The K&N 33-2183 is a high-flow, washable panel air filter for the Mercedes M113 4.3L / 5.4L V8 — C43 AMG, CLK430, CLK55 AMG and E55 AMG. This listing includes one filter, and the M113 uses two filter housings, so a complete change needs two. Oiled cotton gauze media, made in United States, drops straight into the factory housing in about ten minutes with no tuning and no modification. What You Get Part Number 33-2183 Quantity Included 1 filter — two required per vehicle Filter Media Oiled cotton gauze, pre-oiled Tune Required No Install Drop-in, 5–10 minutes, Torx driver required Reusable Yes — washable and re-oilable Made In United States Ships Within 2 business days 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. Hot air is less dense, so the engine makes less power, and rising IATs push the ECU toward pulling timing. Worst on a hot day when you are actually driving hard. 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 this performance air filter replaces.

No cutting, no wiring, no tuning. Wash with a cotton-gauze filter cleaner, rinsing from the clean side outward. Air dry at room temperature — no compressed air or heat — then re-oil lightly. Over-oiling is what contaminates a MAF sensor. Warranty, Shipping & Returns Warranty: K&N "No-Hassle" Lifetime Limited Warranty against defects in materials and workmanship.

The M113 uses two filter housings, one per bank. This listing is for a single filter, so add two to your cart if you are doing a complete change. Do I need a tune to run this?No. This is a direct replacement for the factory panel and works on a completely stock car. A tune is where the real power is, but it is not a requirement for fitting this. Will the filter oil damage my MAF sensor?Not when oiled correctly. It ships pre-oiled at the right level. MAF problems come from over-oiling after a cleaning — apply lightly, let it wick in, do not saturate. A dry synthetic filter is the alternative. Is a cold air intake better than this?On the M113, 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. A full intake kit earns its place once you are chasing airflow beyond what the factory box supports. How often does it need cleaning?K&N publishes a service interval of 50,000 miles under normal street driving. Clean it sooner if it is visibly loaded — dusty roads and construction traffic shorten that considerably. Does this fit the factory airbox without modification?Yes. It is an OEM-shape panel filter. Nothing is cut, drilled, relocated or removed, and the factory heat shielding stays exactly as it is. Mercedes Specialists · Real Enthusiast Support · US Stock
