Q&A
Q: What’s the difference between early-1999 and late-1999.5+ Powerstroke models?
A: Early-1999 7.3L engines used a smaller intake elbow, different turbo compressor outlet, and smaller intercooler piping compared to the updated mid-1999.5–2003 design. This kit is built for the larger-diameter late-1999.5 and newer setup and will not fit the smaller early-1999 components.
Q: How can I tell if my truck is early or late-1999?
A: The easiest way is to measure the intake elbow. Early-1999 trucks have a smaller elbow diameter (about 2.5") and a different intake spider pipe layout. Mid-1999.5 and newer trucks use a larger elbow (about 3") and this updated style of charge piping.
Q: Does this kit fit with the stock intercooler?
A: Yes. This kit fits the factory intercooler as well as most aftermarket replacements that use OEM-style connections.
Q: Do I need tuning after installing this kit?
A: No tuning is required. This upgrade enhances airflow but doesn’t change fueling or boost targets.
Q: What is the benefit of stainless steel over aluminum or plastic?
A: Stainless steel resists heat, corrosion, and cracking far better than plastic or thin aluminum piping, ensuring long-term durability under high boost.
Q: What warranty comes with this kit?
A: All Sinister Diesel Charge Pipe Kits are backed by a 2-year warranty covering workmanship and materials.
