What's a NA spider intake worth? The whole thing, wiring harness and TB...everything.

What about with no injectors?

probably $50 max. The only true answer is "whatever someone would pay for it" which isn't helpful, but they're kind of a medium to low-demand item, not like LSDs or rear disc setups. I sold a turbo spider setup a while ago. I think it was to Suberdave? I think I was asking more than $50 but it took a while to sell it. Including the injectors might help but of course someone buying this is putting it on another MPFI which already has injectors....

I paid $25 bucks for a complete one from a junkyard in Denver. Then I modified it to work with my turbo.
