It makes perfect sense. CAI pushes more air into the engine, if the fueling can't keep up, there will be too much oxygen particles per fuel particles and that'll lean out the car.My SA said don’t put one in (I did anyway), saying that Toyota’s official line is that the CAI causes damage with too much air causing the air fuel ratio to be too lean. Of course, this makes no sense. My SA also said “any performance mod” will be blamed for whatever might go wrong down the line.
My STI couldn't accept an intake without tuning for it. If you had a downpipe too, you needed to upgrade injectors and fuel pump as well because the stock fueling system would not be enough.
Intakes are very important now. That's why they hardly make power, and often lose power, with aftermarket parts. Because they're so highly designed by the manufacturer.
