ERZ HFC Performance

spearfish25 · 06-18-2010, 03:48 PM

I have my ERZ HFCs mounted to my Stillen exhaust without any problems. They've also withstood their first Chicago winter and still look new when I crawl under the car.

None of these HFC options are flawless. Google around for the Berk HFCs and you'll find a number of threads where the cores were burnt out or people have been throwing CELs. Given that fact, I couldn't justify buying Berks over the ERZs. Now that I've committed to the ERZs, I couldn't be more pleased. I saved some cash, got all the benefits of the HFC addition, and haven't thrown a CEL in 3,000mi. Could they fail or throw a CEL tomorrow? Sure. But so could a set of Stillens, Berks, or FIs. In the end, they are a great budget item which has no shortcomings that I can find thus far. If you want to feel like you bought the best, then you can always spend more money for a product that may ultimately perform exactly the same.

More money isnt always better, so I think the ERZs are a very product. Only time will tell on how the stand the test of time compared to the other companies out there.

One member here had them dynoed before and after ERZ installed and gained 12whp.

I believe I was either the first or second guy to install these on the site. I'll keep people posted if I ever run into an issue. So far, nadda.
