The Sinister Diesel 6.0L Power Stroke Intake Elbows replace the restrictive stock piping on 2003-2007 Super Duty or 2003.5-2005 Excursion with durable larger diameter CNC mandrel-bent aluminum tubing. This design prevents intake restriction for a noticeable performance increase while the stronger aluminum tubing and CNC-machined base plate is designed to handle higher boost levels. Finished in Sinister's high-gloss blue powder coat, this product provides a significant upgrade over the stock plastic unit. As with all Sinister products, the product was pressure tested at the company headquarters. This product is 50-state legal and is now on sale for $99!
