Yes, they are OEM parts. Parts can be classified as follows: 1. OEM parts: As the name suggests, OEM parts are those with the car manufacturer's logo, representing the most "genuine" parts, meeting the same quality standards as the original components in the vehicle. Typically, they are supplied to authorized 4S stores, though some may also be available at certified partners, and they are usually the most expensive. 2. Original equipment (OE) parts: Many car parts are not manufactured by the automaker but are outsourced to experienced suppliers like Bosch, MAN, Valeo, Hella, etc. These suppliers are permitted to produce parts of the same specifications for their own sales, but without the car manufacturer's logo. Generally, OE parts are slightly cheaper than OEM parts. 3. Aftermarket parts: Aftermarket parts come from various sources. The first type is produced by small and medium-sized suppliers with production qualifications, using materials and processes similar to OEM parts but not approved by the automaker. The second type involves parts imitating certain car models' specifications, with varying materials and processes but sold under their own brands. The third type consists of counterfeit OEM or OE parts. Due to their diverse origins, aftermarket parts vary greatly in price. High-quality aftermarket parts may cost half the price of OEM parts, while lower-quality ones may be a quarter or even less.

I've been driving for years and have done a lot of repairs myself. Genuine parts and OEM parts are basically the same, both made to original factory standards. OEM parts come directly from the car manufacturer, while genuine parts are produced by authorized suppliers according to OEM specifications, such as those made by big brands like Bosch. Their quality, dimensions, and materials strictly comply with the standards, so they work just fine for repairs. I've replaced several parts like wiper blades or air filters—genuine parts are a bit cheaper but perform just as well, and they fit perfectly when installed. The key is to look for certification marks and avoid buying from roadside stalls, where you might encounter counterfeit parts that compromise safety. Genuine parts have good compatibility, don’t void the warranty, and save money while ensuring peace of mind, making them ideal for DIYers like me. When selecting parts, check the OEM number to match the original and buy from reputable stores.

Last time I went to the 4S shop to replace brake pads, the technician told me that genuine parts are just another name for OEM parts, with no essential difference. OEM parts strictly come from the car manufacturer, while genuine parts might be outsourced to major companies, but they adhere to the same testing standards and are safe and reliable to use. I replaced my air filter with a genuine one, costing only half the price of an OEM part, and it's been working perfectly for over a year. During maintenance, the technician emphasized checking the anti-counterfeit code on the packaging and avoiding cheap deals to prevent buying substandard products. Genuine parts are common in the aftermarket, easy to match, and for small components like headlights or wipers, DIY replacement is convenient. Always ask for recommendations from repair shops, look for authorized stores, and don't easily trust cheap online deals. Protecting your beloved car starts with the details, and genuine parts are a cost-effective choice.

What Causes the Clunking Sound from the Front Wheels When Going Over Speed Bumps?

The clunking sound from the front wheels when going over speed bumps is caused by a loose stabilizer bar or faulty shock absorbers. When a car goes over a speed bump, it involves the compression movement of the wheels (including the suspension) between the ground and the car body. Noise from the shock absorbers themselves is rare and usually only occurs when they are malfunctioning. It is recommended that owners promptly inspect and repair the vehicle when such noises appear. Shock absorbers can be categorized based on the damping material used, mainly into hydraulic and pneumatic types, with another type being variable-damping shock absorbers. The primary function of shock absorbers is to suppress the oscillations from the rebound of springs after absorbing shocks and the impacts from the road surface. When driving on uneven roads, although the shock-absorbing springs can filter out road vibrations, the springs themselves still undergo reciprocating motion, and the shock absorbers are designed to control this spring bounce.

What Causes the Rattling Sound in the Steering Wheel When Driving on Rough Roads?

The rattling sound in the steering wheel when driving on rough roads can be caused by several reasons: friction between the steering column and floor mats, malfunction of the clock spring (spiral cable), lack of lubrication in the shock absorber's thrust bearing, loose stabilizer bar bushings, dirty power steering fluid, or noise from the turn signal return clip. Additionally, faults in the shock absorbers or stabilizer bar links may also be the culprit. It is recommended to visit a 4S store or professional repair shop for inspection and maintenance. The steering wheel is a wheel-shaped device used in cars, ships, and airplanes to control the direction of travel. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque, which is then transmitted to the steering shaft. It mainly consists of a skeleton, foam padding, and the driver's airbag.

What Do Horsepower, Torque, and Power Represent?

Horsepower is a commonly used unit of power measurement in engineering. Torque is the force that causes an object to rotate. Power refers to the amount of work done by an object per unit of time, meaning power is a physical quantity that describes how fast work is done. The relationship between horsepower, torque, and power: Horsepower and power can be converted into each other. Both horsepower and power indicate how much work an engine can perform per unit of time. An engine with higher power has stronger performance but also higher fuel consumption. Power is an important performance parameter of an engine. Torque refers to the moment that the engine crankshaft can output, which is the force that makes the crankshaft rotate, hence also called torque. An engine with higher torque also has higher power. Power is directly proportional to both speed and torque. An engine with higher speed also has higher power because it performs more work cycles per unit of time. Horsepower, torque, and power each determine a specific factor of a vehicle: Power determines the maximum speed a vehicle can achieve; torque determines how quickly a vehicle can accelerate. However, when torque alone cannot increase speed, power is needed to enhance it. Therefore, power and torque complement each other.

What are the new regulations for private cars after 15 years?

The new regulation for vehicles over 15 years old is that the inspection cycle is every six months. For vehicles over 10 years: For private cars over 10 years old, the original inspection cycle is still followed, i.e., 10-15 years, inspected once a year; over 15 years, inspected every six months. On the basis of exempting non-operational small and mini passenger vehicles with 6 seats or less from inspection within 6 years, the exemption now also includes non-operational small and mini passenger vehicles with 7 to 9 seats (excluding minivans) within 6 years. Under 10 years: For non-operational small and mini passenger vehicles (excluding minivans) over 6 years but under 10 years, the inspection frequency is adjusted from once a year to once every two years. If a vehicle is involved in a fatal traffic accident or is illegally modified and penalized according to law, it will still follow the original inspection cycle to ensure the vehicle's safety performance. Inspection content includes: whether the vehicle has a user manual, certificate of conformity (inspection certificate for imported vehicles), and whether the factory inspection marks on the vehicle body are complete; measuring the external and internal dimensions, wheelbase, and axle track of the vehicle. Specific measurement items include vehicle length, width, height, cargo compartment height and area, wheelbase, axle track, etc.; each item is checked according to technical inspection standards. Upon passing the inspection, fill out the "Initial Inspection and Alteration Registration Form for Motor Vehicles" and record the curb weight, load capacity, passenger capacity, and driver's cabin seating capacity as specified by the manufacturer. For non-operational passenger cars, the previous mandatory scrapping age was 15 years, but this did not align well with the actual usage of motor vehicles in China. Therefore, China issued new private car scrapping regulations, eliminating the mandatory scrapping age and replacing it with a guideline for scrapping when the mileage reaches 600,000 kilometers.
