▷ReviewːI got a package that seemed like it's been traveling for a while. When I opened it, I found these two O2 bands inside. They look really cute, like rubber pads or something. The instructions said to stick these soft things to the engine intake, so I tried them out on my old buddy's car. I've done a lot of tinkering with my car, so I wasn't too worried about it. But what the heck are these things? They're just rubber pads, but I can definitely feel the gas pedal's sensitivity has improved and there's more power. I went back to the site for more info, but I still don't get it. One thing's for sure though, my car's a lot stronger now. I don't know what those Koreans are doing, but they're impressive folks. I just clicked the apply button and got these rubber pads for free. It's been a cool experience. Here's hoping everyone has success.
