It's going to be really annoying to switch out the intake, do you guys have any other tips? Do intakes cause codes to be thrown?

We have not seem random misfire codes from installing our intakes, but I cannot comment on the K&N as we do not see them as often. Anything is possible, but for an NA application it is a little odd. No other codes other than the random misfire?
