This one is a knock-off, the Top Fuel intake looks like a carbon fiber muffler with a right angle bend, and then a chrome pipe. Except Top Fuel puts the canister section by the battery, not by the throttle body. The Type S also flares by the battery and gets narrow by the TB, so I am not really sure if this Ebay design is any good.
Here is a picture:
With a review like this you know it's good:
Using air pulsation with the internal constitution which even crystal of aeromechanics can be said, while from the air cleaner, always compressing the air to the chamber, it fills up.
Also, you can buy the authentic Top Fuel Power Chamber intake for the Prelude. I found it listed on a US based website, it's around $240 (too rich for my blood).
