Air Intake - quality and affordable price page 1 of 2

Air Intake Components for Diesel Engines and Heavy-Duty Trucks

Air intake parts play a critical role in supplying clean, pressurized air to diesel engines, ensuring proper combustion, fuel efficiency, and smooth acceleration under all load conditions. Our selection of air intake elbows, intake plenums, grid heaters, turbocharger air transfer pipes, and manifold adapters covers a wide range of engines including Cummins ISB, ISL, ISX15, QSB, QSX; Caterpillar C9, C13, C15; Detroit Diesel DD13, DD15; Volvo D12, D13; Mercedes MBE4000 and other popular heavy-duty platforms.

The importance of a proper air intake system

A well-maintained diesel engine air intake system ensures the correct volume of filtered air enters the engine, improving throttle response, reducing turbo lag, and preventing contaminants from entering the cylinders. Damaged elbows, cracked intake manifolds, or worn adapters can cause air leaks, loss of boost pressure, poor fuel economy, and increased emissions – issues especially notable for long-haul trucks, commercial fleets, and high-load vocational equipment.

When choosing replacement air intake components, pay attention to:

• compatibility with engine model and year (e.g., Cummins ISB 6.7, DD15, Volvo D12),
• OEM reference number and flange configuration,
• airflow capacity and heat-resistance rating,
• type of connection: plenum, elbow, grid heater, or manifold.

Reliable airflow parts for consistent performance

Our catalog includes both new and OEM-spec parts designed to withstand heavy vibration, thermal changes, and high boost pressure from modern turbocharged diesel engines. Whether you’re replacing a cracked air transfer intake elbow, upgrading a turbo air inlet pipe, or restoring the entire air intake manifold assembly, each component is built to maintain stable airflow and support long-term engine reliability.
