Cummins KTA38 Diesel Engine Parts Tube Air Inlet 3630534

Part Number: 3630534
Standard Name: TUBE, AIR INLET Transition Steel Tube
Outer Packaging Dimensions: 44cm × 30cm × 18cm
Net Weight per Piece: 2.971 KG
Brand: Cummins (Chongqing Cummins CCEC Original Part)
Material: 1.5mm thick aluminum-plated steel plate, surface rust-proof coating, suitable for high-temperature boosted air intake conditions

Replacement of Fault Characteristics:
1. Steel pipe corrosion perforation, weld seam cracking, boost air leakage, engine power loss, and soaring fuel consumption;

2. Flange sealing surface deformation, air leakage, air filter alarm, and black exhaust smoke;

3. Long-term vibration fatigue fracture, turbocharger pressure not rising, and reduced speed under heavy load.

Structural Integrity

- Aluminized Steel Construction: Combines heat resistance (up to 1,200°F/649°C) with corrosion protection, doubling the lifespan of generic steel tubes.

- Reinforced Bends: Precision-molded 90° and 45° bends minimize airflow turbulence, improving volumetric efficiency by 8%.

- OE-Level Fit: Direct bolt-on replacement for KTA38-G5 engines (2015+ models)-no modifications required.

Airflow Optimization

- Smooth Inner Surface: Micro-polished bore (0.8 µm Ra) reduces air resistance by 15%, enhancing turbocharger response.

- Integrated Clamps: Pre-installed T-bolt clamps ensure leak-free connections at 12 PSI (0.83 bar) boost pressure.

Product Function
Connects the turbocharger outlet to the intake manifold, delivering high-temperature boosted air;
The bent buffer structure absorbs engine vibrations, preventing pipe cracking and air leakage;
The low-resistance inner wall design ensures intake airflow, preventing power loss and excessive black smoke;
Double-layer sealed flange positions, combined with composite sealing gaskets, completely prevent boosted air leakage.
