Flowmaster Delta Force Cold Air Intake | 09-14 GM 1500 V8

Flowmaster 615120 Delta Force Performance Cold Air Intake System for 2009-2014 Chevrolet Silverado & GMC Sierra 1500 V8

Engineered to maximize airflow efficiency and deliver noticeable horsepower gains, the Flowmaster 615120 Delta Force performance cold air intake system provides an aggressive upgrade for 2009–2014 Chevy Silverado 1500 and GMC Sierra 1500 trucks powered by 4.8L, 5.3L, 6.0L, and 6.2L V8 engines. Featuring a custom-molded Cross-Linked Polyethylene (XLPE) intake tube, this high-flow assembly optimizes air velocity directly into the throttle body while minimizing heat soak under heavy loads. Powerplant engineering specialists emphasize that XLPE intake ducting significantly reduces inlet air temperatures compared to metal tubes, preserving dense oxygen charge for improved combustion and towing throttle response.

Built for extreme long-term durability in severe weather and off-road environments, the Delta Force intake utilizes a large-diameter 8-layer cotton gauze conical air filter. This multi-layer oiled design traps finer airborne particles than standard 6-layer filters while maintaining superior CFM flow rates. The system features a custom powder-coated heat shield air dam with soft perimeter bumpers to eliminate metal-to-metal contact under the hood, effectively isolating the filter from engine bay heat. Domestic shipping across North America ensures reliable delivery with zero surprise customs fees or brokerage delays.

Frequently Asked Questions

Does the Flowmaster 615120 intake require a custom computer tune?

No, the Delta Force intake system is engineered to operate seamlessly with factory ECM calibrations and retains the OEM Mass Air Flow (MAF) sensor setup without triggering a Check Engine Light.

How does the 8-layer cotton filter compare to standard air filters?

The 8-layer cotton gauze media traps significantly more dirt, dust, and fine particulate than standard 6-layer filters while maintaining high airflow rates to protect your V8 engine in harsh conditions.

Is the intake tube material resistant to engine bay heat soak?

Yes, the intake tube is molded from high-density Cross-Linked Polyethylene (XLPE), which acts as a thermal barrier to keep intake air temperatures cooler compared to traditional aluminum intake tubes.
