Torque Diesel - Stage 1 Performance Injector - Single - 2004.5-2005 GM 6.6L LLY Duramax TDM04S1

Part # TDM04S1

TDM's new approach to building injectors is producing a cleaner burning and more reliable performance injector than anywhere on the diesel market.

TDM injectors are hand built by OE trained technicians on OE Certified Equipment using only GENUINE OE PARTS! NO AFTERMARKET JUNK! TDM injectors are engineered to perform at the highest level. These are not simply a stock injector with extrude honed or EDM nozzles installed in them. TDM injectors are engineered to perform and use an SAC nozzle. Each injector’s internal components have been re-engineered to allow more fuel flow while operating under the same rules as the stock injector, similar to MADS Big Bang Injectors but at a fraction of the price and with a superior warranty. Each injector is matched with a specially designed OE nozzle that will accommodate the internal changes to allow the injector to function like is was originally designed to do. TDM injectors are precision matched and balance to 1.5% of each other. TDM injectors are built the same way every time. The flow rate from our first built injector is the same as our 500th built injector! No other company can do that and keep the balance rates that tight!

Sac nozzles contain a dead volume, or fuel sac, below the needle seat. The nozzles holes are created using Electro Discharge Machining (EDM). The benefit of this design is longevity and robustness. The tip shape allows for greater thickness between the needle seat and the top of the sac. The increased thickness creates greater tip strength and allows for shorter sprayhole lengths. Shorter spray-hole lengths increase the exit velocity of fuel and promote greater fuel atomization by forming smaller more circular fuel droplets. Additionally, the available needle sealing area is larger than a VCO nozzle, meaning the sac nozzle is less likely to drip.

Our 6.6L LLY Duramax stage 1 injectors are capable of supporting +700hp with the proper power and tuning upgrades and at the same time they will support a simple 80HP increase. TDM injectors are engineered to perform like a stock injector throughout the power band. This makes the injector very efficient which in turn minimizes smoke, minimizes exhaust gas temperatures, and makes for a very smooth running engine. TDM injectors are ready for you to command them. They have a top end limitation but you are ultimately the one who decides how much power you want them to deliver. So whether you need some power to tow your camper or you are looking for weekend warrior fun, TDM injectors are your answer!

TDM injectors are backed by the best warranty in the country! Our injectors come with a 15 month unlimited mile warranty with a 90 day labor coverage. We have a “No Hassle Warranty” policy with these injectors. Each application has specific details so please ask about the warranty program for your vehicle.
