Replace your restrictive stock intake elbow in your 7.3L Powerstroke with the larger diameter CNC mandrel bent aluminum Sinister Diesel Intake Elbow kit. The increased diameter and large radius bend prevents restriction within the intake for a noticeable increase in performance and turbo spool. The stronger aluminum tubing and CNC machined base plate is designed to hold higher boost levels. Finished with either Sinister Blue or Gray powder coat, the Sinister Diesel 7.3L Power Stroke Intake Elbow provides an upgrade over the stock intake system. This kit is also available with or without replacement boots and clamps. If your boots are oil soaked, it is a good idea to reaplace those as well to ensure a leak free seal.
