These Weistec filters are compatible with the 5.5 Biturbo and the 4.7 Biturbo (M157 and M278 engines). When analyzing the factory airbox and flow characteristics we found the placement of the filter in the box to be a significant restriction. Improvements in filter shape and positioning, combined with our very own high flow element provides a significant flow and power increase across all ranges of the engines power band.
For maximum results, the combination of our Weistec ECU flash and Weistec High Flow Air Filters is recommended.
