Part #: 615121
Take the performance of your vehicle to the next level with the addition of Flowmaster's new Delta Force Performance Air Intake system for 2014-2016 Chevrolet Silverado 1500 and GM Sierra 1500 Trucks with 5.3L 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 (when applicable), high quality reinforced silicone couplers and all stainless steel hardware. 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. The Delta Force Air Filters are serviceable with our new Delta Force cleaning kits which will help outlast your vehicle. For maximum performance and that iconic Flowmaster exhaust tone, we highly recommend pairing your new Delta Force Performance Air Intake with a Flowmaster exhaust system.
