Pipercross Viper Carbon Fibre Airbox Cold Air Intake Induction Kit for BMW 3 Series E46 316i 318i M43 - Sealed Ram Air Performance Foam Filter Upgrade | Performance Air Filter Kit

Viper Carbon Intake System by Pipercross for BMW E46 316i and 318i with M43 Engine

Give your four-cylinder E46 the breathing it deserves. The Pipercross Viper sealed carbon intake draws cool air from outside the engine bay to reduce heat soak and improve throttle response. Expect crisper acceleration, a deeper induction note and a tangible step up in drivability compared with the restrictive factory airbox.

Built around a lightweight carbon housing and a high-flow multi‑layer foam element, this performance intake system offers significantly greater airflow than a paper element while still filtering effectively. It is a superb bolt-on upgrade for daily road use and spirited driving alike.

Key reasons enthusiasts choose this carbon intake

• High flow intake system for sharper response and stronger mid‑range pull
• Sealed carbon canister helps feed cooler, denser air for more consistent performance
• Triple‑layer foam element flows freely yet protects the engine in real‑world conditions
• Proven airflow increase versus standard paper filters
• Serviceable and reusable filter for long‑term value
• Supplied with vehicle-specific hardware for a straightforward, bolt-on install
• Durable construction suitable for fast-road and trackday use
• Lifetime warranty on road-use filters

How the foam element works

The graded three‑layer design captures debris progressively through the depth of the media, so the filter keeps flowing as it loads. Where pleated cotton or paper elements can clog and restrict, the Viper’s foam maintains airflow to keep your M43-breathing E46 feeling keen and responsive for longer intervals between cleans.
