upgrade intake manifold?

[ch4d]

So i was curious what is out there for the 1999 tahoe for intake manifolds and after market fuel injection spiders.

the only thing ive really seen is the oem injection spider.. there are a few guys on the obs trucks that swap out their intake manifolds for the marine version which uses injectors.. but if i remember correctly it takes some modification to get it to work

the marine intake conversion is your only choice to up grade. It can be costly.
