well, if you stay at a steady speed, you'll get good mileage, but if you want more, you'll have to coast. every time you coast, ur mpg will go up. for example..... slowly accelerate from 50-55mph to like 72mph and then coast in neutral. i usually leave the engine on, but if i go extreme, i turned the engine off. now, if you're current trip mpg is at let say, 40.0mpg. as you accelerate SLOWLY your mpg will go down, but slowly. now your current trip mpg should now be around 39.7-39.9. once you start and finished coasting, your current trip mpg will go up to like 40.4 - 40.6. and you just keep doing that and your mpg will go up every single time, of course that's if you do it correctly. once you get to the 50mpg range and coast, it will only go up like .1-.3, so 50.1-50.3. the higher your mpg, the harder it is to raise it up, but its not impossible, just gotta try very hard and go extreme. keep in mind, if you accelerate quickly to the destination speed and then coast, its not gonna work because of the extra gas USED to speed up. also, acceleration is what kills mpg, so gotta be gentle on the gas pedal. if i really concentrate, i can do 40mpg acceleration and even 50mpg acceleration in 6th gear. hope this help. best to date mpg is 52 mpg with engine on & 57mpg with engine off. keep in mind, i have a Si, not R18. maybe i should do a video, so everyone can have a better understand.

I have a CAI on my car. i wanted to get as much cold air as i can to get better mpg, but i haven't notice any difference. if i did get better mpg, it would be like 1-2 mpg better, but i doubt it. i've already order NST Pulleys to see if it makes any difference, but i haven't install it though, don't know how to. i'll give an update on my mpg once i figure out how to install the pulleys.
