Weistec Releases M157 / M278 Biturbo, High Flow Air Filters
We will now be offering a drop in filter replacement. 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.

You can get a pair of BMC filters cheaper (part FB224/01). Why get these?

Are you sure those are for the M157? Because I just checked and they dont seem to be! |
Weistec,
Do you have any dynos to show the air filter/tune combo vs tune only? |
well i would assume 5-20 hp regardless, as thats what they say it might increase..... and i think with that range, its a tossup
