Flowmaster 615212 Details


Take the performance of your vehicle to the next level with the addition of Flowmaster's Delta Force Performance Air Intake system for 2019-2022 RAM 2500/3500 trucks with the 6.4-liter engine. Dyno gains of 13 hp and 17 lb-ft over stock at the rear wheels. 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.
