Warning to all of the earlier build 08/09 and some 10 owners:

If your car was fitted with the brass sensor, the connection at the rail differs from vehicles produced in the later model years.

The newer silver colored sensor has a different taper at the bottom near the threaded part where it secures to the rail.

For this reason it is ESSENTIAL to purchase the adapter for the rail which converts the rail into having a properly matched taper compatible with the newer sensor.

You can install the newer sensor in the older rail without the adapter, and as a result of this, I'm sure the necessity of having this adapter is commonly overlooked. Without being directly informed beforehand, it's very unlikely this would be caught during installation.

We also recommend replacing the o-ring there as well.

Hope this helps!
