throttle body spacers?

[icr]

I did a search and nothing came up....anyone installed one of these things?

I'm looking for better MPG...don't care about power. Do these things increase gas mileage? Waste of money?

Exactly what Mafesto said. Never seen one or heard of one that was even as good as stock. Don't waste your time or money.

Smaller pilot jets, Tempaflow, Ataac.

I used an Airaid throttle body spacer with their air intake kit. It did increase my fuel mileage a little bit, but it also set off my check engine light. The dealer said it was a lean code due to the kit. Took it off and no check engine light.
