A replacement Trifoam® Filter Unit for the Racing Line R600 (gen 3B MAF) Intake. This Trifoam® option is the ultimate filter unit that will deliver optimum power gains. This filter can only be fitted into the Racing Line R600 Intake that is specifically for 2.0 TSI EA888 gen 3B ‘MAF’ engines (including those previously fitted with a Cotton filter unit). This Trifoam® Filter replacement unit is specifically for 2.0 TSI (190hp) EA888 gen 3B R600 Intakes. All other R600 replacement filters have a separate part number. This is a simple straight replacement filter unit, ready to drop into any existing gen 3B MAF R600 intake. The choice of Trifoam® filter material gives you the highest airflow for the best possible power for more of the time. However, as a high performance part, regular maintenance or replacement is essential to keep it in peak condition using the Racing Line Filter Refresh Kit to clean and reoil it, or ideally replacement of this filter unit every 10,000 miles. With the option of either this Trifoam® R600 filter or the Pleated Cotton option, the choice is yours – note that the alternative Cotton Filter option is a robust 'fit and forget' unit that will not only give great initial power output but requires no maintenance to last you for many years. Note: fitment is only for Racing Line R600 gen 3B MAF Air Intakes.
