The Windstar Intake Conversion Kit (99-04
3.8 Mustangs)
Fits
under stock hood, retains EGR and
PCV systems.
 About
the Windstar Bolt-On Kit...
The
96-98 Ford Windstar's came with a much more efficient plastic
composite upper intake manifold. This kit includes everything you
need to adapt the Windstar intake to your 3.8 Mustang.
Gains of over 7HP and
15FT/LBS! With other mods your gains can be even greater. Compare the power numbers from the
96-98 Windstar to the 99-04 Mustangs which share the same engine.
Windstar Kit vs Intake Spacer >
For those of you watching your weight
you will be glad to know that the Windstar is over 50% lighter
than the stock intake. 14lbs vs 6.5lbs!
NEW! Improved Throttle Body Design
In order to limit the throttle arm deflection and improve
throttle response I've come up with a new design that braces the
throttle body extension arm with a brass bushing. This vastly
improves rigidity and even throttle response. Now standard on all
01-04 kits. Existing customers want to upgrade? Shoot me an email
for a special deal!
Windstar Intake Kit Dyno Results
Check out this dyno comparison showing before and after
dyno's with the VAP Windstar intake kit. Johnny's 2003 3.8l
with 10psi Procharger showed an impressive 10HP and 26FT/LB
gain with only the Windstar Intake kit!

65mm Throttle Body Upgrade & Porting!
I've just started modifying the 65mm GT throttle body for use with
the Windstar kit as a more affordable alternative to the $200+
aftermarket 65mm throttle bodies. These TB's are modified using an
updated jig to maintain perfect TB geometry. Due to the GT TB cable
style, this is only available for the 01-04 Mustangs. 99-00 would
need to swap throttle cables to the newer 01-04 cable.
Ok, But How Does it Work?
Why will this intake give you more torque and horsepower? Well, its
all about optimizing the intake runner length. Looking at a side by
side view of the stock intake vs the Windstar you can see that the
Windstar has much longer runners. (read this article to see
why runner length affects power output) This is the same
principle that allows intake spacers to work.
The Windstar acts similar to an intake
spacer, giving you more power by increasing the runner length.
Longer runners give low end torque and shorter runners give more
high RPM torque. (this is why Ford has a split-port intake with two
runners per cylinder) The limitation with intake spacers is they can
only lengthen the runners so much before the short runners become too
long and you start to loose high RPM power. As you can see
in the side by side picture; the Windstar has much longer "long" runners while
keeping the "short" runners short. This allows you to gain
low RPM torque as well as high RPM power. Combine that with the
better flow and the heat resistant composite and you get a wide range of
power gain!
Introducing the new v3.0
Windstar Kit! New Design Improvements:
- Re-designed intake pipe. Now
smaller and lighter. Easier install with large air filters.
- Updated side bracket. Fixes
issue with slow cruise control response.
- Improved throttle body
modification. A precise jig now locates the throttle arm for the
perfect throttle geometry every time.
- New angled TB spacer! Tilts
the throttle body down by 1/2" to give additional hood clearance
and prevent rubbing. Now you can leave the hood insulator on! See
the before and after animation >
- Fits under stock hood, no
cutting or hood scoop required!
