DIY high-flow intake for $43.00 - Toyota Yaris Forums

Hey guys, and gals, I tried this about three weeks ago, but without the K&N Filter. I just removed the tuner tube and drilled two 2 1/8" holes on the side opposite of the tuner tube with a hole saw. Im kinda wierd in the fact that I like to take mods one step at a time to what changes and by how much. Just removing the tuner tube changed the engine sound a little, but nothing in the way of performance or mileage. After a week, I drilled the two holes in the air box. Immediatly the engine sound was in fact deeper, but over the course of several tanks of gas, I have noticed an increase in MPG. I've been getting an average of an extra 20 to 30 miles a tank before filling up again(usually 9.5 to 10 gallons). Most of my commute is 75 - 80 mph on the interstate and the rest short city driving trips, and I am by no means easy on the car. Hopefully after this friday I can get the K&N filter and see what increase that will get me, if any. Also, the stock filter is still in good shape, not overly dirty or oilly. I have just over 13,000 miles on her, so a replacement is due.
