Product Details

Product Name: HSP S300 Hotside Tube - LB7-LMM Duramax - 01-10 Duramax
Manufacturer: HSP Diesel
Manufacturer Part #: 021-HSP-X
Thoroughbred Diesel Part #: HSP021-HSP-X
Fitment Notes: 01-10 Duramax

This S300 based hot side intercooler tube is only applicable for aftermarket S300 turbo options. Specifically, with a 6.5" turbo pedestal in the valley. With additional boost from your upgraded turbo, the lower factory intercooler boot will be prone to leak or burst. By design, the lower connection to the HSP intercooler tube eliminates the drastic 90-degree boot. Our hot side is constructed from 3" mandrel bent tubing for smooth, sweeping bends, and proper fitment. Don't be left stranded with weak, non-reinforced silicone boots. Trust in your setup with the strongest HSP components to withstand the demand of your turbo.

Based on Borg Warner s300, and Garrett mid frame turbo's with 6.5'' pedestal
