Thousands of tiny shops in India's biggest auto components market do brisk business selling a bewildering array of spare parts for about a third of the official price charged by the likes of Toyota Motor or Volkswagen.
Generic parts sold by traders in places like old Delhi's Kashmere Gate market account for about a sixth of India's $6.6 billion after-sales components sector, IHS Automotive estimates, but a recent move by regulators could boost that share.
Just as India has become a global hub for the manufacture of cheaper copycat medicines, the Competition Commission's ruling last month requiring car makers to supply parts more widely could encourage the production and sale of non-certified generic components in the world's sixth largest auto market.
"We have the ability to make good quality products, we have our techniques and this is our chance to prove it," said trader Umesh Seth, sitting in a poky store where hundreds of sheet metal parts wrapped in transparent plastic are piled on racks. "It is about time we get an equal opportunity."
The Competition Commission's ruling has irked auto majors, who argue that a proliferation of cheap copycat components will undermine the safety and reputation of their brands.
In developed markets such as Europe or North America, sundry spares like oil filters, spark plugs or shock absorbers are available from a variety of suppliers, keeping competition keen.
But in markets such as China and India, global car makers have maintained tighter control over the supply and price of spares, selling them through a limited network of vendors.
While car makers and their authorized dealers cite safety as the main reason, this practice has also allowed them to protect hefty margins on parts and repairs, while inflating the cost of car ownership for consumers.
Regulators are now ending all that and the crackdown in India follows a wider, ongoing probe in China where some part makers are being investigated for colluding to keep prices high.
"I would like it if there is competition for the car companies," said Nirav Savla, a 29-year-old businessman from Mumbai who drives a Toyota Innova. "For small parts, I do not need to go to them."
In the Kashmere Gate market, a maze of lanes and alleyways lined with men loading handcarts with spares tightly packed in sacks, a generic set of headlights for Hyundai Motor's Santro hatchback costs 1,500 rupees ($24.65), less than half the price of the manufacturers' original.
"There are all kinds of customers and we have something for every pocket," said a maker of generic bearings used in commercial vehicles. "They are smart enough to know which local parts are good quality and which ones are not."
