How to treat the brands and manufacturers of throttle valves?

The quality is different from the price.

The accessories of the general factory are generally the second-class accessories suppliers designated by the general factory. In order to distinguish these accessories from those of auxiliary factories, there is usually a logo of the main factory or the supplier of the main factory. Normal factory fittings are of good natural quality. Generally speaking, there is nothing wrong with the appearance and performance, but the corresponding price is also relatively high. Accessory factory accessories are factory accessories of large and small brands, with different prices and naturally uneven quality. The manufacturer of sub-factory parts may have been the supplier of the main engine factory, but later it was eliminated by the main engine factory, or there may be three brands, and the quality is completely guaranteed.

The throttle valve is located behind the air cleaner element of the intake system and in front of the intake manifold. Throttle is the throat of the engine, which can control the intake of the engine.
