I'm looking for a charge air cooler that corresponds with a specific replacement model. The old parts I'm referencing have a few different numbers associated with them, and I need confirmation on the new part's compatibility with these previous models. Could you provide details on the availability, pricing, and any lead times for the cooler? Additionally, if there are any updates or improvements in the new model compared to the old ones, please let me know. This info would be really helpful for us in making a quick decision.
