Well, I was in the middle of changing my spark plugs when I realized that I had taken the entire intake system off of my engine. Instead of putting it back on stock, I jumped in my buddies car and headed on over to the hardware store and picked up:

(1) 1.5" PVC end cap
(1) 1" PVC end cap
(1) .5" PVC end cap

(2) Hose barbs
and some fuel line

I followed the write up by "96 4Runner"...and it was very simple, Im suprised not everyone has done this mod!! It was easier than doing the deckplate in my opinion.

What I noticed off the bat was the slightly deeper tone to my exhaust at low RPMs and a louder throaty sound when gunning it. I unfortuently changed my sparkplugs and did the ISR mod at the same time, so I dont know which gave me more performance. After these upgrades, I noticed much stronger acceleration, and a much "punchier" feel to the gas pedal. Plus, the sound is great.

The only problem I ran into was getting the .5" end cap into the smaller hole. I knocked it down there with a rubber mallet for a while, and had to stop due to the fact the main intake tube was starting to tear. Not too much of a big deal though. Everything else went very smooth.

 

but you ddint include pictures

there should be a rule that you cant post that you did a mod without pictures

 

DOh!

Okay, well, I'll take a picture of what it looks like right now

 

Here.

 

hehe, looks just like mine....except i put on a big K&N filter as well. i dont wheel so i have not water stuff to worry about. the sound difference is not very much until the airbox is removed, sounds nice with just the isr, powerful with the isr and no box

 

Did you get an increased "whistle" sound? When I did the ISR on my S/C'ed 3.4L I didn't notice any power gains, but I got this annoying whistle/whining sound..

 

Well, I have the decplate with a K&N drop in...so the sound was increased qutie a bit.

SLC, nope no whistle. I have a pretty heavy "sucking" sound when I gas it though. I like that sound

 

Do you still have the whistling? You didn't happen to knock off a vacuum line did you? There's one that sits below the throttle body that comes off a bit too easily. If that's pulled, then you'll get a nasty whistling sound. I did that myself and didn't find the cause for .. 13 months.

 

Hey Mark,

I only kept the ISR caps on for 3 days. When I removed the caps and put on the boxes, the whistling sound went away..
