Process West 4" Race Air Box Suit Stock Turbo Inlet (3")
- K&N Filter Supplied
- 6" to 4" bell mouth
- Utilises the stock location for the battery
- Suites factory turbo
This Process West 4" race air box system has been designed for extreme power levels utilizing the area normally occupied by the battery.
The air box uses a massive 6" internal diameter K&N filter which mounts onto a 6" to 4" bell mouth which connects to a internally wire re-enforced moulded silicon hose down to the turbo. This combination gives maximum flow for power levels of 500rwkW+.
The air box can also be used for high mount turbo configurations. The 4" OD air box outlet is at the approximate height of most high mount turbo compressor inlets so a simple section of pipe is all that is needed to use the air box for high mounts.
For those that have upgraded their turbo to a 4" inlet (0.7A/R cover) we offer a 4" to 4" silicon hose. (PWBACAI03-hose)
This hose simplifies the installation of larger turbos. The hose can be purchased separately or part of an initial air box purchase.
