is anybody using these? are they worth the price? anybody done g-tech or dyno runs with them? what kind of gains are they worth?

 

i'v got a set on the GF's 03 Tiburon, and it definatly helped w/ rough ideling, though cant tell if it was all because of just the nology hotwire's, as i did a custom grounding kit and optima yellow top install at the same time. i feel that it was worth it though.
