I removed mine for no good reason...same as running super unleaded.

Ditto! No need to remove it. My MPG didn't improve. If you want better performance do the throttle body cleaning.

Did this last night, took 5 mins. Removed the K&N filter, took a flat head screw driver and popped the thick charcoal filter off... Checked to make sure there was no plastic bits in the housing, even though there is a metal deal that keeps crap like that out... put the K&N back in, no issues. Too early to tell about MPG, but throttle response is noticeable. Good little mod

Yeah, I guess people don't read the first post. This was really intended for the 2.7L 4 cylinder engine (which I no longer own).

I did not remove the secondary filter on my truck. However, my URD TCAI completely removes the filter housing from the truck. I have my original housing complete and in tact just in case I want to go back to stock.

yep, on the 4 cyl it does wonders. however, im also thinking about removing the intake resonator as well for increased sound of the throttle body. any body done this? its also called the elbow mod.

You have any pictures of where this is? I did that mod on the cobalts, and it did wonders as well. Id recommended it. Found more info by Searching for "elbow mod" with quotes... Thinking I might remove it, cut it to look factory from engine bay and remount it without the elbow...

(Left piece is inside the fender, partially visible in this photo)

beastlytaco · 09-23-2009, 06:56 PM

me thinks that the resonator and that piece above might be different. can anybody elaborate

WunSick · 09-24-2009, 05:30 AM

That is just the elbow for the resonator, I dont think I will take the full housing out.

beastlytaco · 09-24-2009, 07:22 AM

That is the piece I completely removed from my Tacoma. I had it off my Tacoma for about 2 years. After I removed it, I notice an increase in throttle response. I had no prior MPG numbers before I did the MOD, so I can not say this MOD increased or decreased my MPG.

numbah57 · 10-17-2009, 11:54 PM

I have an 09 2.7, removed the secondary filter and put in a k&n drop in filter...pretty noticable increase in power...sounds sick around 4,ooo RPM...i say it works

McJosh · 10-21-2009, 07:18 AM

Does removing the secondary filter cause the check engine light to turn on? My light turned on after a couple of months but that's all I could think would be wrong.

Dennis1989 · 10-26-2009, 12:10 AM

i know this noob of me and i am afraid to mess up is there any videos of removing the filter or picks steps by steps my email Dennisngo1989@yahoo.com. Thank you very much

removing the air filter will not set off teh check engine light. that was one of the things i was worried about it when i did this. the only thing it does is free up some ariflow to the engine. dealerships will tell you this,(that it screw up your eninge) to try to ward off people from tampering from their shit. but under the magnuson -moss act, tehy have to prove if any performacnce mod is the cause of any issues. they jsut cant calim BS and expect you to buy it. but it will do wonders for your 4 cyl. 6cyl not so much.

Just removed my secondary filter. Noticed quicker acceleration especially in first.

I just had my muffler guy install a Dynomax super turbo (2.5 inch in/out)...what a difference it made! Sounds good too. 20.4mpg 5lug w/ 31 inch tires 15x8 black steelies.

Packguy2 · 11-06-2009, 10:11 AM

Removed my SAF last weekend. Too early to tell MPG diff. but the intake def sounds louder when getting on it.

dunkhi · 11-09-2009, 07:26 PM

so this does increase engine sound?
