A friend of mine just got a 2000 Civic Si and it has a few half *** mods done to it and I'm in the process of sorting them out and putting it back to stock.

My question is about the Si intake,
Is the Si intake box any different than the standard Civic intake box? I would presume yes but it would be much easier to find if that were the case.
thanks.

 

are u talking about the box that has the air filter or the intake manifold

box that has the filter dont matter holds filter air goes in no differnce

 

The whole intake box assembly. Not the manifold.

 

intake box assembly should be the same

Should be or is?

 

It is the same as a 96-00 Civic Ex and Hx. I have seen Integra Ls ones work and I would think the air box would flow better. Stock ITR should work as well. If the car already has an intake on it and it is half way decent why not just leave it on?

 

So basically the air box is engine specific and not model specific? IE any car with VTEC in the same year range will have the right air box?

It has some POS ebay/unknown ram air intake on it. Which not only looks like **** but probably reduces HP in comparison to the engineer designed road tested factory intake. It also looks like its heat soaking as well.
The choice is clear.
