What I meant is the measurements of the inner diameter or the outer.

Want to know because I want to match them with ported TBs.

I don't know yet. I do know fever racing is uprev, nothing in my area is ecutek

2.5" ID. That I verified, I didn't verify OD.

Good, ID is what I wanted to know more

Thanks

For comparison, does anyone know what is the ID of the Stillen Gen 3 intake?

Update: Car is definitely performing different with intakes. Seems more ready to pick up and go. Very happy with mod, hoping to see dyno results

Pretty sure they're 2.5" as well.

Saw these a couple weeks ago they look very nice... interested

2.5" od pipe is 2.35" id. Same as oem.

How was cutting not required? I made my own CAI and used silicone and 100% had to cut the radiator support like all. Being 2.5" ID in the silicone to of course go around 2.5" OD pipe, it's even bigger then stillen going through there. Of course silicone can bend and stuff but you wouldn't want to. You'd be changing the shape of that section and changing the air flow through there. Not to mention the rubbing which I had and had to re cut the holes bigger.

At the moment the silicone tubes are bending a little through the holes. I am considering going back and cutting the holes to eliminate the bend.

Are you sure about that? I never heard of 2.65" OD aluminium pipe before.

I would. You have to remember the motor rocks a good bit. Every time you hit WOT and the motor rocks back and those tubes are being crushed in there, you're pushing and pulling on them and they will 100% rub through and be trashed.

Good point, will probably give that a look when I have a day off

It may be metric sized. 2.65" works out to 67.31mm. I've come across some real strange stuff at work.
