Q: Will this 3.5-inch intake manifold fit my 6.7 Cummins?
A: The listing identifies 2007-2018 Ram 2500 and 3500 trucks with the 6.7L Cummins. Match the engine, intake layout and existing charge pipe before ordering. A 2007 model-year badge alone does not establish the engine or connection compatibility.
Q: Is this Cummins intake manifold the same as a cold air intake?
A: No. This manifold sits on the pressurized intake side; a cold air intake serves a different part of the air path. The listed design uses a 3.5-inch inlet feeding two 3-inch tubes. It does not replace the complete air-filter system.
Q: What are the two NPT ports on manifold IM43201 for?
A: They provide threaded connection points for compatible accessories. The listing does not specify the thread sizes, supplied plugs or approved accessory applications. Confirm those details before buying fittings, and ensure unused ports are correctly sealed.
Q: Will the intake horn retain my grid heater and stock connections?
A: Grid-heater retention, dipstick clearance and compatibility with an aftermarket intake are not confirmed by the published specifications. Send photographs of your current installation and ask SPEtuner to verify those interfaces before disassembly.
Q: Does this 3.5-inch intake manifold guarantee lower EGT or better MPG?
A: No fixed improvement should be assumed for an individual truck. Exhaust gas temperature and fuel consumption depend on load, calibration, turbocharger condition and the complete air path. Compare before-and-after measurements under similar conditions rather than relying on a universal gain.
Q: What should my installer check after fitting the manifold?
A: Check the inlet connection, seals, mounting clearance and both accessory ports for leaks or contact. Use the correct application-specific fastener guidance. If response deteriorates after installation, check the installation before assuming the truck needs a different calibration.
