The Industrial Injection Performance Extrude Honed Nozzles start out as a genuine Factory OEM injector nozzle which is then extrude honed and balanced to flow anywhere from 15% to 100%. These nozzles work great in a completely stock all the way up to a fully built competition truck. We typically see a 1-3MPG increase in fuel economy. We balance the nozzles to a tighter tolerance than the original manufacturer and have put a lot of time into making these the best nozzles money can buy. Designed to give you the extra fuel your truck demands during extreme race and sled pull competitions nozzles sold individually.
