An EGT probe is a probe that is installed in the exhaust gasses to monitor exhaust temps. Usually people have this if they have their cars modded to watch that they don't over temp their turbos.

You would want the first one you listed.

Will the block off plate cause a fault code?

Most likely yes as the EGR lowers the MAF reading as it introduces exhaust gases after the MAF. Of course a tune can eliminate the fault code. I have RC4 and the block off plate + EGT as I am tuned up to 150 hp.

....except that the intake opening is turned the wrong way. You can purchase a PD130 or 150 intake that will turn in the correct direction.

Stick a screw in the vac line. Better yet, do so just a few inches from the N18 valve.

Better yet? Leave the EGR functioning. With today's ULSD fuel, you may never have to clean it again.

Just disconnecting the vacuum line and plugging it will accomplish the same thing. Leave the cooler connected to help your car warm faster in winter.
