Plazaman vs Injen piping
 

Which is better? I think the Injen uses a different intake whereas plazaman uses stock cold air intake.

Plazmaman.

Neither, its a waste of money--you will get bigger piping--sure, but that slows velocity of air and the next restriction is at the TB which is even smaller---so not going to do anything except move power band to rt a little and hamper low and mid range.

Running injen piping without any drama. If availability isnt an issue , get an ETS piping.
