Inlet Manifold Aluminum for Toyota 3K 4K 5K Engine 40mm DCOE Carburetor
Upgrade your engine’s airflow with this aluminum inlet manifold designed specifically for Toyota 3K, 4K, and 5K setups.
You will get smoother fuel delivery and precise air-fuel mixing when pairing it with a 40mm DCOE-style carburetor.
The three-layer aluminum construction dampens heat transfer while keeping the total weight down to just 0.7.
Front placement allows straight intake routing and reduces bend restrictions between the carburetor and cylinder head.
Benefits & Practical Tips
- Carb tuning: Match the manifold with a Weber or Dellorto unit to sharpen throttle transition during street cruising.
- Installation advice: Use fresh intake gaskets and high-temp sealant at the flange to eliminate vacuum leaks across the three layers.
- Clearance check: Verify hose routing length before bolting everything down, as the compact profile adapts cleanly to most vintage Toyota bays.
