Map Sensor:

At the other end of the manifold there is Honda MAP sensor fitment detail to allow the use of your standard or aftermarket MAP sensor to be fitted.


Multiple inputs/outputs:

As standard there are 5×5mm hose barbs.


Idle valve and Map sensor not included

Want this, but not quite like this?

A different size, a bore spacing we don’t list, a port shape to suit your head, a fitting somewhere else — we make these ourselves, so most of it is a drawing change rather than a new product. Tell us what you need and we’ll price it.

What’s included

In the price

  • One K20 vacuum manifold, so your MAP sensor and idle valve are kept when you fit ITBs
  • Honda K20 idle valve fitment at one end, taking a 19mm filter or hose to an airbox
  • Honda MAP sensor fitment at the other end
  • 5 × 5mm hose barbs

Not included

  • Idle valve and MAP sensor — the manifold is made to take the ones you already have
