This car has no engine tuning parts. Sorry the air filter is not a tuning part. Not when your intake duration is fixed. You can't buy cams for it either since you want to rev kaw kaw.  Buying noisy exhaust also will not make your ca go faster. Since your engine dumps a fixed amount of exhaust gas from the fixed engine capacity.

You want play engine tuning, go for turbo cars. N/A engine after RM20K also cannot get 50HP like turbo.
