Has any body put a cold intake on the gs 300 if so any diffrence in horse power or speed

 

Since the stock intake box is technically a cold air intake because it pulls cold air from the front of the car. I just used the pipe from the Injen intake setup that I bought used along with K&N drop in filter. I don't have dyno numbers to back it up but I felt and slight increase in power and throttle response. I also saw a slight increase in MPG. If you want to go further you can wrap with the pipe with some sort of heat reflective material to help reject the head produced by the exhaust.
