Welcome to kermaTDI.

                            Welcome to KermaTDI, the TDI Performance Leader.

We've set the standard for TDI performance and power upgrades since 2002 that's a decade, folks! Now with a complete selection of maintenance and repair parts, From performance tuning to tune-up, the only true one-stop shop for all your VW TDI parts needs!

If you haven't been here in a while, take a look around! There are quite a few new items.

We are your exclusive source for many products, now including the "new from billet" Colt Cams, new TDI Exhaust and Intakes, and the new Bosio DLC injectors.

Full line Koni and exclusive Shine Racing Service suspensions compliment our traditional area of strength, TDI performance parts and chiptuning that made us the pioneering leader in VW TDI DIESEL PERFORMANCE.

The Fratelli Bosio POWERPLUS diesel injector nozzles are the finest available anywhere in the world, and we are the exclusive importer in the USA and Canada. "Flavor of the month" imitators still can't match the quality and dependability of Fratelli Bosio, the foundation that made tdi PERFORMANCE possible. The new DLC nozzles have set new standards for reliability and industry-leading durability with ULSD fuel, and there's an industry-leading 300,000 mile warranty when installed and calibrated using our hot-swap program.

Our innovative combination of products come with unmatched support and deep knowledge that continues to set the quality standard that others can only attempt to emulate.

The revolutionary Q-loader flash tuner provides an exclusive end-user chip tuning tool, and it is a game-changer. Now it's incredibly easy for the customer to "chip" their own car through the OBD connector, all from the driver's seat, and KERMATDI brought this innovation to market.
