Step 1: Preparation
- Ensure the engine is completely cool. Disconnect the negative battery terminals for safety. Locate the factory CCV box on the driver-side valve cover.
Step 2: Remove Factory CCV Components
- Disconnect the factory plastic vent lines from the CCV box.
- Unbolt the factory CCV box from the valve cover (keep the mounting area clean).
- Remove the factory intake resonance box or CCV cap if applicable to your model year.
Step 3: Install the CNC Integrated Filter
- Ensure the Viton O-ring is properly seated in the groove of the new CNC Integrated CCV Filter.
- Place the filter onto the valve cover.
- Secure it using the provided stainless steel bolts. Note: Use the optimized shorter bolt for the single-bolt engine cap piece as provided in the kit. Torque to factory specifications.
Step 4: Route the Hose
- Attach one end of the Reinforced Silicone Hose to the CCV filter using the provided AN-style fitting and clamp.
- Route the hose along the frame rail toward the rear of the truck.
- Pro Tip: Ensure the hose is secured away from moving parts (driveshaft) and extreme heat sources (DPF/Exhaust manifolds) using heavy-duty zip ties.
Step 5: Exhaust Integration (Optional but Recommended)
- Locate a suitable section on the rear exhaust tailpipe.
- Install the Rear Exhaust Integration Port. (If your exhaust is already prepped, simply thread the adapter in).
- Connect the end of the silicone hose to the port and secure it with a stainless steel clamp.
- If not integrating into the exhaust: Route the hose to a safe exit point at the rear and secure it.
Step 6: Final Inspection
- Double-check all clamps and bolts for tightness.
- Ensure there are no sharp kinks or pinches in the silicone hose.
- Reconnect the batteries and start the engine. Check for any air or oil leaks around the new filter.
