aFe Momentum GT Pro 5R Cold Air Intake System 19-21 GM SUV 5.3L V8

*Photo may not represent actual product

The aFe Momentum GT Pro 5R is a sealed cold air intake for the GM 5.3L V8 in Silverado, Sierra, Tahoe, Suburban, and Yukon applications, paired with an oiled Pro 5R filter. The manufacturer lists it for GM trucks and SUVs with the 5.3L V8 and states that it outflows the factory intake by 29% and gains up to +10 HP. It mounts to the factory air inlet scoop and factory mounting points, so you keep the stock intake location without adding hardware. The sealed one-piece housing is designed to draw cooler air than the stock airbox, and owners on user forums say the intake pulls air from the fender side much like the factory box. That combination is the main reason to choose it over a stock airbox for a 5.3L truck used for towing, hauling, or spirited highway driving.

Fitment is the first thing to verify. The manufacturer's listing covers GM trucks and SUVs with the 5.3L V8 from 2019 through 2026, but fitment details can differ by model year, body style, and generation, especially for 2019 to 2021 Tahoe and Suburban models. Confirm your exact year and model with the manufacturer before ordering. The kit includes the oiled Pro 5R filter and a bellows coupling, and the manufacturer's install guide for the Momentum GT platform covers a sensor transfer and clamp sequence that matters for a clean, leak-free seal. Long-tail searches for a 5.3L V8 cold air intake, a Pro 5R oiled filter, and a 2019 to 2021 GM truck intake point to this exact part number.

FAQ:

Which vehicles is the 50-70066R designed to fit?

The manufacturer lists it for GM trucks and SUVs with the 5.3L V8 from 2019 through 2026, including Silverado 1500 and Sierra 1500 models and the Tahoe, Suburban, and Yukon. Fitment can vary by model year and body style, so confirm your exact vehicle with the manufacturer before ordering.

Do I reuse my factory mass airflow sensor?

Yes. The manufacturer's install guide for the Momentum GT platform has you transfer the factory MAF sensor into the new aFe intake tube using the supplied M4 screws and the factory seal.

What comes in the box?

The manufacturer's listing includes the Pro 5R filter and a bellows coupling, along with the housing, tube, and clamps needed for installation.

Installing it yourself

Per the manufacturer's Momentum GT install guide, the job starts by disconnecting the negative battery terminal and retaining the factory parts. You will need an 8mm nut driver, an 11mm nut driver, T15 and T20 Torx bits, and a flat-blade screwdriver. Loosen the clamps at the airbox and throttle body, unplug the MAF sensor, and move it into the aFe tube with the supplied M4 screws and factory seal. Install the hump coupling and clamps on the throttle body, but leave them loose until the tube is seated, then align the tube and tighten everything. Finish by reconnecting the crankcase breather hoses between the valve cover and the tube on both sides. Owners on user forums note that the throttle-body tube can need extra attention to seat the silicone gasket, and that prying the stock sensor clip can break it on other Momentum GT applications, so work slowly on the sensor. Confirm the step list for your exact model year, since the guide the manufacturer published covers earlier Momentum GT GM applications.
