QI has developed 22 models of dual-mass flywheels, covering Audi, VW, Peugeot, Ford, Cadillac, etc., with a total mold investment of over US$600,000. Each dual-mass flywheel has been verified by 100,000 kilometers of simulation durability tests. The products comply with OE standards and have reliable quality.

QI blind spot detection sensor has professional algorithm simulation capabilities and covers a large amount of special and regular working condition test data. It also has 77G millimeter-wave radar system, which basically covers all the functions of the blind spot system of mass-produced models on the market. QI has a professional development team that can customize product functions according to customer needs. Currently, 12 blind spot detection sensors have been developed.

In response to the problem of differential noise and oil leakage that often occurs in rear-wheel drive vehicles, four-wheel drive vehicles, and hard-core off-road vehicles, QI has developed conventional differentials and locking differentials for Cadillac series, BMW series, Jeep series, etc. based on market research results. Products such as transmissions and limited-slip differentials have been widely praised by the market.

The function of the DPF additive tank is to store and add catalyst to the fuel tank. Currently QI has developed 17 models of DPF additive tanks. The product is cost-effective and its performance meets OE standards. Each product is tested in Europe for more than 10,000 kilometers to ensure quality and durability.
