Product Overview
Upgrade your 7.3L Powerstroke’s performance and reliability with the Sinister Diesel Hot Side Charge Pipe. Designed as a direct replacement for the restrictive factory piping, this high-flow charge pipe improves turbo efficiency, airflow velocity, and overall engine performance. The result is better throttle response, increased horsepower, and reduced EGTs — ideal for towing, daily driving, or performance applications.
Each pipe is CNC mandrel-bent from high-quality stainless steel to maintain consistent diameter and perfect fitment. Reinforced 5-ply silicone boots rated to 400 PSI and stainless steel spring clamps ensure a tight, reliable seal under extreme boost pressure. The high-gloss Sinister Blue powder coat adds durability and a bold, professional look under the hood.
Why Upgrade to the Sinister Diesel Hot Side Charge Pipe?
The stock hot-side piping on the 7.3L Powerstroke is restrictive and prone to fatigue over time. Upgrading to the Sinister Diesel Hot Side Charge Pipe provides improved airflow, faster turbo spool-up, and better throttle response — giving your engine the power and efficiency it was meant to have. Built from premium materials, this pipe is engineered to last in even the toughest driving conditions.
Simple Installation

Frequently Asked Questions (FAQs)
Q: How do I know if my truck is early or late 1999?
A: Early 1999 7.3L Powerstroke engines (built in late ’98 to early ’99) used smaller turbo and intake connections. Mid-1999.5 and newer models switched to larger 3" piping. You can confirm by checking your build date or measuring your intake elbow diameter — this kit fits only the later version.
Q: Does this fit with the stock intercooler?
A: Yes, it fits both the factory intercooler and most aftermarket units that use OEM-style fittings.
Q: Do I need tuning after installing this pipe?
A: No tuning is required. This is a flow-improvement upgrade that enhances response and efficiency without changing fueling or boost targets.
Q: What finish does the pipe have?
A: The Sinister Diesel Hot Side Charge Pipe features a high-gloss Sinister Blue powder coat for corrosion protection and a clean, custom look.
Q: What is the warranty?
A: All Sinister Diesel Charge Pipes are covered by a 2-year warranty against defects in materials and workmanship.
