I bought the obx from eBay really bad experience we lost like 37 hp at the dyno that's why I'm so worry about eBay parts.

Now THIS is what we like to hear. Well... typically we'd like to hear it helped. But actual people who tried em and have experience. Thanks for sharing but 37hp loss... damn..

Here is a comparison of what the intake manifold and throttlebody look like when we normally get them and what they look like when we're done.
