SPBREW Intake Manifold Kit for 6.7L Cummins (2007-2012)
Designed to precisely fit the 6.7L Cummins engines from 2007.5 to 2012, this SPBREW manifold kit focuses on restoring optimal airflow and engine performance. Not compatible with chassis cab versions. It features a double OEM-diameter intake to improve combustion efficiency compared to stock setups. Best for older 6.7L Cummins builds that require reliable intake replacement with improved flow. A caution: ensure you remove the P-clip when reinstalling the EGR pipe.
Key considerations
- Compatibility: 2007.5–2012 Ram 6.7L Cummins
- Performance aim: dual-diameter intake to enhance flow
- Installation note: EGR pipe P-clip removal required
SPBREW Intake Manifold Kit for 6.7L Cummins (2019-2026)
This SPBREW kit is precision-engineered for the 2019–2026 Ram 6.7L Cummins, offering a modern design to boost intake efficiency. It is not compatible with chassis cab versions. The kit promises enhanced driving experience, with an intake diameter twice that of OEM to improve combustion efficiency and overall engine performance. Choose this if you own a newer 6.7L Cummins and want a direct, performance-oriented upgrade with a focus on air delivery.
Best fit and caveat
- Best for: newer 6.7L Cummins engines seeking improved flow
- Caveat: not for chassis-cab configurations
SPBREW Intake Manifold Kit for 6.7L Cummins (Chassis-Cab 2019-2026)
Engineered specifically for Ram 3500/4500/5500 chassis-cab models, this SPBREW manifold addresses unique installation geometry while still delivering improved airflow. It pairs with grid heater and heating system features for optimized cold-weather performance. Best for chassis-cab operators who need a fit that accommodates longer engine bays and unique mounting points. A limitation: confirm chassis-cab compatibility before purchase.
Why choose this
- Best for: chassis-cab Ram configurations needing tailored intake geometry
- Consideration: verify exact mounting points and space constraints in your truck
loosoo Intake Manifold w/Actuator & Sensor (3.0L Diesel)
This Loosoo manifold includes both the actuator and sensor, simplifying installation for the 3.0L Ram Diesel and Grand Cherokee applications. It’s compatible with 2014–2019 Jeep Grand Cherokee and various Ram 1500 3.0L diesel variants. Best for those who want an actuator-integrated solution and want to reduce additional parts sourcing. Limitation: primarily for 3.0L diesel applications, not 5.7/6.4L gasoline engines.
5096255AA / 5096256AA Replacement Heater Blower Motor (Ram & Jeep)
While not a manifold, this blower motor is essential for maintaining cabin comfort on diesel-equipped Rams and Jeeps. Best for replacements or upgrades to ensure reliable HVAC performance, especially in cold climates. A potential limitation is that it is a generic heater blower solution, not a direct intake upgrade. Best used in tandem with manifold work where HVAC reliability supports overall vehicle performance.
Buying Guide
What should you check before buying a tunnel ram blower manifold or related intake kit?
- Engine compatibility: Confirm the exact engine model, year, and cab/chassis configuration to ensure a precise fit.
- Intake diameter and flow: Look for manifolds with a larger, balanced diameter to improve air delivery without causing fuel or timing issues.
- Integrated components: Some kits include sensors or actuators; verify compatibility with your vehicle’s electronics.
- Installation constraints: Some manifolds are designed for specific layouts (e.g., chassis-cab). Check clearance and mounting points.
- Warm-up performance: Grid heaters and heating systems can improve cold-start performance; consider whether you need them.
- External constraints: Some products are not compatible with all models (e.g., chassis-cab vs standard configurations). Double-check.
- Warranty and return policy: Ensure the supplier offers reasonable coverage and returns if the part doesn’t fit.
