VTT 2021+ BMW M3/M4 High Performance Drop-In Air Filter Upgrade

VTT is proud to offer high-performance drop-in replacement filters for the 2021+ G8X M3/M4. These filters are custom-made for VTT. They are made with a heat-resistant silicone base, a high-flowing cotton weave element with a pre-oiled design to catch contaminates but allow free flow. On the dyno, we saw more than 13WHP gains with these filters and our Carbon Fiber intake Tops. These filters will also work perfectly with the stock tops. We recommend removing the pre-filter for best flow if the stock top is used. We offer them in two colors. Red, and Black

Features:

• 50 States Emissions Legal
• Easy to install 15-30 minutes even for a novice
• Filters can be cleaned forever meaning never buy new filters
• Up to 13WHP gains
• Completely reversible if you ever want to remove

None of this we did 1 run each, and are claiming big gains nonsense. We did 7 full runs. The first 3 with Stock lids, and Factory Filters. We ran these back to back in 5th gear, and you can see heat soak is present on runs 2-3. After the first 3 runs, we let the car cool down, left the stock filters in place, and swapped on the VTT Carbon Lids. We ran that once just for curiosity’s sake. The car indeed picked up power even with the stock filters. We then let the car cool down again as we swapped the VTT Filters in. We then ran 3 times back to back, again heat soak is present on the 2nd-3rd run. As you can see the temps were rising as were swapping parts around, and even with a 4 degree higher temp difference for the later runs they still picked up an average of over 13WHP. You are ALWAYS going to see the most power after a cool down which is why we run it 3 times each.

Average of Runs 1-3 726.67WHP

Average of Runs 5-7 739.93WHP

Net Increase 13.26WHP

Please note: these tests were ALL done with our GC silicone intake system on the car, but we are simply focused on the delta. Everything remained exactly the same except the filters and lids
