Yes, your fueling will be fucked up, your motor will wear out quicker due to poor air filtration and you will be offered all sorts of snake oil and charlatanry to fix, at a price, a whole load of issues that won't exist unless you head down this fruitless and damaging path.
As an alternative I suggest you buy a set of dirt cheap cables, download Guzzidiag, learn how to use it and take advantage of the generosity of others who will make your bike run a whole lot better.
The stock air filter is the LEAST of the GRiSO's problems!
