Remove Stock Intake: Disconnect hoses, unbolt stock intake manifold, and carefully lift it out
The first step in upgrading to a Banks Twin Ram intake is bidding farewell to your stock intake manifold. This component, while functional, often restricts airflow and limits your engine's potential. Removing it is a straightforward process, but it requires precision and care to avoid damaging surrounding components.
Begin by disconnecting the hoses attached to the stock intake. These hoses deliver air, coolant, and sometimes vacuum to various engine systems. Label each hose with its corresponding connection point to ensure a hassle-free reinstallation later. Use a flathead screwdriver or a hose removal tool to gently pry the hoses off their fittings, taking care not to damage the hoses or the fittings themselves.
With the hoses disconnected, it's time to unbolt the stock intake manifold. This typically involves removing a series of bolts securing the manifold to the cylinder head. Use a socket wrench or a ratchet with the appropriate socket size to loosen and remove these bolts. Keep track of the bolts and their locations, as some may be different lengths or have specific torque specifications. It's crucial to follow a systematic approach, removing bolts in a diagonal or crisscross pattern to prevent warping the manifold.
As the final bolts are removed, the stock intake manifold will be ready for extraction. This is where caution and patience are paramount. The manifold is often heavy and may have sharp edges, so wear gloves and use a helper if needed. Gently lift the manifold straight up, being mindful of any sensors, wiring, or other components that might be attached. Take note of the manifold's orientation and any gaskets or seals that may need to be transferred or replaced during the installation of the Banks Twin Ram intake.
Removing the stock intake is a delicate balance between force and finesse. While it's essential to apply enough force to loosen bolts and disconnect hoses, excessive force can lead to broken parts or damaged threads. Similarly, rushing through this step can result in overlooked connections or misplaced components. By taking your time, staying organized, and exercising caution, you'll ensure a smooth transition from the stock intake to the high-performance Banks Twin Ram system, setting the stage for a noticeable boost in engine power and efficiency.

Prepare New Intake: Inspect new intake, apply gaskets, and position it for installation
Before installing the Banks Twin Ram intake, meticulous preparation of the new component is crucial to ensure optimal performance and longevity. Begin by thoroughly inspecting the intake for any defects, such as cracks, warping, or manufacturing imperfections. Even minor flaws can compromise airflow or lead to leaks, undermining the system’s efficiency. Use a bright light and a magnifying glass if necessary to scrutinize every detail, paying particular attention to the mating surfaces and internal passages. This step is non-negotiable—a flawed intake will negate the benefits of the upgrade, no matter how precise the installation.
Once the intake passes inspection, the next critical step is gasket application. Clean both the intake’s mating surface and the corresponding engine surface with a degreaser to remove oil, dirt, or residue. Allow surfaces to dry completely before proceeding. Apply a thin, even coat of high-temperature silicone sealant to the gaskets, ensuring full coverage without excess. Over-application can lead to sealant entering the intake tract, while under-application risks leaks. Follow the manufacturer’s torque specifications for tightening bolts, as overtightening can crush gaskets, and undertightening can cause vacuum leaks.
Positioning the intake for installation requires precision and patience. Align the intake with the engine’s mounting points, ensuring all ports and connections match perfectly. If the intake feels resistant or misaligned, do not force it—recheck the orientation and surfaces for obstructions. Use a dry-fit approach first, placing the intake without final tightening to confirm alignment. This trial run allows you to identify potential issues, such as interference with other components or incorrect gasket seating, before committing to the final installation.
A practical tip for this stage is to use a marker or masking tape to label bolt holes or reference points on both the intake and engine. This visual guide simplifies alignment and reduces the risk of errors, especially in complex engine bays. Additionally, consider pre-threading bolts by hand to ensure they engage correctly, preventing cross-threading that could damage the intake or engine block. By treating this preparation phase with the same care as the installation itself, you lay the foundation for a seamless, trouble-free upgrade.

This step is the foundation for a secure and efficient installation, so take your time to get it right.
Bolting the intake in place requires a methodical approach to avoid uneven pressure or stripped threads. Start by hand-threading each bolt to ensure proper alignment, then use a torque wrench to tighten them in a crisscross pattern. Refer to the vehicle’s factory service manual for the recommended torque specifications, typically ranging from 15 to 25 foot-pounds depending on the engine model. Over-tightening can crack the manifold, while under-tightening risks leaks. If your vehicle has a cast iron block, consider using anti-seize compound on the bolt threads to prevent corrosion and ease future removal. This step is as much about patience as it is about precision.
Reconnecting hoses and sensors is where attention to detail becomes critical. Begin with the vacuum lines, ensuring each hose is securely attached to the correct port and free from cracks or kinks. Use a hose clamp tool to tighten clamps evenly, avoiding over-compression that could damage the hoses. Next, reattach the mass airflow sensor (MAF) and intake air temperature (IAT) sensor, ensuring their electrical connectors click audibly into place. Double-check that all sensors are oriented correctly, as improper installation can trigger check engine lights or disrupt engine performance. This phase is the bridge between mechanical assembly and electronic integration, demanding both care and thoroughness.
A practical tip for this stage is to label hoses and sensors before removal, especially if working on an older vehicle with faded markings. Use masking tape and a permanent marker to note each component’s location, saving time and confusion during reinstallation. Additionally, inspect all hoses and sensors for wear or degradation, replacing them if necessary to maintain optimal performance.
