Smeding Diesel 20-24 Duramax L5P High Flow Bundle Kit   Designed for the 2020–2025 L5P Duramax, this performance package improves both intake and exhaust flow by combining a high-efficiency airflow system with a 3.5-inch downpipe upgrade. It helps your turbo and engine breathe better, delivering sharper throttle response, quicker turbo spool, and overall better performance. This setup also replaces factory components known to restrict flow or fail under pressure, reducing the risk of boost leaks, power loss, and reliability issues in heavy-duty or high-performance use. 4" Aluminum intake 4" Intake horn a PCV port & surge ring Air box with dry filter Complete installation kit: includes 4" silicone hump boot and stainless steel T-bolt clamps 3" Hot side intercooler piping 3.5" Cold side intercooler piping CNC machined flange and billet aluminum adapter with dual o-rings OEM clip at Y-bridge connection replaced by silicone boot and t-bolt clamps for superior sealing
