My take on Blu's Air Silencer Removal Mod 2nd Gen.
#21
Yeah they need to be the size of the threaded ends of the brass fittings. They go on the threaded end of the brass fittings inbetween the nut and the tubing wall on the inside. The nuts I bought were the thin wide ones so I didn't even see the need for washers. Just make sure to tighten em down really tight and use that lliquid Lock-Tite stuff on em so they don't come off.

Haven't found any at all Scofo. Says your in the Yukon though...wonder if the metal piping might make a dif in that extreme weather you guys get. Maybe not though once everything warms up inside the compartment. Could always find a way to insulate it somehow if that were a concern i guess.

I don't see any reason that cold would be a factor, I mean were working with an injected system and supplying better air flow. We've been hitting 32 degrees F for he last several nights here and I haven't had any problems, then again it's only fall. I look at it as just being a bit chilly.

Dunno if it would or not....Just thinkin -60 degrees farenheit coming into the intake when you first start up might be a problem. Weird things happen in those temperature ranges. Lot of people up there use block heaters though. Course in WI you will be a test bed for close to that Dublin.
Might not be a problem also. Guess as long as the engine compartment is warm, no probby.

warning to all : using this flex pipe if you drill it wrong, the rings that make the pipe can get streched and then the pipe is worthless... the hole we drilled streched really huge and we couldn't get it back together..

Mikro has a point with the cheap piping...buy the heavy guage good stainless, follow the directions above and use a sharp bit and you'll be fine.
Oh make sure to debur everything with a Dremel honing bit or sandpaper as well.

Well, I think I'm going to have a muffler shop bend a pipe for me...tracking down the flexible stuff hasn't been easy. I have found a place that has it, but given that it may destroy it if drilled wrong, I will just do it like Blu did.
Also, and this is weird, but there is only one connection that goes into the tube at that portion of the pipe. It is, I'm assuming, a PCV valve that comes from the head cover. There isn't anything else connected to the intake...I have looked and looked. Unless I'm missing it (hard to believe), but I only have one. Anyone else run into this?
I should get this done on Friday...I'll post pics!

The blanket does a nice job of keeping all the heat in there that is generated.
Alot of people also use remote starters that can start the truck every 2 hours for 20 minutes or so while they sleep.

Like I said only reason I went this route was that I couldn't come up with mandrel bend for less than $30. This worked great for me! If you have access to a bent piece or someone to do it by all means go for it Greg!
Scofo...Brrrrrrrrrrrr

I 'think' I can find a muffler shop to bend the pipe. This is on the agenda for tomorrow.
I'm still a little puzzled as to why I only have one connection going into that part of the intake. Everyone else seems to have two. The only one I have is the larger of the two that I have seen in pics and it comes up out of the valve cover. I guess it's not a big deal and it makes the job a little easier. It 'may' be hiding underneath somewhere, but I couldn't feel it.
Weird, but I'll report in tomorrow with my progress...!

Look under the filter box, there is a second (resonator) box that is connected to the silencer ducts. There is a 7/16ths inch hose connected to that box. That's the second hose Greg.
That's the box on the left. The little nipple on top sits right next to the radiator. That's where the second hose connects:

Bump. Warning to 1st gen owners added to 1st post. You will have to figure thiis one out if AdamF hasn't before proceeding. Shouldn't be too difficult but it does mean some changes.

Heading to the exhaust guy tomorrow to do my high flow cat and flowmaster...i'm gonna see if he has any old 3" tubing laying around and maybe bend me up one and I'll stop down at my father in laws plumbing business and get me some 3" fernco's for each end...then all i gotta buy is the brass fittings and mine will be done tomorrow!

Awesome Thread Everyone! I would like to thank everyone that contributed. There is pride in craftsmanship, and a project like this on my 93 4Runner will be something to show off in front of my grease monkey friends. I look forward to placing this project on top of the to do list. Saving money on gas and getting places faster will make the rest of my plans easier to complete.
I live in Corona CA and it gets really hot out here.
I am going to start out by using this method.
Then,
I'm thinking about using the mandrel bent pipe method and wrapping it with motorcycle header pipe wrap to keep the pipe cool inside. From what I hear, cooler air makes for better performance. Just a thought. Thanks again!
