Delta Force


Take the performance of your vehicle to the next level with the addition of Flowmaster's new Delta Force Performance Air Intake system for 2009-2015 GM Sillverado/Sierra 2500HD/3500HD with the 6.0L engine. The Delta Force system contains an ultra-trick looking, custom molded black Cross-Linked Polyethylene (XLPE) high-flow intake tube, black anodized aluminum fittings, high quality reinforced silicone couplers and all stainless steel hardware for long life and a custom look. Other features include a large diameter high-flow conical shaped 8-layer cotton gauze air filter, which traps more dirt than typical 6-layer designs, a custom-fit black powder-coated air dam with attachment brackets to securely mount the system in place along with soft bumpers to eliminate any metal to metal contact under the hood. This Performance Air Intake system is a great addition to an application that has a performance exhaust and tuner.
