Hello BB,

We've discussed this in another thread already, and yes, I also felt some improvement with the de-coned intake! I also felt better responsiveness, better running at cold start and much nicer sound!

But I'm surprised that you also found it more economical too! I haven't checked that (my tank is still half way) but I suspected it would be thirstier with this mod.

I was reading about high flow air filters like K&N etc, and found a thread where CJ says he uses the stock air filter and that he's not very found of these intake mods, he thinks the turbulence can confuse the MAF and the engine could be running rich, hence the more power.

My Q: does de-coning also contribute to turbulence and MAF misreading or it just increases air flow by less restriction? I ask that because I don't want the engine running rich, although I do like the way the car handles now.

Interesting...

I didn't understand maybe cause the word cone isn't familiar to me. Can anyone put a drawing or so. I am willing to try it on my 2.0Ts... i had to replace the MAF also, as someonte told me in this forum (thanks LeO), but this topic is fine also. Everything we can do to improve our Italian spirit is welcome.


The air cone is where the air filter is?

Thanks

The cone i refer to it that annoying "snout" that is attached to the cap of the air box & fits into the center hole of the air filer.

Removing is a matter of taking off the top cover & hose, undoing a large clip, pulling the cone upwards & re-assembling the parts again. 15 min's work.

Would a 2.5 v6 carbon fiber air intake fit a 2.0l T.S?

No, but there would be no point fitting it even if it did.

The Autodelta carbon intake tube only exists to get rid of the resonators that the V6 has in that area.

The TS already has a nice clean tube.
