost certainly original.
Skepticism toward too-good prices
Counterfeit car parts are a real problem that can affect your safety and the safety of your family. But with a little knowledge and attention, you can significantly reduce the risk. Check OEM numbers, buy from trusted sources, be skeptical of prices that are too good to be true, and always physically inspect the part when possible.
And remember: a quality used original part is almost always a better choice than a suspicious new part of unknown origin. When you need a part, send a request on PoDi and be confident that you are getting an original part at a fair price. Your safety deserves it.
