DHD's LML Turbo Saver is designed to work with factory airbox LML Duramax trucks from 2011 to 2016.
We have seen a trend with the LML trucks where extended service intervals on air filters have actually caused the inner filter support to collapse under high vacuum. Once the OE plastic support collapses all bets are off. By the time the end user identifies the issue its typically to late. Both the plastic from the support and air filter byproducts ruin the compressor wheel of the turbo.
This billet aluminum support replaces the failure prone plastic support and will minimize the risk of air filter ingestion in the event the filter is restricted or during high vacuum, high boost events.
