I'm looking for a charge air cooler replacement. Note that this unit needs to be compatible with previous models. The new part must fit the specified requirements and work seamlessly with the older versions. Please confirm the availability and lead time for this part. Additionally, I'd appreciate a quote including any bulk order discounts and shipping details. Looking forward to your prompt response. Thanks!
