I need DIY instructions on how to install Injen SP cold air intake on my 2014 Is350 F sport. Anyone have instructions with pics/videos? Thanks in advance.

 

its not difficult at all just remove the air box box lid, then remove the box itself by the two bottom bolts, remove the stock pipe to the throttle body.

put the intake coupling to the throttle body, install the pipe bolt down in same spot as the stock intake lower half, install shield if there is one, and put the filter on.

 

You could try heading over to the K&N website and finding the system for the 3IS, on the product page they typically have a PDF for installing and uninstalling

 

reference the link, should help guide u...same motor ....

 

r0shio has a DIY Intake install thread on here

 

that's a good video linked above. if you want more, just look up diy 2nd gen intakes on youtube.
