    I have to Say I am Sorry I Never Got back to write a Review. I remember waiting for Mac to get his First Batch of intercoolers made Back in 2003-04 i think it was. Well Long Story short. I bought the stage 1 then stage 2 for my Honda F12X. I would run half race gas and half 92 non Ethanol Gas and it made a Huge Difference. I had 2 2003 Honda F12X Skis with 19 Hours on them and i did every mod that Mac had to offer at that time. I remember he was in the process of doing Head work and cams and MSD on his own Aqua trax. That was a long while ago. But i Never did come back and write this Review. Long over Due Thank you Mac. These Kits Make all the difference. I could not have been happier. God Bless You.
