A co-worker of mine from the dealership got a header for his civic hatch (92-95) so I asked him if he was going to use the old manifold. He said he was gonna throw it away so he let me have it for $0.

It looks just like the HF and STD manifold as far as I'm concerned. O2 Sensor goes in same spot. On the #4 runner, there is an "L" rather than a "3" or nothing at all. All the adapters i've seen have the exact same pattern. Like I said, it looks identical to an HF/STD.

Anyone ever used it for a T25 mani??

Let me know, thanks.

 

In short, it's the same.

 

Thats what I figured. The Inside diamete of the runners are: 1 1/4" x 1 1/2"

I'm sure it'll do fine, and for FREE, ya can't beat that.

Thanks for the re-assurance, no matter how educated your opinion is. just kiddin.
