The aFe Pro DRY S 31-10289-MA is a pair of high-flow, washable panel air filters for the Mercedes-AMG M177 4.0L V8 BiTurbo — C63, C63 S, GLC63, GLC63 S and G550. This listing includes both filters, because the M177 uses two filter housings and a complete change needs both. Synthetic, oil-free media, made in United States, drops straight into the factory housings in about ten minutes with no tuning and no modification.

Cold Air Intakes Aren't Pulling Cold Air
Ironically, "cold air intakes" use open cone filters, exposing them to hot air from the engine bay. When IATs rise, the ECU then pulls timing, reducing power when you are driving hard or doing repeated pulls.
The factory Mercedes airbox already channels cold air from the outside. Sealed, ducted to the grille. The paper panel inside is the only real restriction, and that is what these performance air filters replace.

Install & Maintenance
Undo the Torx screws on each airbox lid, lift the lid, swap the filter, and put it all back together. No cutting, no wiring, no tuning.
No oil, ever. Wash with filter cleaner and water, rinsing from the clean side outward, air dry at room temperature, and reinstall. Nothing to re-oil means nothing to over-oil, so the MAF question never comes up.

Questions
How many filters does my car need?
Two. The M177 uses two filter housings, one per bank. This listing ships both, so you are not hunting for a second panel after the box arrives.
Do I need a tune to run these?
No. These are direct replacements for the factory panels and work on a completely stock car. A tune is where the real power is, but it is not a requirement for fitting these.
Will this contaminate my MAF sensor?
No. Dry media uses no oil, so nothing migrates downstream. This is the filter to buy if MAF contamination is what's keeping you off a washable filter.
Is a cold air intake better than this?
On the M177, no. The factory box is already sealed and ducted to outside air, so the paper panel is the restriction rather than the box. An open cone gains a little peak flow and gives up intake temperature, which is the wrong trade on a turbocharged engine. A full intake kit earns its place once you are chasing airflow beyond what the factory box supports.
How often do they need cleaning?
aFe publishes a cleaning interval of roughly every 20,000 to 30,000 miles, sooner if you have been through extremely dusty or dirty conditions.
Do these fit the factory airbox without modification?
Yes. They are OEM-shape panel filters. Nothing is cut, drilled, relocated or removed, and the factory heat shielding stays exactly as it is.
