• Gives the gauge a dedicated intake feed. The adapter taps the intake so the gauge reads boost from the engine rather than from a spliced hose.
• Leak-free install. Supplied with stainless bolts and a new O-ring.
• Direct fit. No cutting, no welding, no modifications to the factory hardware.
• Billet anodised aluminium. Available in several HPD colours.
• It does not change how the engine runs. It is a mounting point for a gauge. No tuning and no extra parts are needed to fit it, and it makes no power on its own.

• Holden Rodeo RA7. 4JJ1.
• Holden Colorado RC. 4JJ1.
• Isuzu D-MAX. 4JJ1, 2006 to 2016, pre-DPF.
• Isuzu MU-X. 4JJ1, 2012 to 2016, pre-DPF.

• One HPD billet boost gauge adapter in your choice of anodised colour.
• Stainless bolts.
• New O-ring.

The gauge, the gauge line and the fitting that screws into the adapter are not included. Buy them to suit your gauge.

• Direct bolt-in. No tuning, no additional parts required to fit the adapter itself.
• Fit it to a cold engine and check the O-ring is seated before you do the bolts up.
• Check for leaks once it is running. A boost leak at the gauge take-off will read as low boost and drive you mad chasing it elsewhere.

Confirm the gauge port thread before you buy your fitting. This listing does not publish a thread size for the gauge port, and we are not going to guess one for you. Message us with the gauge and fitting you plan to run and we will confirm what the adapter takes before you order, so you are not left with a fitting that will not screw in.

Some colour options sell out quickly. If the one you want is not available when your order comes through, we will contact you with the alternatives or order it in specially for you.

Installation is a DIY job and is done at your own risk. If you are not confident pulling the intake apart and sealing it back up, have it fitted.

Q: Will this make more power?

A: No. It is a take-off point for a gauge. It tells you what the engine is doing, it does not change it.

Q: Do I need a tune to fit it?

A: No. It is a direct bolt-in with no tuning and no extra parts required.

Q: Does it come with a gauge?

A: No. Adapter, stainless bolts and O-ring only.

Q: What thread does the gauge line screw into?

A: We do not publish a thread size for it on this listing. Message us before you order your fitting and we will confirm it rather than have you guess.

Q: Will it fit a DPF model D-MAX or MU-X?

A: The fitment above is pre-DPF only. Send us your build details before ordering if you are on a later model.
