Engine Parts

Genuine OEM Engine Parts

A sticking throttle valve, a failed oil pressure sensor, or a clogged crankcase ventilation separator can each bring an engine to a crawl — or shut it down entirely. Because these components manage airflow, fuel delivery, lubrication, and combustion together, a wrong or generic replacement often leads to recurring fault codes, reduced performance, or premature wear on other parts. That's why every component in this collection is genuine OEM, matched to the manufacturer's original part number.

What's in this category

This collection covers the core engine components for diesel and gas engines, including:

  • Injector harnesses — wiring connections between the ECM and fuel injectors
  • Control valve thermostats — regulate coolant flow through the cooling system
  • Air intake connections & tubes — deliver clean air to the engine
  • Inlet throttle valve kits & throttle valve bodies — control airflow into the combustion chamber
  • Crankcase oil ventilation separators — remove oil from blow-by gases before they re-enter the intake
  • Intake manifold covers — protect and seal the manifold assembly
  • Engine oil pressure sensors — monitor oil pressure and alert the ECM to low-pressure conditions
  • Engine oil pump kits — circulate oil throughout the engine for proper lubrication
  • Camshaft covers — seal and protect the camshaft and valvetrain components

Brands we cover

This collection includes genuine OEM engine parts for Cummins, Volvo, International, Mack, Mopar, GM and more.

Why order your engine parts here

  • Genuine OEM only — every part is matched to the manufacturer's original part number, not a generic equivalent
  • Built for accurate fitment — listings include the exact OEM number so you can verify the right part before you buy
  • Fast turnaround — ships quickly to minimize downtime and keep your engine running right

FAQ

What does a crankcase oil ventilation separator do? It removes oil droplets from crankcase gases (blow-by) before they return to the intake, preventing oil buildup in the intake manifold and turbocharger.

Signs of a failing throttle valve body? Rough idle, hesitation under acceleration, a check engine light related to airflow or throttle position, or an engine that won't reach full power.

What happens if an oil pressure sensor fails? It can trigger inaccurate dash readings or false low-pressure warnings — and may mask an actual lubrication problem.

Genuine OEM or aftermarket? All parts here are genuine OEM — no generic substitutes.

How do I find the right part? Match the OEM number on your old component or check your service manual, then search that number above.
