The Process West 4" Race Air Box System has been designed for extreme power levels. Utilizing the area normally occupied by the battery, Process West have been able to design the ultimate high horse power intake. 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 molded 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
- Utilises the stock location for the battery
For those that already use this kit, but have upgraded their turbo to a 4" inlet (0.70a/r housing), Process West offer a 4" to 4" silicon hose. This hose simplifies the installation of larger turbos, and can be found in the related items (P/N: PWBACAI03-HOSE)
