lol, the cars you listed above are 8cylinders? correct me if I'm wrong(besides the evo or wrx), or come with stock turbos. Honesly cai and sri dont do much for four bangers. Atleast not worth 200+ for a name brand.

Even the Lexus RX400h hybrid has CAI and that engine is not exactly a horsepower monster. While it is true that the smaller the engine, the less absolute gain you will achieve, the percentage of HP increase is very similar.
