Decent, but it's tough on the environment.

TL;DR Disposable pleated-paper filter · the genuine GM Original Equipment part (22844634) for the 2014·2019 Cadillac CTS V-Sport's 3.6L Twin-Turbo (LF3) intake. Fitment is OEM-exact for the V-Sport variant only; the standard 2.0L Turbo CTS and the 6.2L CTS-V both use different filters. Manufacturer-only filtration evidence (no published ISO 5011 curve for this niche SKU) and a thin owner reviews base keep the score honest rather than exceptional.
The A3185C is a disposable pleated-cellulose engine air filter classified by ACDelco as "GM Original Equipment" · the same part Cadillac installs at the factory and supplies through dealerships as GM 22844634. Construction is standard OEM: resin-treated paper media with a molded urethane sealing rim engineered to the CTS V-Sport intake box geometry. ACDelco does not publish a per-SKU ISO 5011 efficiency curve for this filter; the filtration claim rests on GM's internal validation as the OEM specification for the 3.6L Twin-Turbo LF3 engine · strong evidence of OEM-equivalence, but not independent third-party test data. The OEM cross-reference to GM 22844634 is confirmed across GMPartsDirect, Walmart, Zoro, partshawk.com, sdparts.com, and RockAuto. Service interval follows the Cadillac CTS V-Sport owner's manual: 45,000 miles under normal driving conditions, 22,500 miles under severe-service conditions.
Right pick for a 2014·2019 Cadillac CTS V-Sport (or V-Sport Premium Luxury) owner who wants the genuine GM OEM filter for the 3.6L Twin-Turbo intake and is comfortable paying an OE premium over generic aftermarket alternatives that fit the same box. Skip if your CTS is the standard 2.0L Turbo variant or the 6.2L supercharged CTS-V · both use different filters; verify your engine code is LF3 before ordering. Also skip if you own a 2020+ Cadillac CT5-V or any Chevy / GMC truck or SUV (Silverado, Tahoe, Suburban, Sierra, Yukon) · the A3185C does not fit those platforms; ACDelco publishes a different part number for each of those applications.
Passive replacement component · no chemical exposure pathway during installation or removal; no SDS applies. Environment score of 4, reflecting a standard disposable filter lifecycle: a single-use paper-and-urethane unit replaced on the GM-specified 45,000-mile 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 vehicle often takes a different part year to year. Before you buy, find the engine air filter for your vehicle in the CarCareTruth air-filter finder · pick your year, make, and model and we'll show the filters that fit it, ranked by our independent score and cross-checked against multiple catalog fitment sources.
The A3185C fits the 2014·2019 Cadillac CTS V-Sport and V-Sport Premium Luxury · specifically the 3.6L V6 Twin-Turbo (LF3 engine code) variant. It does NOT fit the standard 2.0L Turbo CTS or the 6.2L supercharged CTS-V. Confirm your engine code is LF3 before ordering. The OEM cross-reference is GM 22844634.
No. The A3185C is a Cadillac CTS V-Sport-specific filter (3.6L Twin-Turbo intake box). Full-size GM trucks and SUVs use different ACDelco filters · typically A3134C, A3179C, or A3217C depending on the year, engine, and trim. Verify your vehicle's correct part number against the GM parts catalog or the AutoZone / RockAuto application lookup before ordering.
Yes. ACDelco's 'GM Original Equipment' product line is the OEM filter · same part GM installs at the assembly plant and supplies through Cadillac dealerships as part number 22844634. ACDelco is GM's in-house parts brand.
Cadillac's owner-manual service schedule specifies engine air filter replacement at 45,000 miles for normal driving conditions and 22,500 miles for severe-service conditions (frequent short trips, heavy dust, towing). Inspect at every oil change and replace earlier if visibly loaded.
No · the A3185C is the standard OEM replacement, not a performance modification. The 3.6L Twin-Turbo intake box is already engineered for the V-Sport's airflow demand. Owners looking for an aftermarket airflow change typically swap to a K&N 33-5028 washable cotton gauze filter that drops into the same housing; that's a different product with different trade-offs (higher flow, lower filtration efficiency vs. OEM-spec).
