    This is the one Im looking at. I've done a search and have come to a few questions-

    1. Are TBI spacers worth it? Its 100 bucks or so, wondering if it adds any HP/increases fuel economy.

    2. Is their spacer really better than the ones avaliable from JEGS or Summit? The only real difference I can see is in the middle, it allows air to flow from one side to another.

    Thats all I can think of right now. Any help/comments/etc would be appreciated.

    I bought this one from ebay earlier this year. I don't know about a MPG increase, but I noticed a slight increase on bottom end torque. I don't know if the way the spacer you posted is made is better or not though. /forums/images/graemlins/thumb.gif

    I've got the injector spacer on order with them right now. I'm just waiting on my payment to go through with them. /forums/images/graemlins/thumb.gif
