Dinan Carbon Fiber Turbo Inlet Pipes - BMW M5 / M8 (F9x) 2018-2025 - Pair

Dinan Turbo Inlet Pipes replace the restrictive plastic factory inlets on the S63-powered F90 M5 and F9x M8, opening the path to each turbocharger. Built from gloss UV-coated 2x2 carbon fiber with an aluminum adapter that reuses the factory locking connection, each pipe offers the largest possible cross-section from filter to turbo, a 200% increase in volume at 105 cubic inches per side versus 35 stock. On cars with factory airboxes they add an average of 11 WHP and 13 lb-ft from 2000 RPM to redline, up to 22 WHP and 18 lb-ft at 6500 RPM, and work with either the stock or Dinan intake.
