Lieferumfang
1,8T Stage III+ Passat/A4
This page focuses on the items that are included with
the B5 A4 Stage III+. Because this kit is so extensive,
it would be impossible to highlight all of the items that
are included with it.
Exhaust
Manifold
The Stage III+ exhaust manifold is investment cast out of
Inconel, a high-temperature nickel alloy. The manifold was
designed in CAD and optimized using computational fluid dynamics
(CFD) software. What this means to the end user is the ultimate
in performance and reliability.
Custom
Silicone Inlet Hoses
These CAD designed hoses are designed to replace the factory
hoses between the airbox and turbocharger, and the turbocharger
to the factory cross-over pipe. APR both designs and makes the
tooling for these items in house, using a combination of our
CMM tool, SLA machine, and CNC machine.
MAF Housing
The mass air flow sensor (or MAF sensor) measures the amount
of incoming air and sends an analog signal to the engine computer
representing the amount of air flowing into the engine. The
MAF sensor is mounted in a cylindrical housing that is sized
according to engine displacement and maximum power output. We
replace the stock MAF housing with a cast aluminum unit to allow
the proper metering of the additional airflow and to minimize
pressure losses. The cast aluminum housing is CNC machined to
exacting tolerances and powder-coated to inhibit corrosion.
Honeywell/Garrett
Turbocharger
Representing the latest in turbocharger technology, a Garrett
Ballistic series turbocharger is the only choice for a premium
turbocharger system. APR is unique in that we deal directly
with Garrett turbochargers rather than buying turbochargers
through turbocharger supply houses. Our engineering-house distributor
status with Garrett turbochargers means that we receive assistance
from the manufacturer on technical issues and work with Garrett
engineers on specifying the optimal turbocharger for each application.
Flow
Straightener
The correct flow straightener was sourced to ensure laminar
air flow through the mass air flow sensor. This is important
for proper air flow metering at all flow levels. The flow straightener
is sandwiched between the MAF meter and the air horn and is
held in place by a retaining clip.
APR Fuel
Injectors
APR sent many hard hours with a major OEM manufacturer to develop
a fuel injector that has the same spray pattern as a stock injector,
but with a very high flow output.
