This page discusses air connections
The most frequently used sensor is the MPX4250AP (see WebShop). It mates with standard 6x4 (6mm external, 4 mm internal).
The higher temp, 180C capable tube is much more expensive than the 80C tube (7.8 Euro/m), but required for turbo systems.
There are 2 types of connectors:
- only bears pressure, not recommended for vacuum (useful for BoostControl)
- the one that bears vacuum, (this also bears pressure !!)
TODO: pictures
There is (currently) only a common connector-item in the WebShop, you can write the (reference name + size of) selected connector(s) in the order note.
| reference name (without size) | one side | other side | 3d side | note |
| VVV | vacuum-bearing | vacuum-bearing | vacuum-bearing | popular T for MAP connection |
| VIV | vacuum-bearing | vacuum-bearing | - | popular lengthening or through a plate (eg. frontplate) |
| PPP | pressure-bearing | pressure-bearing | pressure-bearing | boost side only !!! |
| MV | male thread | vacuum-bearing | - | can be bolted into a body |
| VV | vacuum-bearing | vacuum-bearing | - | lengthening |
- 6*4 mm VIV is the most popular to get MAP signal through the frontplate.
- 5*3 mm VIV will be popular with the 4bar pressure sensor
- the assymetric 5*3 mm on one side, 6*4 mm on other side VIV will be popular with the 4bar pressure sensor, if someone likes the thicker 6*4mm tube outside the ECM.
- 6*4 mm VVV is a popular T
AFAIK there is no clamp hose for the connection (eg. tube with MPX4250AP sensor) nor it is needed. (someone confirms?). It does not easily come off anyway.
