DIY AutoSpec 

Making engine wiring DIY easy

Welcome to DIY Auto Spec! We created this company with one mission in mind, to take one of the most daunting aspects of engine upgrades and swaps and make it easy enough for anyone to do in their garage. We’ve worked with both performance tuning shops as well as individuals looking to save money and do it on their own, and have helped both reduce cost as well as delivery time.
