A silicone replacement for the factory plastic pipe that carries cooled air from the intercooler to the engine on the 3.0L diesel. It is a durability and airflow upgrade, not a big power part by itself.
why this one — S&B is a well-known diesel filtration and piping brand, and this part is made specifically for the Sierra 1500's diesel engine with a direct SKU match, not a universal clamp-on hose.
S&B's own product page only claims "less restriction for improved airflow" versus the stock plastic pipe; no HP/TQ figure is published for this part.
No published gain figure for this part, and nothing here is a guarantee. Price is a list price and can lag the retailer; confirm at checkout. See how we check a price and our affiliate disclosure.
