It's not something you can really feel, but...
This part shuts off the introduction of secondary air.
The installation itself is easy, but it is quite Large strange to that point.
I have to remove the tank, air cleaner box and flip the rubber cover for heat shield.
The back side is threaded through the throttle body, so you can flip it from the front side.
In order to do so, the Ignition and Sensor connectors connected to the cylinder head must be disconnected.
If you remove the fixed Bolt of Radiator and set it to Free, you can flip the Cover.
Rubber cover has to be cured Throttle etc. because of the sand and dust on it.
The product itself is Cut-out of Aluminum, and the texture is high.
After all, it is expensive for the parts and a bit heavy compared to OEM.
It's a shame because weight reduction is a very simple task and I would like to gain more value with external parts like this. (Although it is lighter in terms of the whole system)
As for the effect, in the case of Racing Exhaust System of AKRAPOVIC
The bobbing that happens just before I fully revert the Axel has improved.
It's not completely fixed. It seems to have an effect on After Fire of a common popping sound, but it doesn't know because it doesn't have it originally. Probably, it will be effective for that one.
As for the OEM, there is no change at all.
I've heard that it weakens the embrasure, but no there either.
(I'm not sure about Mechanism on this one)
