Perkins is one of the world's leading diesel engine manufacturers, supplying power units to Massey Ferguson and many other major OEMs. The Perkins 1004.4T, 1004.40TW, and 1006.6T are turbocharged diesel engines powering Massey Ferguson's 680, 6100-series, and 8100-series tractors — high-horsepower workhorses trusted by farmers worldwide. When injectors fail on these engines, you'll experience rough running, misfires, excessive smoke, hard starts, and reduced fuel economy — symptoms that directly impact field productivity. This 4-piece brand-new aftermarket injector set covers all four cylinders in a single order, precision-matched to OEM spray pattern and injection pressure for the Perkins 1004/1006 engine family.
