Description

Unlock maximum performance for your 6.7L Dodge Ram without sacrificing reliability. Stock intake manifolds restrict airflow, and most aftermarket grid heater delete kits hurt cold-weather starting. The SPETUNER 3.5" Performance Intake Manifold delivers the best of both worlds: peak power and all-season dependability for serious Ram owners.

Our integrated high-efficiency heating element in a high-flow T-304 stainless steel manifold eliminates the trade-off between performance and cold starts. Boost airflow to gain faster turbo spool, more horsepower, increased torque, and sharper throttle response – all while ensuring reliable starts in cold weather.

Note: When installing with a Grid Heater Delete Plate, an IAT Sensor Extension Harness is required. Factory wiring is too short for the new sensor position – add the harness for a perfect plug-and-play fit.

Key Features

• Integrated High-Efficiency Heating Element
  Ensures fast, reliable cold-weather starts, reduces engine wear, and eliminates excessive white smoke. No more choosing between performance and cold-start reliability.
• 3.5" High-Flow Design
  Mandrel-bent T-304 stainless steel boosts airflow vs. stock, delivering quicker turbo spool, lower EGTs, and measurable gains in horsepower and torque.
  
• Premium Durability & Construction
  T-304 stainless steel for strength, corrosion resistance, and heat dissipation. Precision TIG welding ensures leak-proof performance under extreme conditions.
  
• Direct Bolt-On Installation
  Uses factory mounting points for easy fitment. Includes dual NPT ports for boost gauges, sensors, or water-methanol injection systems.

Eliminate Grid Heater Bolt Failure Risk

The 6.7L Dodge Ram's factory grid heater has a well-known flaw: retaining bolts/nuts fail, break off, and fall into the intake – causing catastrophic engine damage. Our manifold removes this weak point with a bolt-free heating coil, protecting your engine investment for good.

High-Efficiency Heating Technology

Replace the restrictive, failure-prone factory grid heater with our advanced integrated heating coil. Enjoy effortless cold starts in any climate while removing airflow restrictions for maximum performance gains.

Optimized Cylinder Airflow

Stock intake manifolds cause uneven air distribution across cylinders, robbing power and efficiency. Our high-flow plenum delivers uniform, pressurized airflow to every cylinder – unlocking smoother operation, a wider powerband, and maximum combustion efficiency.

Reduce Carbon Deposit Buildup

EGR-related carbon buildup clogs stock intake passages, reducing power, throttle response, and fuel economy. Our smooth-wall stainless steel manifold minimizes carbon accumulation, keeping your engine breathing clean and performing at peak levels long-term.

FAQ

Q1: Will this intake manifold fit my 2007-2018 Dodge Ram 6.7L Cummins?

A1: Yes. It is designed for 2007-2018 Dodge Ram 2500 and 3500 trucks with the 6.7L Cummins diesel engine. It does not fit Cab & Chassis models.

Q2: What is the main benefit of the integrated heating element?

A2: The integrated heating element helps warm incoming air for cold starts while allowing the manifold to use a less restrictive high-flow design.

Q3: Does this replace the factory grid heater setup?

A3: This manifold is designed as a high-flow upgrade with an integrated heating element, helping remove the factory grid heater weak point from the intake path while maintaining cold-start support.

Q4: Do I need the IAT Sensor Extension Harness?

A4: If you install the manifold with a Grid Heater Delete Plate, the IAT Sensor Extension Harness is required because the original wiring may not reach the new sensor location.

Q5: Can I use this intake manifold for towing?

A5: Yes. It is a good fit for towing and hauling applications where better airflow, stronger durability, and dependable cold-start behavior are important.

Q6: Will this work with stock intercooler piping?

A6: This manifold is designed for straightforward installation using factory mounting points. Always confirm your current intercooler piping, sensors, and supporting parts before installation.

Q7: Is tuning required?

A7: Tuning is not always required for installation, but a proper tune and supporting modifications may help maximize performance gains from increased airflow.

Q8: What should I check before ordering?

A8: Confirm that your truck is a 2007-2018 Dodge Ram 2500 or 3500 with a 6.7L Cummins diesel engine, and make sure it is not a Cab & Chassis model.

Why Upgrade 6.7 Cummins Intake Manifold?

The factory intake manifold and grid heater setup can restrict airflow, affect throttle response, and create a known weak point inside the intake path. This 3.5" high-flow manifold is designed to give your 2007-2018 6.7L Cummins a smoother airflow path while keeping the cold-start benefits of an intake heating system.

• Improves airflow compared with the restrictive factory intake path
• Helps support quicker turbo spool and better throttle response
• Helps lower exhaust gas temperature under demanding use
• Retains cold-start support with an integrated heating element
• Removes the factory grid heater bolt/nut failure concern from the intake path
• Adds auxiliary ports for sensors, boost gauges, or water-methanol injection

Who Needs This Product?

• 2007-2018 Dodge Ram 2500/3500 6.7L Cummins owners upgrading the factory intake manifold
• Truck owners who tow trailers, haul heavy loads, or use their Cummins for work
• Drivers in cold climates who still need dependable cold-start support
• Performance-focused users who want better airflow without removing intake heat support
• Owners are concerned about the factory grid heater bolt failure
