Air Intake Header Wedge
Added 2006 May 06
A number of people have been asking whether we could supply
the Wedge for the air intake header shown in Tom's air intake page -
Tom's Air Intake System
As a result we have designed a wedge that can be machined at
reasonable cost - it is still not a simple machining job.
This wedge provides a 20°
change in the angle of the throttle body so that, on a 2WD Vanagon you can use a
stock Subaru air intake tube and it will fit below the engine cover lip. It does
require a small section of the fire wall be cut out to make room. It fits nicely
and provides the full air flow that Subaru intended.
Here is what the wedge kit looks
The kit includes the wedge, one
new Subaru air intake gasket, four bent studs and the
Since the holes in the air intake
header are tapped and the bolts need to pass through
the throttle body holes bent studs have to be
fabricated to facilitate assembly and bolt up. The
installation looks like this when you have the wedge
installed and are ready to install the throttle body.
The slotted holes are the critical part of this design
- allowing room for the bent studs but at the same
time holding the wedge in it correct position.
This arrangement may not be of
interest to everyone but it does allow one to use the
stock Subaru intake tube without alteration as can be
seen in Tom's
Air Intake System . These wedges are in stock and can
be shipped immediately.
