Awhile back we had the discussion of removing the stock resonator and intake junk to increase power. I had done this and noticed that my mpg jumped from 32-33 to 37-38. I constantly got 37mpg for 3 months, the highest ever. To test my theory I put all the stock stuff back on and again I got 33mpg at my last fillup. I then took everything back off, except the resonator this time, the noise was getting to me, and I'm back to 37mpg. Now, while thinking about this, the o2 sensor or whatever wants to maintain a certain air:fuel ratio correct? So if the car gets more air, the amount of fuel must be reduced to keep this ratio the same. Does this make any sense or am I just experiencing a coincidential fluke?

It's probably because there is less pumping loss getting the air into and out of the engine.

My car gets crappy fuel economy regardless of my intake. Guess it's because I drive it hard.

I know this thread is a bit old but I figured I'd dig it up to get your guys' opinion on if I should go to the wrecker and get a new airbox and totally gut the sides of it to allow for better airflow. Has anyone done this and what kind of mpg gains have you guys gotten?

Why not spend the $20 that you will to get the airbox for a cone filter instead?

i am quite interested in this increased mpg gains..does n e 1 have a picture so that i may try it on my own? Gas prices are raising these days and to increase mpg's by even 1 will save money. Thank you for n e 1 who will explain or show the install.

The piece that serves the function of the resonator is actually a black plastic piece thats bolted to the blue airbox. You cant see it unless you actually take the airbox lid off.

A guy on the forums (Mervic if i recall) has made a cone filter air intake. PM me with your email if you want the picture of what he did.

Like this?(the one on the left)

I got about 2-3 extra mpg when I did that, probably would have got more but I can't seem to keep my foot off the gas! I've never seen anyone do something like that for a GA (probably because of the stupid ass shaped filter)but I'm sure it's possible. There are people that have already made CAI for the GA and I've seen one for the E16 with some custom piping and a cone filter.

that blue top looks like a CA20E?? and i think i'm going to go ahead and suck it up and try to do some sort of half assed CAI on E16......it'll be completely ghetto and back yard mechanic styel but it would be a basis for anyone else to do better with.

I guess you're talking about the pic on the right, that's a VG30E in an '85 300Z, and yeah, I think they look similar too, very creepy!

holy hell...it is...i didn't look close enough. i just saw the blue top thinking it was valve cover not air intake thingy (mind is going south tonight)...and the distributor looked in the right spot.
