Torque diesel Motorsports is an innovative manufacturer of performance diesel parts and their new line of injectors are truly special. Their injectors are NOT a simple extrude-hone of the nozzles but are instead manufactured using all Bosch parts calibrating the housing and internals for their power upgrades. This creates some of the cleanest burning and most reliable performance injectors available at a cost far below any comparable brand out there. Made in the USA, Torque Diesel Motorsports is standing behind their new lines of injectors with an unheard of 15-Month Unlimited-Mile Warranty with a 90-Day Labor Guarantee.
