| Plug and Play means different things to different people and companies. Therefore we felt it was necessary to define what it means to TBMSport.
"Plug and Play" installation means CONSIDERATION. FIRST consideration is attributed to the applicable vehicle's original components and their attributes; in other words, the various components' locations, functions, and fitments.That means TBMSport parts and connections must fit and seal exactly like the OEM parts. SECOND consideration is given to the installer and service technician. How can the installation process be as easy as possible and how do you insure that maintenance and diagnostic services cause as little confusion as possible? THIRD consideration is given to the present and future vehicle owners. Quality products have always been a top priority for TBMSport. Therefore, fit, finish, and function must not negatively impact the vehicle's resale value. Therefore, components must always be as easy to return to OEM specifications and condition with the same level of ease that it took to install it.
THAT is "TBMSport Plug and Play"
