MST and CTS have the best design. If you read the main thread on inlets, you will see that several were tested and those came out on top. https://f30.bimmerpost.com/forums/sh...1656337&page=8

Other ones are OK, and will be better than stock, but i would just wait for the "best" ones. Check various vendors to see if you can find one who has them.

The TIC does not fail like CP, but some people say the TIC swells/balloons when you get into higher boost levels. I can see why, it is quite thin and malleable. I didn't really notice a difference with the TIC change, more something i would just do while you are in there or if you have an issue.

Is this a good one? The only one I could find.

Ive never seen that one. All the major brands make one, its called TIC or turbo to intercooler pipe usually. ER, VRSF, FTP, etc should all have one.

It looks like an FTP. Do you think there is any value to wrap the TIC in reflective tape? And is it really a larger diameter compared to stock?

Reflective tape would not be desirable on a TIC pipe. The compressed air comes out of the turbo hot on its way to the intercooler to be cooled down. The stock plastic TIC isn't going to give off much heat. But an aluminum TIC is going to be radiating more heat which is desirable. It's best for the boosted air to lose as much heat as possible on its way to the engine.

I went back and forth in my head about wrapping the TIC before i installed it. I decided against it, based on the assumption that the air coming out of the turbo was hotter than the TIC and the surrounding air. So, wrapping it would actually be counter productive.

Also stock TIC isnt plastic, its rubber like a radiator hose but very thin (with metal ends).

Yeah, wrapping the TIC would just force more heat into the intercooler and make it work even harder. It's kind of the opposite situation from the downpipe. I purposely ceramic coated my Fabspeed downpipe because I didn't want it giving off more of that really high heat in the engine bay near the turbo. Ceramic coating it helped it to sweep more heat down and out through the exhaust system.

I considered using exhaust wrap on my DP but i read a bunch of threads that recommended against it, mostly because moisure could become trapped and make things rust. I would also be a little concerned about potentially overheating the cat on really long pulls or hard driving but not sure about that part. If i was catless i would have definitely wrapped it.

The owner who ceramic coated my catted downpipe said that when he coats catless downpipes he does them completely inside and out. The ceramic coating discourages the metal from being a heat sink and flows the heat right through to the exhaust.

I did my DP in black a few years ago to fly under the radar. Looks more like a shadow underneath and doesn't stand out. But they have a lot more ceramic coating colors now. I snapped a photo that I will attach.

I'll post a link in case someone reading this is interested. They do great work and people ship them parts to coat all the time. They are in PA.

I had a similar conversation with a race car builder about turbo blankets. He said the downside was that it would cover up a problem like a turbo oil leak until it was too late.

(Note: His opinion was that a turbo blanket wouldn't do much if anything on a street engine but that they had benefits on the track on very high horsepower race engines)

Well the benefit of wrapping/coating anything upstream of the turbo (and the turbo itself) is different than wrapping anything post-turbo.

The keeping in the heat pre-turbo increases the amount of energy that goes through the turbo, so more energy is spent spooling than "wasted" as heat. This is why heat wrapping a manifold for example can actually be a big benefit. Its the same reason why a lot of OEMs tuck the turbos into the V of engines now (audi i know for sure does, i think Merc does as well) - very short exhaust runner length from cylinder head to turbo and minimizes heat loss.

Wrapping post-turbo is more just for underhood heat control and doesnt actually affect the turbo itself.

The ceramic coating is nice and i might have done that had i planned ahead more before i installed my DP lol

Yes, thanks for pointing those out. My comment was aimed more at similarity of what you said about potentially trapping moisture & causing rust etc. How turbo blanket can coverup problems like oil leaks from being seen. I wasn't thinking big picture
