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!
                                


 

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!

NEW! 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.

This upgrade also includes porting of the TB opening on the Windstar intake to better flow with the larger TB.

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!
