I was reading around and I noticed people say that their CAI/SRI improved their gas mileage. I even read on a different forum, someone's gas mileage improved by 100km a tank.

Is this possible with a CAI/SRI?
How much of an improvement can I expect by installing an SRI?

 

I might have only gained about 3 - 4 mpg with mine. But it did make a difference, or so I think.

 

yeh mine made a little difference, but you will find you will drive the car harder and use more gas, just because it sounds so SWEET!!!!! thats what my problem is.

 

i am getting about 30 more miles now with it on and as the weather gets cooler, that number has been going up.

 

I just started sucking more gas...lol it does sound sweet. The best way to save gas is not to drive hard but moderately.

 

Yeah, a little. But not much.

Not enough to worry about it.

 

Funnily enough my exhaust actually resulted in the biggest increase in gas mileage. I went from getting 400-460 km to a tank before to 500-600+ km to a tank now.

 

^^ Interesting...

Im pretty new to cars so excuse my lack of knowlege. What did you change to your exaust?

ps. we have the same cars and we live in the same town!

 

I put on a greddy exhaust system.

 

as did I and I noticed the same thing.... I get about 30-33MPG and I drive my baby hard.
