3.5" Intake Manifold with Heating Element for Dodge Ram 2500/3500 6.7L Cummins 2007-2018
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.
