Im planning on pulling the trigger on an intake this week but im having trouble deciding between the two. I will be using the intake on the 93 stock tune for a couple months untill i get a protune. Both companys claim that its safe to use on the stock 93 tune, and ive seen that people have had no issues thus far. I have not yet heard the ETS,intake setup yet and id like to hear some feedback if anyone has one. I was going to go mishimoto because more people have it and theres no problems with it sofar. Then i saw that the ETS uses a bigger cone filter on their setup and im wondering if that would increase the sound/power?
