This CAI is for a Lexus RC 350. It's impressive that the instructions were for my specific vehicle so if you follow the directions it's an easy install. Took about 45 minutes. The Lexus is a quiet car company. The RC is an exception especially in sport mode. With the Takeda, under full sets throttle it's a sports car. Wonderful sound. But driven sedately it's still a quiet car. After market mufflers are loud all of the time. I had no idea a CAI could transform the car this way.
