I got the Dinan "horns" in today.

Hopefully I can install them soon with no loose fittings.

I installed them the other day. It was a pretty simple install, except here are a few things to note.

1. There are "squeeze" fittings. You just pinch them and pull.
2. If you remove the c clip on the stock turbo inlet before you try to take them off the turbo, your life will be much easier. Don't just pop it up.
3. The c clips on the other connector just needs to be popped up.



I think I can hear more turbo intake noise. I've got BMC air filters and I removed the charcoal filters. And luckily no check engine lights so far.

It took me probably 2 hours. I struggled to remove the stock inlets because of the c clip. I had to completely remove the clip and then they pulled right off. The instructions just mention popping it up, that didn't work for me.

Someone else can probably do it in an hour or less.

Same thing here. Everything went smoothly until I got to the first C clip. I pulled up a little, seemed like it stayed up but inlet wouldn't come off. Lots of swearing and didn't want to break anything so I called Dinan and they said grab it with pliers and pull it off. Sure enough, just pull hard enough. Passenger side was a breeze.

Did you dyno your car before and after to see if this is just for looks?

No. I'm not chasing numbers yet. I did it for more intake sound. I also removed the charcoal filters and installed BMC filters. Also, it does look nice.
