Hi Everyone, I am new too all these, but here is my question! I recently have my 1.6EL air in-take modifid with something that looks like the K&N FIPK Fuel Injection Performance Kits. Question is, someone said 2 things to me, which I am not sure if it is true!? Can someone tell me Yes/No and why!? 1> Modify the in take, w/o the exhaust would decrease performance, because there is too much air going in, while the exhaust doesn't have the room to allow the air to comes back out. 2> For the same reason, it is also harmful to the engine itself, since too much air go in, but while the OEM exhaust is too restrictive. PS: Wouldn't the Fuel injection computer, would automatically adjust itself when extra air-flow is available, but also keep the exhaust restriction into calculation.?? Regards, Eddy Lau
