Description

The K&N 56-1270 Custom Air Filter Assembly is an iconic, high-performance filtration kit engineered specifically for classic horizontal carburettor layouts. This premium assembly fits dual-throat Weber 40 DCOE, 42 DCOE, 45 DCOE, and 48 DCOE configurations, as well as Dellorto DHLA series carburettors. Featuring highly polished chrome top and base plates, this kit delivers a period-correct motorsport aesthetic alongside modern, world-class high-flow performance.

At the core of the assembly is K&N's legendary oiled cotton-gauze filter element. It provides exceptional airflow straight into your engine intake tracts while ensuring maximum particle filtration to safeguard internal engine components. The deep 100mm element design is specifically favored by performance engine builders because it provides ample breathing volume around long internal velocity stacks or ram tubes, unlocking maximum torque and throttle response on classic road and track engines.

Key Features:

• Washable & Reusable: Pre-oiled and completely reusable—clean and re-oil using a K&N Recharger service kit.
• Chrome Finish: Mirror-polished heavy-gauge steel top and base plates provide excellent durability and style.
• Velocity Stack Friendly: Deep 100mm element depth allows internal air horns or ram tubes to breathe without restriction.
• Engineered Fit: Solid, flat mounting base plate provides an airtight seal directly against the carburettor intake flange face.
