I installed this POSH AIS Cancel Plate on my Yamaha SR400 because I had an after market exhaust. The AIS (Air Induction System) causes air to be pumped into the exhaust system to detonate unused carbon emissions in the OEM exhaust's catalytic converter. Since I already replaced my OEM exhaust with an aftermarket slip on exhaust, I was getting a lot of unwanted "popping" noises whenever I was decelerating the bike or going down a steep hill. This AIS Cancel Plate allowed me to plug the AIS hole in the engine block and remove the AIS unit all together. I now have a cleaner looking bike without all the pipes, cables and AIS unit. Some people say this will also result in increased throttle response and of course a little lesser weight on the bike. Even though the packaging says that this POSH AIS Cancel Plate is for Carb SR400 only, I was able to successfully install it on my 2018 SR400 FI and the check engine light did not come on

Get this with any aftermarket exhaust!
POSH AIS Cancel plate is a must if using any aftermarket exhaust. I bought this to go with a Peyton Place Stainless/Norton type slip on (part number SP-055) on my 2014 SR400 FI. Very easy install, much cleaner look without the the AIS and eliminates all deceleration popping from the aftermarket exhaust. This product description says non-applicable to FI vehicles but have installed fine on my fuel injected SR400 - note that the rubber bung included is too small to go over the airbox hole left behind but is a perfect fit to be inserted the other way around the plug the hole tightly.

Ho utilizzato il kit per eliminare il filtro AIS e mi è sembrato funzionale, ho avuto solo qualche problema con la parte in gomma che doveva fungere da tappo perchè le dimensioni non erano corrette probabilmente perche' le versioni dell'air box sono cambiate durante gli anni di produzione. Tuttavia sono stato in grado, con modifiche lievi, di utilizzarlo comunque.I used the kit to remove the AIS filter and it seemed functional, I only had some problem with the rubber part that was supposed to act as a cap because the dimensions were not correct, probably because the versions of the air box have changed over the years of production. However, I was able to use it with slight modifications. (Translated by google translation)

The word AISCancellation is a GunDam-like feeling ...
If you look at the word AISCancellation somehow Parenthesis is good ....
Well, the subject - After replacing the Exhaust System AfterFire sounds panpan, it is thought that this will be done by exchanging the Exhaust System. (I exchanged the past two Exhaust Systems, but after all it was out. )
Even if Jete Ing's adjustment is done, the frequency of AfterFire A will be a little better, so I tried Cancellation of AIS with a tough stance.
It definitely disappears, I thought that it would be about 300 yen in this Parts configuration as a product.
The installation comes with Instruction Manual, but it has surprisingly gone wrong. Work time is about 45 minutes, and it is hard to get out of Bolt kind ....
Also, I did not remove AIS quietly, it took a shape to cover the end of AIS, which is also a reason for the increase in working time.
If it is necessary to detach AIS secretly, it will be over in about half the time.
In other words, by biting the lid at the final part, the position of the Bolt part of each part shifted and it took time to cause it.
Conclusion, although it is the reason of 2 ☆, it will be the result of considering the price and instruction content and substitution.
☆ I made one more when Gasket was attached with this product.

Fitted in the year 2002 of SR 400
Exhaust System Since After Fire was bad after exchanging, as I checked it, it was getting better if I turned on this, so purchasing and wearing it makes splendid after fire gone loose
