as promissed.. Lower Intake Resonator removal DIY:56K warning - Toyota Nation Forum : Toyota Car and Truck Forums

Alot of you have asked me how to remove the lower resonator. So here it goes. Note: i nor this site are liable for any damage you cause to your car in the process of doing this. also, the 1st time you go to start it when your done, it will probibly just stall right out. Just start it again and it should run fine. Just let it idle in drive for a few mins. And take it around the block once or twice

Step 1: Get your tools. Ratchet, 10mm ratchet attachment, and 10mm wrench, and a flat head screw driver.

Step 2: Remove all clips holding the radiator cover on. To do this you simple push the center of them in, and pull them out. This is what it should look like once removed.

Step 3: now that you have all of the clips out. You can get the radiator cover out and place it aside

Step 4: Remove the 2 outer most bolts on the intake with the socket wrench

Step 5: you can now pull the top section of the intake off. Be sure to unclip the vacuum lines and wires that are connected to it

step 6: Now remove the bolt that is holding the lower intake. You can then pull the lower intake out.

SIDE NOTE: at this point you should have these parts removed. Radiator cover, upper intake, and lower intake.

Step 7: Now its time to remove the battery. First remove both leads from the battery terminals with the 10mm wrench. Be sure to disconnect the negative batter cable first, and install the negative battery cable last. It's safer that way.

This is what it should look like with the leads removed.

Now you LOOSEN the nut that is closest to the air box. DO NOT REMOVE IT

Once you have it lose enough to where u wan wiggle the back part of the battery holder, you can remove the bolt on the front of it

This is what the battery and battery harness should look like once removed.

Step 8: you now have a clear view at the resonator. So you can now remove the bolts holding it in. The one on top u can remove using the socket wrench

Now that you have that bolt removed, there is a plastic screw that you can just pry out with your flat head screw driver.

You can now remove the resonator.

You can now put everything back together (except the resonator of course) I personally do it in this order. Lower intake, upper intake, battery, then radiator cover. To get the clips ready to hold the radiator cover in, push the bottom of them in until they look like this:

Then, you put them in the hole, and push in until they click.

nice writeup! you actually taught me how to properly attach and detach those clips! i broke 4 of them in my trunk when i was sound dampening it lol

did u hear a noticeable difference, if any, and what exactly were the benefits?

With the bypass, k&n filter and the resonator removal, it does sound better for sure. And the lag from DBW seams to be almost completely gone. And see that, we all learn somthing new every day. Im glad i could help

what is this bypass you speak of? and would it be the same with the 4cyl?

I did ask before but I don't believe any answered my question. What does this resonator do? What is it's function?

this is my video of me doing the bypass

and this is with the bypass and resonator removed

I don't think the I4 has the same intake situation as the V6. I know i couldnt do the bypass on my 2005 I4 because there wasn't anything to bypass. And i didn't bother with the resonator because it would still be as slow as a dog. lol

to quiet the engine, but it also restricts airflow.

Any change in MPG?

I did the simple air vacuum valve that you said in 1 of your video and did notice the RPM at idle was a tiny bit higher. On the power side I didn't feel any. Anyway, I didn't like the higher RPM much so I put it back so it won't reduce my mpg.

Thanks for the idea though.

I did buy the K&N air filter like in your video though.

I didn't notice the power increase on that change either. I guess I am just "insensitive".

That is a great "how to" write up.

Be sure to disconnect the negative batter cable first, and install the negative battery cable last. It's safer that way.

Resonators deal with the noise waves above all else. Cancelling/reducing noise waves doesn't increase power, just noise.

If you think noise increases power, play a sound clip of a Ferrari while you're driving your Camry. It won't be faster, but it sure will "sound" or "feel" faster...

Great suggestion! I will install a speaker near my exhaust to play back a Viper's exhaust note...

I didn't think that resonators did anything to restrict airflow, it just absorbs/dissipates some of the sound and vibration to reduce noise.

to be 100% technically correct - any passive resonator (vs active noise canceling) creates some airflow resistance to be able to absorb the waves ...might not be enough to have any meaningful effect on performance but from physics standpoint of view. I think the point is that the OEM system with the resonator in place has plenty of airflow already.

Resonators can also INCREASE air flow.
