Who says horeypower has to be ugly?

Looks good.

Are the N/A and */C models the same one? Or are they different due to the N/A'* TB rake?

Notice the angled cut on my silicone reducer? I did that to make up for it, since my TB is straight. This was a perfect fit on Hector'* 99 SE. All I had to do was insert a piece of 3" PVC into the reducer, and cut on a bandsaw (PVC to keep the shape as it cut)

Well here'* what the autozone pipe is like in comparison.

The Straight section is much longer, by 4 inches i'd say, and the bend is slightly wider. This is more desireable if you have N/A , no extra washer bottle, or both. This will put it closer to the corner then the ADTR would on N/A.

The Autozone pipe is 3" mandrel bent aluminum. Has a grommet at the bend, and a small pipe sticking out, so you can either use your IAT in the hole, or run a tube to it. These would be good for Nitrous as well. The supplied Reducer, gets smaller where you'd hook it up, so it may work as a velocity stack. You could run the supplied reducer on the inside of the TB, and a 3" one on the outside of the TB and supplied reducer.

Otherwise they are pretty close. Either shimming like will wren did, or playing with the coupler will be needed for nearly all intakes, based on engines and options. Yes i noticed the coupler angle

I'll try to do this with my autozone pipe this afternoon after my class, so they can see what this new option is like. The biggest difference IMO is the powdercoat, and supplied reducer.

From those measurements it looks like that Center Line Radius is 5 inches. Will can you verify that?

Just a thought. The silicone coupler at the TB end gets larger to mount up, right? That will cause turbulance. If the pipe itself were larger, or it flared earlier, like halfway through the length of the pipe, air would be even more laminar.

Bill, just noticed the diet rootbeer can in the pic...WTF?

KIDS RULE! <-- It was on the ruler

Tell me some more about this Autozone pipe, BonnieMeMN, like what car is it for and stuff?

How much was the autozone pipe? Its interesting, as I might be making some intake upgrades. The FWI is in progress, I am almost done, I have test bends completed, I am using rubber though. It would need to be mandrel-bent piping to be any real use. I am still waiting for WIll'* idea before doing any actual cutting.

It'* the only thing at my local one, and it'* 3" aluminum mandrel bent steel. You'll need to get your own coupling solution, and filter. Made for a " 92-00 civic 94-00 integra" Orange and yellow packaging.
