1. Purpose of the kit
This kit is a ‘cold air shaker intake hood scoop’ kit. As a multi-purpose kit, it does a number of functions. Some are strictly for looks, but others are for performance reasons.
For performance, this kit offers a less restrictive airflow than what would normally be pre-air filter box. Just by adding the kit you add additional airflow to the intake. Depending on other interactions, this may or may not be a limiting factor on your Mustang, however most stock 4.0L V6 Mustangs should benefit. If headers have been installed as well, it should certainly change the performance of the vehicle.
Also for performance, this kit brings ambient air to the intake. With stock configurations, intake manifold air temps can rise as the vehicle slows and the cooling system blows off excess heat by turning on the radiator fan. Without this kit the engines sucks in hot air, which can be 50 degrees or more above ambient.
Strictly for looks, this kit brings to mind the hood scoops of the 60s. And being a ‘shaker’, the scoop move with the engine as it strains against the engine mounts.
The purpose of this procedure is to provide an alternative installation manual to help individuals that are apprehensive about doing the installation themselves on their own vehicle. And to help fill in some of the blank spots left in the factory installation instructions.
This is NOT intended to be a replacement for the original factory install procedure, but rather another point of view to help clarify the factory procedure.
3. Parts of the process
There are a number of parts to the process of installing this kit, and I’ll break them down here before we start
- Move things out of the way
- Modify the air intake
- Cut the hood
- Mount the scoop
- Trim the hood
Moving things out of the way is mostly fairly simple, however the high voltage pack for the ignition system will need to be lowered. To do that involves cutting the bracket. Other things that need moved are pretty much just repositioning.
Modification of the air intake involves cutting a new hole in the air filter box and installing a new tube.
Cutting the hood is the most stressful part of the installation. This involves drilling, cutting, sanding, and manipulating the hood and thermal blanket. While there is little room for error, it’s not as difficult as it sounds, and hopefully the pics in this procedure will help.
Mounting of the scoop is fairly straightforward, but there are a few things to watch for.
Final trim is what makes your installation look sharp. It’s a fairly simple procedure, but you cannot cut corners if you want it to come out right.
4. Tools needed for this install
There are certain tools that you will need for this job. Some tools just make the job easier. Others make it possible. Not having the right tool can make the difference in a job that looks like a hack instead of a job that looks factory designed. While some tools can be improvised, having the right tool for the job always helps. Here is a list of what you’ll need. But remember, this is a recommended list, not a required list. Also, some additional tools may be required based on considerations of what is actually in your vehicle.
See above for tools required.
5. Cautions and Caveats
As can be imagined, there are a lot of cautions and caveats in this process. Most are common sense, but listing them here should just make sure they are remembered.
Always use eye protection when appropriate. That means anytime something could get into or near your eyes. While cutting is obvious, but also while doing sanding or working with chemicals.
Measure twice, cut once. You are cutting your HOOD!! Don’t rush and make a mistake. Replacement hoods are expensive. Measure again and again to make SURE you have it right. Then sit back, look at what you’re about to do, and make sure it’s appropriate and looks right. If in doubt, back off and take a break, then look again.
Keep metal parts from flying everywhere when cutting. Put a tarp or blanket on the engine if you are cutting the hood while still on the vehicle.
Make sure of what you’re cutting! This sounds simple, but if you just start cutting the hood and don’t take into consideration how deep the blade can go, you can end up with a seriously damaged intake manifold housing, or cut plug wires, or… The list can get long and expensive!
6. Getting Started – Moving things that are in the way
While the original manual suggest cutting the hood as the first step, I found it a lot less intimidating to do other things first. Make sure they fit, and then cut the hood. That means the first thing I did was get things out of the way.
Moving the coil pack.
Moving the coil pack involves lowering it by about an inch. The bracket that holds the coil pack is a ‘stepped’ metal frame. To lower the pack you need to cut the old frame into two pieces then bolt on a new piece that acts as the coil pack base to the original lower leg.
Remove the 4 coil pack bolts from the coil pack. These should be 7mm bolts. Lift the pack up off the bracket. Use a screwdriver to carefully pop the wire holders where they snap into the bracket and behind the intake manifold.
