If your local Depot or Lowes carries anything from Fernco they can get it. If not you can buy from Fernco direct.....look up there site on Google.

yes you can use the stock air filter, its the same size as that K&N filter they are using. the reson i know, is lots of people i know use that same K&N filter in the stock airbox. i tried the K&N filter didn't care for it much, i can make a stock one last 2 years, and its still as clean as the day i bought it.

CKTA, I did a similar mod using your information but wanted to eliminate the accordian hose and make a more straight thru, restriction free system and also be able to untilize the stock filter as well. I used the 3" Fernco coupler to attach the MAF to the stock intake pipe then got a Fernco 3" Qwik ELL to attach to the MAF and go to my filter end which I attached a 4" section of 3" PVC. My stock filter was rather loose on the 3" PVC so I put a clamp around it and tightened it down snug to the pipe. I drilled a 11/16" hole in the Qwik ELL to attach my IAT sensor and then got 2-3" pipe hangers to secure the MAF to the engine dipstick holder mount and the other to secure the PVC pipe to the firewall. I also eliminated the large square box on the back of the intake portion(the one that has Vortec on it) by using a 2" Fernco Cap on it. The whole installation looks really clean and clears up alot of room on top of the engine. Came in very handy when I replaced the distributor on my truck! I can use stock or any other clamp on cone filters with this system. The noise is slightly higher, but can definitely feel the pick up and more power on the road. Like it so far! Also,Lowe's was the only place I could find the pipe hanger at, nobody else could find it. I have pics of the finished system but cannot seem to find a way to post any pics. e-mail me if you would like those pics. mark@muzzy.com Mark

Not sure what a fernco coupler is, but I just used a 3" Rubber coupler (forgot the name brand, it didnt even need to be 3/12") and it worked perfect. Very good mod, throttle response is so much better!

The rubber coupler you used is a Fernco. Fernco is the company that makes them. Glad you liked the "mod".

Just wanted to add some info on mounting. I bought one of these pipe hangers (black plastic coated) at Lowes. They come in various sizes. You just bend the bottom and mount using the holes.

I am not running anything holding mine down and it rattles at times and sucks.... I'll be looking for one, Lowes is down the street, across from Home Depot!

[WetPaintYukon]

I went to the home depot in durham, nc and asked where the fernco couplers where and some asshat pretty boy that had no business working in the hardware section started laughing and asked me what in the world I was talking about. Needless to say he had no idea even when I explained in out in fvcktard terms and they didnt even have 3.5" to 3.5".

So now im gonna get off my a$$ and just order it on the net.....

[N0DIH]

They are commonplace in the plumbing section, they are with the white PCV stuff.

We have Menards as a local home improvement place too, of HomeBase out west, or Lowes or even a small hometown local like TrueValue, they should have them.... Very common parts.

[theunforgivenll]

just to help clear somethings. alot of ppl are looking for 3.5 to 3.5 couplers and not finding them. keep in mind that when they refer to pipe being 3" that is the inside diameter so the outside diameter is 3.5. they being said when you buy a coupler that is for 3" pipe it is going to have a 3.5" inside diameter, witch we need to slipe over the maf. so when i pick up my coupler it said 3" but it had a 3.5" inside diameter that fit the maf perfect
just thought i should add that b/c i too went out looking for a 3.5 coupler

[lowbravada]

I got mine done yesterday and went 100 miles and it is getting around 2mpg more. Thanks for the info. Oh yea and i just used the stock maf coupler it worked fine for me. I'll get pictures up tommorow

[lowbravada]

Once i get a k&n it will jump higher im sure. It's just the stock filter right now. Ithink alot of it is getting rid of that tight 90 right after the maf

[Maduag]

its a decent mod. I did the EXACT same thing to my truck 4 years ago though
