We have seen gains of up to 10 RWHP from Tube Style intakes on the M54. Injen dyno tested the system on a 328i and got a gain of 6 RWHP.

The system is CARB legal.

Quoted from the instruction manual that is included in the kit:

"This intake system was Dyno-tested with an Injen filter and
Injen parts, the use of any other filter or part will void the
warranty and CARB exemption number"
