Re: Do throttle body spacers really work?
They do work, you may feel a slight difference (or not). The theory behind them is that they atomize fuel molecules better than the stock t-bore and intake. I would opt for a larger t-bore and air intake system (K&N or similiar) then open up the exhaust to allow for the increase in air intake. You want a smooth flow of air in and exhaust out.
