The Sinister Diesel 7.3L Power Stroke intake manifold serves as an upgrade to your performance and appearance. It replaces the restrictive stock piping on your 1995.5-2003 Ford F-250 or F-350 Super Duty with larger diameter CNC mandrel bent aluminum tubing. The increased diameter and large radius bend prevents restriction within the intake for a noticeable increase in performance and turbo spool. Meanwhile the stronger aluminum tubing and CNC machined base plate is designed to hold higher boost levels. Finished with our eye-catching Sinister Blue powder coat, the Sinister Diesel 7.3L Power Stroke Intake Elbow provides an upgrade over the stock cast unit. Like all Sinister Diesel products, it was designed and pressure tested at our California headquarters and is backed by the legendary Sinister Diesel Lifetime Warranty.
