2x Stainless Steel 2.7t EGT Sensor Port Block Off Bolts & Crush Washers

We have designed a much better and more versatile fitting for the EGT block off solution.  This design allows for three uses listed below:

1. Completely and cleanly remove your EGT sensors on your Audi B5 S4 by blocking off the port in your exhaust manifold.

2. Finish drilling thru the 3/16" hole (3mm depth left, drill diameter to suit probe diameter) and weld on an standard EGT specific bung to utilize cheaper and more robust sensors.  These can be logged on the stock ecu using a 0-5v output board and our data adder harness.

3. Finish drilling thru the 3/16" hole (3mm depth left) and weld on a 1/8" NPT bung.  Connect to a EMAP/Backpressure sensor canister with a 0-100/150 PSI sensor. This can be logged on the stock ecu using our data adder harness.  A thin open ended 17mm wrench will be used to tighten the bolt if this bung is welded on, easily available on Amazon.
