Our 4i"race air box system has been designed for extreme power levels. Utilizing the area normally occupied by the battery we have been able to design the ultimate high horse power intake. The air box uses a massive 6in internal diameter K&N filter which mounts onto a 6in to 4in 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.
For those that have upgraded their turbo to a 4in 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.
