Installing Steeda High-Flow Air Kit
Steeda Autosports' High-Flow Air Kit for 4.6 Mustangs is a coolperformer
For years, cold-air induction systems have been available in variousforms and in all sorts of materials. Some models simply attach to thefactory ducting or mass air meter flange. Others replace the stockductwork with a high-flow version, either in plastic or some form ofmetal. And some take the cold-air induction concept inside the innerfender by relocating the air filter there. Due to the inner-fender roomand filter size, how-ever, some applications must have the filter placedunder the hood. No matter how you slice it, if you plan on adding otherperformance-enhancing breathing upgrades to your Mustang, a larger inlettract with a high-flow air-filter element is a must-have.
