Powerplus 502 nozzles are a significant upgrade in fueling for ALH TDIs. They are nominally the same size as .216s, but flow more fuel because of superior tip design. This set of 4 nozzles will work well in a stock TDI, providing about a 15 HP and 25 ft./lb. power increase. They will also work in chip tuned cars, although they may tend to smoke with a stock turbo and a chip. These fit non-PD engined TDIs. They include injector seals.
Genuine Bosio product, direct from Italy. .216 hole size.
