K&N High-Flow Air Filter | Porsche 912E 1976 / 914 1973-1976 / 924 & 924 Turbo 1977-1982 | Sold Each
K&N 33-2003 High-Flow Replacement Air Filter covers the four-cylinder end of the seventies and eighties Porsche range — the 912E, the 914, and the 924 in both naturally aspirated and turbocharged form. It drops into the factory airbox with no modification.
Oiled cotton, the original high-flow media. K&N layers oiled cotton gauze between epoxy-coated aluminium mesh, rated to flow up to 50% more air than a disposable paper filter and tested in an ISO 5011 laboratory for filtration efficiency. Supplied pre-oiled; washed and re-oiled with a K&N Recharger kit rather than replaced, with up to 50,000 miles between cleanings under normal driving.

Note: K&N lists 33-2003 without a multi-filter annotation — it is supplied as a single filter. Clean and re-oil with a K&N Recharger kit; use K&N air filter oil only, apply it sparingly, and let the element dry fully before refitting.
Installation Instructions:
Parts availability matters on a 912E. This is one you buy once and keep washing.
