Put this in my wife's Toyota Sequoia 5.7 as we've had this type air filter in all our past vehicles. As always, I love that lil extra kick.

THESE 2 FILTERS WERE UNBELIEVABLY EASY TO INSTALL ON MY 2007 5.7 LITER SR5 TOYOTA TUNDRA. I'VE NOTICED A DIFFERENT TONE TO THE SOUND OF MY ENGINE. I NOTICED A CHANGE IN THROTTLE RESPONSE. I DEFINITELY WOULD RECOMMEND K&N FILTERS AND WILL USE THEM IN THE FUUTURE.
