Abstract: The present invention provides an admission pipe structure for automobile air admission, wherein internal part in pipe body of admission pipe includes channel, admission hole and exit hole formed on two sides of the channel are installed with first sleeve connection part and second sleeve connection part, and first sleeve connection part and second sleeve connection part are respectively sleeved onto exit connector and admission connector of the admission manifold pipe such that buckling component can be set up in penetration into two through-grooves installed in outer surface of second sleeve connection part thereby using buckling component to block at ring-shaped groove for fixedly positioning. When compressed air coming from the central cooler enters into admission pipe, compressed air can be smoothly guided by arc-shaped channel in pipe body, and aluminum alloy materials in admission pipe itself can prevent damages caused by the high-speed airflow of the compressed air.
