GM Accessory Cold Air Intake System Requires Calibration

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.


Calibrations for GM Accessories

GM Accessories that require updated calibrations must have the calibrations installed to ensure proper operation of the new accessory components as well as other related vehicle systems, whether it’s an air intake system that includes an ECM update, a front grill package that involves front camera operation, or larger wheels and tires that impact the operation of Advanced Driver Assistance Systems on the vehicle. Calibration updates that are not performed following the installation of an accessory may not only limit system performance, but may also leave the vehicle non-compliant with regional government regulations.

TIP: If programming is attempted before contacting TCSC when installing accessories that require an updated calibration, the Service Programming System (SPS) will not deliver the correct accessory calibration to the vehicle. SPS may display a message advising users that they are attempting to program with the “same calibration” — a warning that the vehicle has not received the required accessory calibration.


Installation Information

Installation sheets for GM Accessories can be found in the Accessories Manuals in the Service Information. If the procedures are updated or improvements are made, checking the instructions with each installation will ensure the latest information is being followed.

To locate the instructions, select the year, make and model of the vehicle from the dropdown menus. Next, from the Publication page, select the Accessories Manual link. (Fig 18)
