The K&N E-3341 is a washable, reusable High-Flow element in an oval, side-draft shape measuring 7 x 4-1/2 inches. The manufacturer describes its layered, oiled cotton media as engineered to improve airflow and capture contaminants, which is the core of the K&N platform. Compared with a disposable paper element, this filter can stay in service for the life of the vehicle, and the manufacturer backs it with a No-Hassle Lifetime Limited Warranty. That warranty and reusability are what justify the higher price over a stock-style paper replacement. The manufacturer's custom carburetor listing places this 4-1/2 x 7 side-draft oval size on Dellorto DRLA, Mikuni-Solex, and SK Racing applications, so it suits a carbureted engine built around a Dellorto or Mikuni-Solex intake. Buyers searching for a K&N E-3341 oval carb air filter, a side-draft oval air filter for Dellorto DRLA, or a washable oval carb filter for a Mikuni-Solex setup will find this part matches those applications.
Before ordering, confirm your carburetor model and whether your application is street-legal with the manufacturer, since details on emissions-controlled street use vary across sources. For installation, no dedicated install sheet for this part number was found. The manufacturer's install sheets for other oval-style K&N filters emphasize cleaning the housing and sealing surface and fully seating the filter so it seals correctly, and the same care should apply here.

This is a drop-in element for an existing air box, so installation is typically a straightforward DIY job with basic hand tools. No part-specific torque or fastener list was confirmed for this number. Following the manufacturer's general guidance for oval K&N filters, clean the housing and sealing surface, seat the filter fully, and reinstall the lid so the element seals. The manufacturer warns that a filter that does not seal can allow unfiltered air into the engine, so check the seal after installation.
