Got the new Helix throttle body spacer on my car last night. Install was a breeze. I think the hardest part of it was getting the left over gasket out. Its a 1" solid billet with a weird design and kinda has a subtle whistle when shifting. Another member has it on his car and he said its the best $90 he's ever spent. No dynos here and I don't even have a base to compare with but it feels to have a little more torque.
