K&N High-Flow Air Filter | Porsche 924 1978-1986 L4-2.0L | Sold Each
K&N 33-2570 High-Flow Replacement Air Filter is the drop-in element for the 2.0-litre 924. It fits the original airbox with no modification and replaces the paper filter for the life of the car.
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 binned, with up to 50,000 miles between cleanings under normal driving. Apply oil sparingly at service time.
