Decent, but it's tough on the environment.

TL;DR Disposable pleated-paper filter: the genuine GM factory OE part (84121219) for the 2020-present Silverado and Sierra 1500 3.0L Duramax diesel, dropping into the factory K47 high-capacity air box. Fitment is confirmed across two independent parts databases plus the GM catalog and a mainstream owner base, but it is the diesel element, so gas 5.3L and 6.2L V8 trucks need a different filter.
The A3244C is a disposable pleated-cellulose engine air filter classified by ACDelco as "GM factory OE," the same part GM installs at the factory and supplies through dealerships as GM 84121219. Construction is standard OEM: resin-treated paper media over a metal mesh backing with a molded urethane sealing rim sized to the 3.0L Duramax K47 air box. ACDelco does not publish a per-SKU ISO 5011 efficiency curve, so the filtration claim rests on GM's internal validation as the OEM specification rather than independent test data. The OEM cross-reference to GM 84121219 is confirmed across the GM catalog, PartsHawk, and DmaxStore, and owners report a routine three-screw swap that takes about 15 minutes.
Right pick for a 2020-present Silverado 1500 or Sierra 1500 owner with the 3.0L Duramax diesel who wants the genuine GM OEM filter at a price well below dealer parts-plus-labor and is comfortable doing the quick swap themselves. Skip if your truck has the gas 5.3L or 6.2L V8: those engines use a different element, so confirm your engine and air-box part number first. Also confirm fitment before ordering if you have a Tahoe, Suburban, Sierra, Yukon, or Escalade, since the broad GM application list spans several different filter shapes across those platforms.
Passive replacement component: no chemical exposure pathway during installation or removal, and no SDS applies. The product packaging carries a California Prop 65 warning, which is a metals and manufacturing-process label notice on a passive paper filter rather than a use-phase chemical exposure. Environment score of 4, reflecting a standard disposable filter lifecycle: a single-use paper-and-urethane element replaced on the GM service interval, with composite construction that goes to landfill at replacement with limited municipal recyclability.
An engine air filter only does its job if it actually fits your car, and the same truck can take a different element depending on whether it has the diesel or a gas V8. Before you buy, find the engine air filter for your vehicle in the CarCareTruth air-filter finder and pick your year, make, and model; we'll show the filters that fit it, ranked by our independent score and cross-checked against multiple catalog fitment sources.
It fits the 2020-present Chevrolet Silverado 1500 (and GMC Sierra 1500) equipped with the 3.0L Duramax inline-six diesel (LM2, later LZ0) and its K47 high-capacity air box. The OEM cross-reference is GM 84121219. If your truck has the gas 5.3L or 6.2L V8 instead, that engine uses a different filter; confirm your engine and air-box part number before ordering.
Yes. ACDelco's GM factory OE product line is the OEM filter; the A3244C is GM part number 84121219, the same element GM installs at the factory and supplies through Chevrolet and GMC dealerships. ACDelco is GM's in-house parts brand.
The A3244C is the large pentagonal element for the 3.0L Duramax diesel air box. GM's broad parts listing references full-size trucks and SUVs, but the gas 5.3L and 6.2L V8 trucks and the SUVs commonly use a different filter shape. Verify your specific year, engine, and air-box option against the GM parts catalog or a RockAuto / AutoZone application lookup before ordering rather than assuming a match.
Follow GM's maintenance schedule for your truck; for the T1XX 3.0L Duramax that is typically around 45,000 miles under normal driving, with earlier replacement under severe-service conditions such as frequent dusty roads, heavy towing, or short trips. Inspect the filter at every oil change and replace it sooner if it looks loaded.
No. The A3244C is the standard OEM replacement, not a performance modification, and ACDelco makes no horsepower or fuel-economy claims for it. Owners wanting more airflow sometimes switch to a washable cotton-gauze filter such as the K&N 33-2545 that drops into the same box; that is a different product with different trade-offs (higher flow, lower filtration efficiency versus OEM-spec).
The Amazon listing for ACDelco A3244C Engine Air Filter carries a California Prop 65 warning. California requires this warning on a very wide range of manufactured goods — including rubber, vinyl, plastic, and metal automotive parts — whenever trace exposure to any of roughly 900 listed substances (commonly phthalates or heavy metals) is possible, regardless of whether the specific product poses a meaningful health risk. As a passive accessory, ACDelco A3244C Engine Air Filter has no Safety Data Sheet, so there's no chemistry breakdown to translate beyond that.
