  • HKS Super Sequential BOV kit
  • Socket set
  • Wrenches
  • Phillips screwdriver
  • Flathead screwdriver
  • Vacuum line (if necessary)

Preparation Steps

Before you begin the installation, it’s important to prepare your workspace and vehicle. Follow these steps to ensure a smooth process:

Removing the Stock BOV

The first major step is to remove the stock BOV from your vehicle. Here’s how to do it:

  • Locate the stock BOV on the intake manifold.
  • Disconnect any vacuum lines attached to the stock BOV.
  • Remove the bolts securing the BOV using a socket wrench.
  • Carefully lift the stock BOV off the manifold and set it aside.

Installing the HKS Super Sequential BOV

Now that the stock BOV is removed, you can install the HKS Super Sequential BOV. Follow these steps:

  • Position the HKS BOV onto the intake manifold in the same location as the stock BOV.
  • Align the bolt holes and secure the BOV using the bolts provided in the kit.
  • Tighten the bolts to the manufacturer’s specifications using a torque wrench.
  • If necessary, attach any new vacuum lines as specified in the HKS installation manual.

Connecting the Vacuum Lines

Properly connecting the vacuum lines is crucial for the functionality of the BOV. Here’s how to do it:

  • Identify the vacuum source on the intake manifold.
  • Cut the vacuum line to the appropriate length if needed.
  • Attach one end of the vacuum line to the BOV and the other end to the vacuum source.
  • Secure both ends with hose clamps to prevent leaks.

Finalizing the Installation

With the BOV installed and vacuum lines connected, you can finalize the installation:

  • Recheck all connections and tighten any loose bolts or clamps.
  • Reconnect the negative battery terminal.
  • Start the engine and allow it to idle for a few minutes.
  • Check for any leaks around the BOV and vacuum lines.
