Why Buy Charge-Air Parts from CPP Diesel?

03–07 specific: Components chosen for 5.9L routing, common 3.0–3.5" tube sizes, and HE351/aftermarket turbo layouts.
Brands that work: Mishimoto, Banks, BD Diesel, and CPP in-house solutions for stock or 600+ HP builds.
Towing & performance: Lower IATs and stronger connections for fewer blown boots and more consistent spool.

Tech Notes & Fitment

Year splits: Banks systems are year-specific (03–05 vs 06–07). Match your build year to the correct kit.
Piping size: Many upgrades step to 3.0–3.5" tubing; verify coupler/clamp sizes when mixing parts.
Boot/clamp strategy: Use multi-ply silicone with constant-tension or quality T-bolts; re-torque after heat cycles.

Frequently Asked Questions

Will an upgraded intercooler reduce EGTs when towing?

Yes—denser charge air generally helps lower EGTs and improve repeatability on long grades, especially when combined with clean tune and healthy fuel supply.

Do I need new boots/clamps with metal boost tubes?

Recommended. Fresh multi-ply silicone and quality T-bolts help prevent blow-offs under higher boost, particularly on tuned or towing trucks.

What’s the difference between a “kit” and a “core only” intercooler?

“Core only” replaces the intercooler; a “kit” includes the core plus matched boost tubes/boots and often installs more quickly with better overall fit.
