I'm reaching out to gather more details about vehicle air intake rubber hoses. Specifically, I'm interested in the different specifications, material options, and any available sizes you offer. It's crucial for me to understand the performance characteristics and durability of these hoses, as they play a vital role in vehicle efficiency. Additionally, could you provide information on your lead times and bulk pricing options? If there are any certifications or standards these products meet, that would be useful too. Looking forward to your prompt response so we can potentially move forward with an order. Thanks!
