Re: Sil2DrV6's 2002 Accord Coupe EX-L V6 Yep, that was my first word, when I first heard about their products. It's not heavy at all. (Say, about 9 oz.) It is indeed difficult to understand tho. Generally speaking, it's more like molecular science. Simply speaking, these things reduce "stress from mechanical fatigue / frictional loss in automobile components" (such as engine, transmission, suspension, etc.) and regain 'n restore a car's potential power / stability to the primary level. (I'm not really saying this directly to you, Brad → I'm just a firm believer of their products who bought this product just like regular ppl, not a "developer" who invented this damn thing. Lol) If you're interested, you can check out their website to get a lil idea. (The link below is the converted ver. by Google Translation in English, but I'm afraid it's not translated well.) http://translate.google.com/translate?hl=en&sl=ja&u=http://www.sev.info/auto/&prev=search Idk if you recall this, but I also made my own thread about one of their products back then, but the thread became messed up tho haha. More or less, one thing I can say is that, if this thing is just a piece of crap yet costing so much, ppl have sued them / became unpopular, and the company had already been going out of business way back in 1978. The brand is patented in major countries, and it's becoming popular and so big in Japan that their products are not only used among thousands of public users, but also in JGTC Super GT as well.
