I tend to wonder about some of these intake systems. My little brother has a honda and likes to sink money into the motor. Well he found out that the after market intake system he bought actually caused him to loose 1 hp from his previous run with the stock system. Go figure. And it was guaranteed a 5hp increase. Some work, some don't. I had a 3rd Gen RX-7, and an intake on that thing gave you a huge increase. Maybe because it was a rotary. Who knows. I think anyway has got to help our little 3.0's. BTW I read a post about what the ECT button actually does....Thanks alot. I can't keep the dang button on normal now, and my gas mileage is starting to stink. I think I might need to check out the K&N.

 

www.gadgetonline.com has dyno results from removing the front of the air box and not just a 4.5" hole.

(http://www.gadgetonline.com/airinduction.htm#Modified Air Box:

The gains of removing the front of the air box are impressive. But I really like the idea of being able to replace the removed section by using a faceplate. Do you think the gains could be say 2/3's those of removingthe front ofthe air box?

 

Well I have been following this thread for awhile now....I was debating whether or not to particpate....but decided, hey, might as well throw in my experiences. I agree that perhaps K&N filters aren't the best for engines as far as filtration goes, but when faced with basically zero alternatives.....I installed mine....This is of course before I read Gadget's article. Now I carefully monitor my K&N to see if any contaminants are getting in....I basically wipe down the inside of my K&N, the ends of the plastic elbow, and the opening of the TB with a clean white sock.....So far the white sock has stayed white. Maybe I've been lucky with my K&N...or maybe it's b/c I haven't been driving anywhere that's really dusty...

As far as performance goes....it's like driving with the ECT button on.....more responsive and a nice sound too....

Regrets none so far......

Future plans....keep my current K&N clean and install the amsoil when it comes out.....to give it a try....

Thanks,

Roger

 

Well, for what it's worth... I ditched my K&N last week after I discovered a very dirty filter and oil migration onto the filter housing. I put it in stock out of the box so over-oiling was not an issue. It did seem to help performance a little but the oil residue is not a good thing in my opinion. I ran one without any problems in my 5.9L Dodge Ram but I didn't want to take any chances especially after hearing stories of MAF sensor damage by some. Since AMSOIL is not available for the 2nd gen I am considering the $120 investment into a BATTLEZ/JAOS filter. Anyone out there have any experience with this filter???

 

HUH??? :eek: :eek: :eek: Please please elaborate!

People with over-oiled reuseable filters have found that there MAF sensors are being covered with oily residue/gunk, and once they are cleaned, they notice a different in truck response and performance.

 

Hey everyone,

Is there anyone out there running their K&N on a STOCK setup. It seems like everyone here is running cat backs or headers.

It seems also to me that the K&N is know for allowing more particles in the motor then say an amsoil filter. Of course I wonder wether this was just propaganda. Of course amsoil supposidly doesn't make a filter for the 3.0L...

We need some DYNO numbers! I don't want to invest 200+ dollars and then find out to get the whole gain I have to spend anothe 400-1000 dollars on a cat back coupled with some headers?????

ANY BODY HAVE ACCESS TO A DYNO???


WHATS UP WITH THAT!!!!!

How much does dyno time cost? I'm curious about how much my setup is netting at the rear wheels. My SOTP (seat-of-the-pants) dyno isn't too accurate...

 

Hokiez97: I ran my K&N FIPK for a little over a year before I got my cat-back system. I don't have access to a Dyno (I don't have a need or reason to Dyno my 4Runner). But I can tell you straight out that you WILL feel a very noticable difference in power and throttle response if you install a FIPK on your truck (That's what happened with my 91 4Runner 3.0L, I've heard different if you have the 3.4L Engine though) So in my opinion, if you have the 3.0L in your truck then yes you will feel a noticable difference in power (especially if you're running a stock truck). And also in the over a year that I've had the FIPK installed, I have NEVER had any problems with it. You just need to make sure that it's properly oiled, and not over oiled like CTB said.

On the other hand if you're running a 3rd Gen 4Runner (or a truck with the 3.4L Engine) Gadget on here has done research on it and found that it actually decreases performance (I'm not sure if it was just on a the Supercharged Engine, or both that and the regular 3.4L) But the FIPK does indeed help and increase the power and throttle response on the 3.0L (3VG-E) engines.

Too bad Amsoil doesn't sell a hig flow airfilter for 2nd gen's.
This logically. If you give the engone more air, it will run better. Less restrivetive air flow, more air to engine...
Also I have hard that the overbore throttle body is a good mod for horsepower. When I emailed them they said 5-7 horsepower for like 250 bucks( figure might change). I do not know if it helps torque?
