Additionally, Accel sells a couple different versions of their cap and rotor.
The first version is labeled as their "Heavy Duty" version that are gray in color with brass inserts.
The second version is labeled as their "High Performance" version that are tan in color also with brass inserts. This is the one we've had on the car for the better part of a decade.

So now I have more questions:
*Are the tan Accel cap and rotor we currently have installed also illegal because the are labeled as their "High Performance" versions?
*Are even the gray "Heavy Duty" labeled Accel cap and rotor also illegal because they also have brass inserts while other "OEM replacement" cap and rotors under the Duralast, Valuecraft, MasterPro, and even the Motorcraft versions do not have brass inserts?
