Because race car. This aFe Takeda Momentum intake is built for the B58 in Z4 M40i (G29, 2019+) and GR Supra (A90, 2020+), not a generic 'turbo I6' placeholder.
Stage 1 fast road or track day: Pro 5R (56-70050R) gives +14 hp / +22 lb-ft; Pro DRY S (56-70050D) gives +6 hp / +12 lb-ft - no tune required, but gains stack cleanly with stage 2 or decat setups
Fits G29 and A90 chassis only: no MK7, no F30, no N55 - this isn’t a parts-bin grab. Uses OEM mounting points, zero trimming, full bolt-on
Heat-resistant XLPE housing seals against engine bay heat, outflowing stock by up to 16% - critical for sustained B58 boost response on track days or fast-road runs
Choose your filter intent: Pro DRY S for daily driver or show car (oil-free, low-maintenance); Pro 5R for track day or stage 2 builds where maximum airflow matters more than service intervals
