Sorry, I'm stupid. What does this do for the car and what size motor?

Hi ffj. I believe the OP is actually discussing removing the "Air Intake Resonator", but the language translation is a bit off. Take a look here for more information: Ford Fusion intake resonator - Google Search

There are even a few threads right here on the Ford Fusion Club which are contained in the Google results above.

Essentially, the short story would be don't do it.

Good luck.

EDITED: I seem to have been the one with the language barrier.
The OP actually was discussing a "sound symposer" delete. Not the resonator delete.

why not? it just puts extra engine sound into the cabin.. i removed mine last week.. and nice and quite in the cabin.. and no harm to the engine or power

Hi alfaromeoguy. The links I provided explain why it would be better not to.

But we are all free to do with our cars as we like.

Good luck.

these links were for the 2012 and earier cars... mine is for the SOUND SYMPOSER not the ' resonator '

Hi alfaromeoguy. Okay..., now I understand better. So here are inks for others regarding the "Sound symposer" delete: Ford Fusion sound symposer - Google Search

Good luck.

after 1 week installed,, the engine feels much smoother, and power onset is smoother also.. the turbo is more linear build up

Hi alfaromeoguy. It is only a part of a sound synthesizer. It may be quieter inside without it, since it essentially eliminates the synthesized engine sounds. However, blocking/capping it does nothing for engine smoothness, power, performance, turbo performance etc. etc.

Good luck.

perhaps.. but my freinds whom have drivin the car also feel the same way.. anyway.. i am going back to my ecotec conversion into my 84 spider

Hi alfaromeoguy. I feel my car always runs, rides and feels better right after I wash it. And even better when I fully wash, wax and detail it. It feels great, but I know it is just a feeling.

Good luck with your 84 Spider!
