no the plates are 304 stainless, I did not see any gains on hho alone, matter of fact my mileage got worse, i use an ecu genie, which controls the ECT sensor, IAT sensor, the MAF sensor, and both pre-cat o2 sensors, thats how i get the gains. it keeps all the sensors giving around the same readings so the computer doesnt think that anything is rong, and does not try to adapt to it. works great, everyone should have one.
