Take your Ford 7.3L Powerstroke’s crankcase ventilation system to the next level with the Swag Performance Billet Aluminum Crankcase Ventilation Adapter — engineered for enthusiasts who demand premium performance and long-term reliability. CNC-machined from solid billet aluminum, this adapter replaces the factory doghouse and poorly performing stock components to reduce oil blow-by, improve crankcase ventilation, and extend engine life.
Why Upgrade Your CCV System?
The stock crankcase ventilation system on 1994-2003 7.3L Powerstroke engines often fails prematurely and allows oil and fumes to contaminate your intake — leading to messy intercooler boots, reduced performance, and frequent maintenance. Proper crankcase ventilation is critical to managing blow-by gases that can rob power and increase oil consumption.
Unbeatable Features
-
CNC Machined Billet Aluminum — stronger and more precise than OEM
-
Optimized Airflow & Venting — engineered for smoother crankcase flow to minimize pressure build-up and emulsified oil return.
-
Direct OEM Replacement Fit — designed to bolt in where the factory CCV or doghouse mounts, compatible with Ford 7.3L systems.
-
Long-Lasting Corrosion Resistance — billet aluminum won’t warp or crack under repeated heat cycles like cheaper cast covers.
-
Easy Installation — straightforward swap that leverages existing mounting points.
For truck owners still running the aged OEM Ford CCV breather (F4TZ-6A665-A) on their Powerstroke — a part notorious for clogging and loss of performance — upgrading to a higher-flow billet aluminum solution is a smart performance move.
