I thought about a few things that made me question if they add horse power so i decided to ask. Also, I apologize for the questions, but I just wanted to get experienced answers or supported opinions.
Thanks in advance
1. throttle body spacers?
2. Different gaps on spark plugs, instead of noted specifications
3. lightweight pulleys
Also I wanted to know about performance of a chassis C-pillar bar; does it really make a difference
thanks again and reps will be given to any assistance![]()
