aFe BladeRunner Dodge Ram 5.9L 12-Valve Intake Manifold 1994–1998

BladeRunner charged-air intake inlet for the exact engine

The aFe 46-10051 is the BladeRunner charged-air intake inlet for 1994–1998 Dodge Ram 2500/3500 trucks with the 5.9L Cummins diesel 12-valve engine. It is cast A356-T6 aluminum with Multiple Directional Vane airflow passages and an internal mounting-bolt arrangement. It replaces the inlet above the retained grid heater, rather than supplying an exhaust header, tailpipe or complete cylinder-head runner manifold.

Key Features

• Correct intake-side component classification and cast aluminum construction replace incorrect exhaust/header and stainless tubing claims.
• Manufacturer overview reports 32.9% more flow and 17 hp / 50 lb-ft in its test. These are comparison results, not guaranteed vehicle gains.
• Current primary describes up to five auxiliary port pads; this does not mean five supplied threaded sensor connections. The exact kit includes two 1/8 NPT and two top 3/8 NPT plugs; no sensors or injection system are included.
• Retains the factory air-grid heater with new gaskets above/below it; the kit is not a heater-delete or EGR-conversion instruction.
• Exact 12-valve and EGR exclusion govern, including the shared 1998 year boundary.

Fitment

46-10051: The exact current page and manual identify 1994–1998 Dodge Ram 2500/3500 5.9L Cummins diesel. The exact manual specifically says 12-valve, and the current primary excludes vehicles equipped with EGR. Actual engine configuration governs the shared 1998 model year.

Specifications

What's Included

• One cast A356-T6 aluminum charged-air intake inlet/manifold; this is not an exhaust header or complete cylinder-head intake runner assembly.

Frequently Asked Questions

A charged-air intake inlet/manifold for the exact stated Dodge Ram 5.9L diesel application; it is not an exhaust manifold or complete intake runner assembly.

No. The exact instructions retain it and replace the gaskets above and below it. Keep debris out of the open intake and verify the actual heater/manifold interface.

The exact current page and manual identify 1994–1998 Dodge Ram 2500/3500 5.9L Cummins diesel. The exact manual specifically says 12-valve, and the current primary excludes vehicles equipped with EGR. Actual engine configuration governs the shared 1998 model year.

No. Up to five auxiliary pads in overview copy is not five verified tapped accessory ports. The exact parts list supplies two 1/8 NPT and two top 3/8 NPT plugs, with no sensors or injection system.

Two long and two short M8 manifold bolts, two gaskets, four M8 washers, M8 dipstick screw and a separate M8 flange screw.

The exact May2009 manual specifies 18 ft-lb for four manifold mounting screws, the M8 flange screw in the intake plate and the two top 3/8 NPT plugs. The intercooler coupling clamp is 71 in-lb. It says to check screws periodically, without a mileage interval or numerical dipstick-screw value.

No. The manufacturer's individual test figures do not guarantee a gain on every engine or establish a boost setting, working-pressure rating or permission to change emissions equipment.

The current primary cites CARB EO D-550-10 for the exact part application. The official indexed application table identifies this part for 1994–1998 Dodge 5.9L diesel pickups; the exact manual's 1994–1998 and engine restrictions still apply. Match the actual configuration and EO identification, without extending the exemption to altered tuning, other engines or EGR equipment.

Installation Instructions

1. Read the exact manufacturer instructions for 46-10051, verify the actual engine, supplied parts and every unresolved source conflict before disassembly.
2. Allow the engine to cool, secure the vehicle and follow the exact application-specific manual. Observe the original vehicle's service precautions before working around the retained air-grid heater.
3. Release the original intercooler coupling clamp and dipstick mounting screw. Remove the five original manifold screws as illustrated.
4. Remove the original manifold carefully, cover the exposed heater opening with a clean rag and prevent debris from entering the engine. Remove the old upper/lower heater gaskets and clean the mating surfaces.
5. Fit the 1/8 NPT plugs with the specified treatment. Place the two shorter M8 mounting screws and their washers through the inside flange, with the two longer M8 screws and washers at the outer bosses. Apply supplied threadlocker to the mounting screws.
6. Remove the temporary protective rag before assembly. Install both new gaskets around the retained heater and guide the manifold and bolts through the gaskets/heater without shifting the seals. Engage the original coupling and start the bolts by hand.
7. Fit the listed M8 flange screw at the intake plate and torque it to 18 ft-lb. Torque the four manifold mounting screws to 18 ft-lb and the original coupling clamp to 71 in-lb, as specified.
8. Install the two top 3/8 NPT plugs with the instructed threadlocker at 18 ft-lb and restore the dipstick with the listed socket screw. Follow applicable EO identification instructions and check mounting screws periodically; no numerical dipstick-screw value or mileage interval is given.

46-10051: inspect every connection and resolve the documented kit discrepancies before operation.
