Machined Ports: These manifolds have both the inlet and the outlet ports machined to match the factory gaskets. This allows for maximum flow, without compromising gasket performance.
Auxiliary Ports: An Exhaust Gas Temperature (EGT) probe port is incorporated into each manifold for easy installation of gauges or testing equipment. There are three additional cast in bosses provided to allow for alternate testing points.
These manifolds are compatible with the stock up-pipes, which allows the manifolds to be installed without having to remove the turbocharger down-pipe or the up-pipes.
Note: This system is not CARB exempt at this time and is not legal for sale in California or use on vehicles registered with the California Department of Motor Vehicle.

Advanced Flow Engineering, Inc. (aFe) produces high flow, high
performance air filters & intake systems for the automotive
industry. Founded in April, 1999, aFe was created to address an
obvious need in the automotive aftermarket industry: a lack of
choice for a high performance aftermarket air filter. We are a team
of engineers, machinists, production and sales people who believe
in the product we design. We each have years of experience in our
respective positions and together work to ensure that we have the
best product on the market. Our purpose was not just to be another
vendor that offers air filters, we chose to pay attention to those
finer details that set an aFe filter apart from the
