An original part is sold under the car maker's brand. An aftermarket part is sold under another manufacturer's brand. Compare the specific parts, not just the box label.
Two offers, the same checks
1
Original: car-maker brand + number
2
Aftermarket: part brand + article

Both: fitment, contents, terms
What to do, step by step
Ask for the brand and number
Ask who made the part and what its number is. Unknown origin needs clarification. 'Like original' is not a manufacturer name.
Compare the contents
A lamp may come with or without modules; a bumper may exclude grille and fixings. Compare equivalent contents with verified fitment.
Check terms before payment
Confirm price, warranty and returns for this item. Price alone proves neither quality nor authenticity.
More detail and common mistakes
- Confirm the manufacturer and exact article. A cross-reference links catalogue entries but does not prove that every version is interchangeable.
- Use verified information to compare material, fixings and contents. Lighting requires matching technology, electronics and connectors; filters require matching engine and dimensions.
- Ask about warranty and return terms for the specific item before payment. KRONIS labels origin only when known; an absent label means it needs checking.
