I have the Fujita CAI installed and not worried about the warranty....Sparks Toyota sells them (or did at one time) without any disclaimer on the warranty....DIY of bolt on products will not void the warranty according to the Scion Service department that I deal with...there have been other posts on this that say the same thing.xbam27 said:I have a 2010 as well. I wouldnt chance getting any other CAI other tahn the TRD one. I am all about tuner, but I am more about keeping my warranty. Anything that has to do with performance will be installed by my Toyo dealer. IMHO. Best of luck.
