About Kerma TDI

Welcome to Kermatdi! KermaTDI is the combined effort of a group of really bright and enthusiastic people who are passionate about the turbo diesel market.

Headquartered in Colorado, we first made our name by introducing nozzle upgrades to the diesel world in 2002 more than a decade ago and focused our resources on Turbo Diesel Innovation. By so doing, we started an entirely new automotive performance niche. The existence of more powerful fuel injectors drives the need for supporting components, such as turbos, camshafts, and clutch upgrades, and of course ECU tuning to tie it all together. After over a decade of supporting the turbo diesel community we remain the premier vw/audi diesel performance part provider, and a primary innovation center, driving many aspects of diesel performance trends worldwide.
