"It won't magically add 100hp to your car's output and it won't grow hair back."
I feel a need to step in here. When I had my SVX I had this done, made a HUGE difference in the performance of the car and I would recommend anyone try this. My mechanic who is also a close friend did it for me and said it was fairly easy to do and he also commented on the improvement.
Now, 3 years later some of my lost hair is beginning to grow back, coincidence? I think not.
