DIY: Secondary Air Filter Removal

Yanked that bad boy out of my 06' no real noticeable difference but shes gotta be breathing better than trying to sucj air through that coffee filter.

 

Ok, so I had decided to remove the filter this afternoon. Thank you for the instructions.
Attached is a picture of the filter and you can see how it could restrict air flow.

 

Just did mine in about 5 min with the intake still on the truck. I left the alu screen on installed a K&N filter. Thanks for the info will post mpg increase if any next week.

 

If this is so then spending any money or time on intake modification on the 2.7 is a waste of time. Think about it: If this dyno is with the stock filter and then with out, what difference does putting a drop in filter that may not filter as well as stock matter. Stock filters are known to be restrictive but at the same time they filter the air quite well. Stating that the K&N may be "somewhere in between" is, well......in between what? there is little or no difference.

I would be interested in seeing a dyno for the 4.0, all stock, w/oSAF, with no filter, with K&N or any variation. I think the results will be similar.

On more point. A good air filter is the one main defense you have to protect the cylinder walls and rings of any engine. A good filter will make an engine last, poor or porous filter will kill a top end.

My top end has valves and valve stem seals and cams. I ordered mine with the cylinder walls and rings in the bottom end.........but I know what you meant.

 

As a techniciann at a repair shop i often wondered what that as there for. I have always thought to myself damn thats gotta be a hell of a restriction.
Coming out of my 06 4.0 as soon as i get the 10 minutes to do it.

 

Opps. Must have just awakened from my nap.....

 

Looked at it today, its already been removed. Im wondering if the truck was previously owned by a tacomaworld member.

 

Hey Guys, I have the V6 with a K&N oiled filter replacing the OEM Paper filter. The secondary filter is still in place but I am strongly thinking about removing it. I am Just hesitant because of the Oiled filter messing with my MAF sensor. Any suggestions...

 

Just pulled mine out...undid 2 clips on the front it came apart and filter on the left I didnt touch, got a flathead screwdriver and pryed the bottom of the secondary filter on the right then pulled it out then put everything else back together....really easy!

 

bump as i was changing the filter today and that secondary one just bugged me. Researching weather i should do it and if prying is good enough w/o messing this up or if i need to take it apart and drill.

 

Since theres 18 pages of posts i didn't read them all. If this was covered sorry. I have TRD CAI, do i still have the charcoal filter or was it removed when i took out the stock air filter/box

 

a screw driver and 30 seconds took care of that thing. Good riddance.

 

My fist through the filter and a swift pull took care of it in about 15 seconds however I have yet to see a gain in fuel economy or performance.

 

took mine out using the drill method... notice some difference.. good stuff

 

why not just put a cai on it?

 

will the cold ait intake get messed up during rainy seasons and stuff?

 

Did anyone ever put a 4cyl on a dyno before and after with this mod? I saw a the dyno results back in the thread but correct me if Im wrong that was a 6 right?
