The Rennen Vacuum Manifold combines the vacuum signals from all six throttle bodies on a roller barrel ITB conversion into one stable source, since each throttle body alone only produces a small, rapidly fluctuating signal.

That stable vacuum feeds the MAP sensor, fuel pressure regulator, brake servo and idle control systems, so the ECU gets a consistent load reading instead of six pulsing ones.

Frequently asked

Which cars does the Vacuum Manifold fit?

This piece fits a wide range of models. Exact fitment for your car, year and options is confirmed on your free consult before anything is ordered.

What does the price include?

The delivered price includes the part from Fabspeed USA, freight to Australia, import costs and GST. Enter your postcode to refine delivery; the final figure is confirmed on consult.

How long until it arrives?

Every Fabspeed part is made in-house at Fabspeed USA with about a one-week production lead time, then allow another 3-4 days for delivery to Australia via UPS. That freight is already included in the price.

Who installs it?

Rennen Motorsport in Adelaide, or an authorised dealer near you. Fitting it yourself may also be an option depending on the part, so raise it on your consult; professional installation is quoted separately.

Is it covered by warranty?

Fabspeed products carry the manufacturer's warranty, supported locally through Rennen Plus as the Australian principal. See our returns policy.
