Are Pod filters better than air box?

Compared to pod filters, an air box controls the amount of air getting into the carburetors, has a built in air filter, and protects the engine from water getting inside. While a pod filter technically does some filtering, an air box is much more efficient.

Does a pod filter use more fuel?

Depends, it can increase fuel consumption and reduce power if its not getting the cool air feed it needs. Sucking in hot air will only increase the fuel consumption (especially in stop/start traffic where heat soak will play a part).

Does a pod filter increase performance?

One of the benefits of a high flow air filter is that, unlike regular filters, you don’t have to change it every year. And if your engine is getting more air, then it can perform better.
