Throttle Body Inlet Pipe (a.k.a., Upper Charge Pipe) Replacement?

[blueroadster]

I am looking to replace the cast aluminum OEM upper charge pipe to get rid of another unnecessary heat sink under the hood. Any aftermarket suggestions for that specific part by itself?

I've already replaced the 5.6 pound cast aluminum OEM turbo inlet pipe with a carbon fiber Eventuri one that weighs 0.8 pounds as mentioned in this thread.

Bump...Part in question is number 8 in the below diagram:

Is anyone aware of any aftermarket upgrades for this particular part? Ideally, I am looking for one made from carbon fiber that either connects directly to the 66mm OEM throttle body or supports connecting to a larger 74mm throttle body.

Never seen a carbon one before, but HPS does make a charge pipe kit with all aluminum tubing, so there's no cast aluminum like other kits.

Cool and thanks. I am curious as to what options are available if one were to upgrade to an oversized or Bosch 74mm throttle body.

It would probably still be the same options, its usually the inner bore and the butterfly flap of the throttle body that's larger. The outside dimensions usually stay the same so you can still use stock or aftermarket charge pipes of the same size.

Stay with the OEM throttle body. It's a turbo charged car, it gets its air by pressure not so much free flow. I did a larger tb on my car for 6months and my fuel mileage went down by 4mpg with no gain in HP. Also it was very annoying to just cruise on the road, because the slightest touch of the pedal would make it accelerate instead of maintaining a speed.

I also did charge pipes. The aluminum pipe absorbs heat so I wrapped the upper pipe in thermal wrap. Slightly better response and midrange HP. There is also a slight increase in turbo noise (throaty).
