#How to install spark plug wire heat shields free#
On a related note, I called MSD and they are going to send me some free boots and boot shields, so A+ for their customer service if they pull through. I'm going to try to find a stock set as the after merket piece doesn't seem to cover the top as well as yours. With this type of shield, there shouldn't be any problems with heat damage. Looks like the 3rd item listed on the above posting. Pictures of the heat shield have been added to my album. Just to clarify, are you using the woven covers in conjunction with the stock heat shields or because your heat shields are missing like mine? If it is the latter this might be an easier solution! Thanks, I got them at a parts store up here but I think they're probably available at any speed shop. The spark plug wires and boots have stayed like new with these covers. I cut them so that they covered the boots out past the manifolds. I used a tube with a woven "asbestos" like material with a reflective coating on the outside. I do not have any photos or images depicting the stock shields, so I'm wondering if any replacements will work? I need a set of spark plug heat shields for my 1976 440. In addition, another benefit of a tubular wrap type heat shield is its serviceability, being able to be removed and then reinstalled once a component has been serviced.I decided to start another thread for this question so it would be searchable on its own. The obvious benefit of a wrap-type heat shield is its ability to be installed after a component has been previously assembled. Closure mechanisms include several types of Hook & Loop, snaps, zippers, straps with d-rings, hook and wire, tape and finally, heat- set. This type of design includes various closure mechanisms to achieve the tubular shape of the heat shield. The second type of tubular heat shields, are of a wrap design. When this situation exists, the tubular heat shield has to be oversized correctly to make allowance for the end fitting or the electrical connector Tubular heat shields are normally included in the design phase of a component thus avoiding the possibility of having to install a tubular heat shield over an end fitting or an electrical connector. Assembly aids, include the utilization of a device called a “bullet” which is a cone shaped assembly aid tool simplifying the assembly process. Tubular heat shields come in two different forms, a solid form, which when installed is slid along the length of the component to apply. In the racing industry, there is a focused effort to maintain a constant fuel temperature thus avoiding vapor lock and any incident of horse power loss due to hot fuel.
An example of this would be a fuel line, which has been exposed to too much heat throughout the length or surface of the fuel system, surpassing recommended operating temperature for fuel, thus creating vapor lock. Tubular heat shields are also utilized as an excellent means of insulating components from significant temperature drop, loss and/or temperature increase. Tubular heat shields are utilized for a variety of applications which include, but not limited to, excellent protection from radiant heat sources, significantly reducing component surface temperatures. In addition, to the tubular type heat shield application category, wiring harnesses, battery cables, air hose and spark plug boots would also be inclusive. tubing and the associated wire harness set. Applications include brake lines, fuel lines, coolant lines, A.I.R. The body of the article will focus on tubular designed heat shields.īy definition tubing, hose and cable applications are very generic terms utilized in the Automotive and Truck Industries to cover a broad spectrum of definitive applications for tubular heat shields. In this month’s blog from Thermal Control Products, we will be discussing Heat shields for tubing, hose and cable applications.
