The Chevrolet Performance, GMC and Cadillac Cold Air Intake System (RPO 5W7, RVK) available on 2021 Camaro, Silverado, Tahoe, Suburban, Sierra, Yukon and Escalade models equipped with the 5.3L V8 engine (RPO L84), 6.2L V8 engine (RPO L87) or 6.2L V8 engine (RPO LT1) should only be installed on vehicles that were ordered with the RPO/LPO (dealer installed) option. (Fig. 17) The Cold Air Intake System requires a calibration from the Techline Customer Support Center (TCSC), which is not available for vehicles without the proper RPO/LPO 5W7 or RVK option.
The Cold Air Intake System is a Limited Production Option (LPO) that can be ordered with the vehicle at the time of purchase. It is not to be installed or sold as an Accessory Catalog Offering (ACO), or over-the-counter accessory, as the calibration is not available for ACO applications. If installed on an incorrect vehicle, the Check Engine MIL may illuminate and DTCs P0172 (Fuel Trim System Rich) and P0175 (Fuel Trim System Rich Bank 2) may set.
