Do you NEED to disconnect the battery for this? Thinking about doing this sometime soon.
For the 4.0 V6:
It may have been posted before, but don't blame me for asking - being sick messes with my memory: Is the HC Filter located immediately after the Air Filter, in terms of flowing air to the engine?
Finally got around to doing this tonight. Don't ask me why I waited so long. It only took me 15 minutes and I was able to clean my MAF sensor at the same time.
I immediately noticed improved throttle response. Too early to tell if MPG's have increased but I can only assume that it will under the same driving conditions. I'm glad I did this mod and am pissed that I waited so long. Best part about this mod.....it's FREE!!!arty:
How about the noise? Did you notice if it sound louder? thats my only concern before I'll remove mine
Thanks.
Nope, and I drove around with the radio off, windows closed, and no A/C.
My idle RPM is now about 600ish, down from 750ish. Not much but my anal retentive self noticed it. Anyone else experience this?
Edit: A/C off
Your idle did not change. It drops down to exactly 625 (read it somewhere) when it likes and raises to around 750 when it feels like especially with the AC on.
Hello all,
I have been reading the posts in here for quite awhile and did not exactly post anything until I have facts on my hand. I took that crazy thing out in 2 minutes from opening the hood to closing it.
Noticed immediately a much more subtle idle with a bit lower rpm. Throttle response was almost instant when you step on it. After driving it for a couple of miles, I checked the ave mpg and it was at 18.4 mpg from 17.2 with the hydrocarbon filter ( an increase of 1.2mpg! not bad huh?)
Over the weekend, we went to Bakersfield CA. Normally this would be a 3/4 tank of gas going back and forth from Santa Monica. Lo and behold, when we got back, my tank was just a little less than half. The Ave mpg on the monitor was at 21.2mpg.
I would say my average speed was 70 - 75 mph with my rpm playing at the 2k mark. I'm driving a 2005 4Runner SR5 Limited V8.
I'm not saying that all V8's would be getting the same but this is what I got and am very happy with this very simple but effective mod. Does not cost you anything but 2 minutes of your time.
My 2cents guys.:driving:
