也门采购需求：张紧轮、皮带轮、后减震器、优质减震器、滤清器、轮毂密封圈

I'm looking to procure a black air intake hose specifically designed for Nissan vehicles. Please provide me with detailed specifications, including the dimensions, material composition, and any compatible models you offer. If you have different variants available, a comparison of their features would be really helpful. Also, it would be great to know the pricing options for bulk orders, as well as your lead time for delivery. If you have any catalog or data sheet with additional products, please attach that as well. I'm eager to finalize a reliable source for this part, so prompt responses will be appreciated!
