Excess electromagnetic interference?

Excess electromagnetic interference?
It seems my car emits a lot of electromagnetic interference. My radio sometimes has an RPM-based intereference through the antenna. My DIYPNP kept disconnecting randomly and during WOT so I replaced the USB cord with a serial extension cable which solved that. I also have a lot of noise in my CLT signal (the sensor is right next to the coils) and AFR (the signal cable goes above the transmission tunnel, so it's acting like an antenna) but not much noise in the MAT signal (which stays away from the coils).
Is this common? I'm thinking maybe the coils might be arcing to something but I don't want to replace it unless I'm sure that's the issue (I already replaced the spark plug wires for an unrelated reason) Is there any good way to shield the coils to send any EMI to a ground somewhere or is it likely something wrong with the coils?

I'm running RX-8 injectors and Bosch Platinum Spark Plugs. I don't know how to visually verify that these have resistors in them so I searched them and found a resistance of 5kohm. I'm assuming these classify as resistor plugs. I had never even heard of resistor-less plugs until trying to search out my problem.
