NRW Design 4" Single Turbo Velocity Stack - BMW G80 M3 | G82 | G83 M4 | G87 M2 (S58) | F80 M3 | F82 | F83 M4 | F87 M2 Competition (S55)

The NRW Design 4" Single Turbo Velocity Stack is machined from a single piece of 6061-T6 aluminium and smooths and accelerates the air entering the turbo – a real improvement over a simple mesh turbo screen. A protective screen is machined directly into the stack, so it will not break up or degrade like band-type screens.

A 12AN port allows a catch can to be recirculated into the stack rather than vented to atmosphere, eliminating fumes and oil spray in the engine bay while creating negative pressure in the catch can and valve cover to help relieve crankcase pressure from blow-by.

Please note: For single turbo conversions with a 4" turbo inlet only – not suitable for factory twin turbo engines. Catch can systems using a 12AN outlet connect directly; others can be stepped to 12AN. Catch can, hoses and fittings are not included. Pairs well with the NRW Design S58 catch can kit, billet valve cover and single turbo kit.
