Description
Radium Fuel Filter Kit - Ford Focus RS LZ 16-17
Application: Ford Focus RS (2016-2018) – not Focus ST
Part Type: High-flow fuel filter kit (OEM filter replacement)
Part Number: 20-0332-03, 20-0332-05
The Radium Fuel Filter Kit replaces the OEM fuel filter on the Ford Focus RS, which is plumbed between the electric and mechanical fuel pumps. The Radium filter is less restrictive than the OEM Ford unit, reducing pump load by approximately 0.2-0.38 bar (3-5.5 psi). Lower pre-filter pressure means lower current draw, reduced fuel temperature and increased fuel flow – Radium measured about 2% more flow with one aftermarket pump and 4.5% with two.
The kit installs in minutes with a couple of spanners and no cutting or drilling, and the filter handles alternative fuels such as methanol, ethanol and E85.
