everyone heard of it.......
do a search for it but just to let you know the Injen intake and the RMM intake both made the IS lose power.....

Hey macclarin how do you know that the injen intake make the IS lose power. I thought injen makes good intakes for all cars. Oh yeah i also have the 5 zigen muffler on my IS. I don't know if that will make difference with the intake
