intake resonator removal/modification QUESTIONS

20192 Views 10 Replies 7 Participants Last post by  astleba13
i was thinking of removing the intake resonator tomorrow

but i came across some free mods that toysrme suggested: http://www.toyotatuners.com/forum/showthread.php?t=158

so i will cut a hole in my intake box as well, below the filter.

and i will try this "harder shifting" mod.

what do u use to plug that big resonator hole? do u get better or worse gas mileage?

when people do intakes i heard that the ecu adjust the air fuel ratio after 20 minutes, on all cars i'm talking about, toyota i dont know. is this true?

when a person does an intake, should they get more or less mpg (better or worse gas mileage) since u are putting more air in the egine. i always thought u got better gas mileage with an intake, since more air, less fuel. but some peole on toyotanation say that the more air u pu the more gas u burn.


any comments, suggestions, experiences, advice? THANKS GUYS

in theory it would get better gas milage but we all know, at least right after u do it, ur gonna see worse cuz ur flooring it to hear the wonderful sound. check out his acitone fuel mix mod too, that will give ya some milage too.
taking out the resonator from the intake dosent make alot of a difference, maybe if you leave it open youd get a bit more cold air, but nothing noticeable. an intake is a low power increase, moreso of a sound enhancer. you just hear more of that vroom from the intake.
that increase in vroom sounds is what i'm looking for. i'm not looking for horsepower from it.
My intake silencers kinda removed themselves, in that I took out the inner fenders for something and it was jsut hanging there not attached to the intake. I didnt' see a difference. I have the piping to make an intake, but I need to get the filter.
UPDATE. I JUST PUT A FILTER ON THE STOCK INTAKE HOSE. REMOVED THE RESONATOR AND STOCK FILTER BOX. SOUNDS NICE. ALL YOU NEED IS AN INTAKE CONE FILTER WITH A 3 INCH DIAMETER AND HOSE. disconnect the battery and reconnect it in a few minutes to get rid of the check engine light.
i removed my resonator ... it gives a lil bit of a diff sound under the hood, but you cant tell inside the cabin

right now its duct-taped closed .... im trying to find a cap that will fit, so if you find one lemme know

the reason why i didnt put the cone filter on the intake hose is that it leaves no place to put the sensor ... unless u cut a hole

but im gettin a short-ram intake this week, so w/e
ur just reflashing the memory I believe and just temporarily removing the CEL, you have to put that sensor back somewhere
^ exactly why i didnt do it :lol:

the CEL is gonna keep comin back unless u put that sensor back in

maybe if u find a cap to fit the resonator hole, u can put the sensor thru the cap?
i ducttaped it to. and painted the hose and tape black. so its less noticeable.

i just let the sensors dangle there. as long as no debri goes inside of them you're fine. the air in the intake box is no different than the air under the hood. so i dont see why they have to go into the new intake. but its easy, drill a hole in the stock hose and epoxy or glue the sensors in. the stock hose is fine. is 3'' thick. no need to buy a piece of intake hose from autozone for 20 plus dollars. all i needed was an intake with a coupler attached to it for my intake to work. 3inch opening on the filter with a 3 inch coupler.

also when you take off the intake hose, clean the throttel body with throttle body cleaner or sea foam. open the flap and spray some to get the carbon out. then wipe the carbon off. wrap a toothbrush in some cloth of paper towel and push it in to wipe off the carbon. suppose to improve your idle.

i hope my mpg doesnt drastically drop, otherwise i'm going back to stock.

I just cut a hole in the CAI tubing and used the stock grommet from the air box the keep the sensor in and sealed good.
