Spring is almost hear and looking forward to spend some money I have been saving over the winter. Wanting to improve the whole air intake. Question about throttle body spacers. Are all brands the same or is one better than the other, or not worth the time & $$. For under $100 seems like it would be a good cheap mod if it does make a difference. Already decided on the CAI I want & changing out the throttle body itself. Any insight would be great.
