Sinister Diesel Cold Side Charge Pipe – 7.3L Powerstroke
Fits 1999.5–2003 Ford F-250 / F-350 / F-450 / F-550 Super Duty & Excursion
Note: This kit will NOT fit early 7.3L Powerstroke engines built in late 1998 or early 1999. Early 1999 trucks use a smaller intake elbow and different intercooler pipe routing. Mid-1999.5 and newer trucks have larger diameter piping and intake connections—this kit is designed specifically for those later configurations.
Key Features
• Stainless steel construction for superior durability and heat resistance
• CNC mandrel-bent 3" tubing for unrestricted airflow and precise fitment
• 5-ply silicone boots rated to 400 PSI for maximum pressure and longevity
• Stainless steel spring clamps for a secure, leak-free seal
• Powder coated in Sinister Blue for corrosion resistance and bold style
• Direct bolt-on design—no cutting, welding, or modifications required
• Backed by a 2-year Sinister Diesel warranty
Product Overview
Unlock the full potential of your 7.3L Powerstroke with the Sinister Diesel Cold Side Charge Pipe. Designed for 1999.5–2003 models, this upgrade replaces restrictive factory piping that limits airflow and performance. With a larger 3-inch diameter and smooth mandrel bends, it improves airflow velocity, reduces EGTs, and enhances horsepower, torque, and throttle response.
Each pipe is CNC mandrel-bent from premium stainless steel for superior strength and heat resistance. 5-ply silicone boots rated up to 400 PSI and stainless steel spring clamps ensure a tight, leak-free fit under extreme boost conditions. Finished in our signature Sinister Blue powder coat, this charge pipe delivers both performance and a show-quality appearance under the hood.
Why Upgrade to the Sinister Diesel Cold Side Charge Pipe?
The factory 7.3L cold-side charge pipe is restrictive and prone to fatigue under pressure. Upgrading to the Sinister Diesel version improves airflow, turbo spool, and throttle response. The result is a stronger, smoother, and more efficient engine—perfect for towing, daily driving, or high-performance setups.
Simple Installation
Installation is quick and straightforward using basic hand tools. The kit’s pre-formed silicone boots and spring clamps ensure a precise, leak-free fit. No cutting, welding, or fabrication required—this charge pipe bolts directly into OEM locations.

Frequently Asked Questions (FAQs)
Q: How do I know if my truck is early or late 1999?
A: Early 1999 trucks (built late ’98 to early ’99) use a smaller intake elbow (~2.5”) and different intercooler routing. Mid-1999.5 and newer models have a larger 3” intake elbow and updated piping—this kit is made for those. Check your build date on the driver door sticker or measure your intake elbow before ordering.
Q: Will this fit the factory intercooler?
A: Yes, it fits the OEM intercooler as well as most aftermarket units with stock-style connections.
Q: Do I need custom tuning after installing?
A: No tuning is required. This kit increases airflow and efficiency without changing fueling or boost targets.
Q: What finish does it have?
A: Each charge pipe is finished in our high-gloss Sinister Blue powder coat for corrosion protection and a clean, custom look.
Q: What is the warranty?
A: The Sinister Diesel Cold Side Charge Pipe is covered by a 2-year warranty against manufacturing defects and workmanship issues.
