See, best thing you can do is, not to install a K&N. The marginal gain in performance often comes with heavy prices.
Now, if you have already got one installed, then upjetting is a necessity. Upjet your carb, get a better breathing engine and forget the mileage part. K&N without upjetting and a simple tune up will sure over heat the engine.
So either do upjet or go back to stock filter.


So getting drenched every day.
