#28551, "Adding coldair filter to stock intake piping"
I have a very limited(nonexistant) budget and wanted better sound out of my 420a. I tried the stock airbox mod and wasnt satisfied with the sound. I bought a 20$ aftermarket air filter, removed the airbox and stuck the filter on the end of the stock piping. The engine now sounds great. My question is will anything bad happen from doing this?

nope, people have done it (i tried but my filter and tip of intake are SAME size so it wont work) just make sure you fasten the filter to something to reduce movement

You really need to clamp it down to the intake pipe. If you don't get a good seal, you might as well not even have a filter, especially if it falls off when you rev. I took a small piece of left over chrome intake pipe that was 4" long that I got from a speed shop for free, and stuck it in the stock intake tube with a hose clamp, then stuck the air filter to the end of the chrome piece. I would definately recommend doing this.

PVC gets soft from the heat from what I hear. I guess any metal pipe with the right diameter would work.

I ended up using ABS plastic piping....and I sure hope it doesn't melt, don't really see how it could though - pretty sure it doesn't get that warm under the hood for the intake piping to melt.

PVC pipe can withstand real hot water so i would assume it could withstand hot air. Does the intake really get hot enough to soften/melt it? At autozone they had pieces of exhaust piping, would that work? They only cost a couple dollars like the pvc pipe. I'm trying to do this very cheaply.

a k&n cone w/ 3inch inlet 5inch length will fit the stock pipe. when you put them side by side they look like the same size, but the k&n will slip in a few inches, you just gotta mush it around and slip it in. fasten it up and drive around a little bit, the heat expands the stock pipe then you can slip the filter all the way in and clamp it good. this way it wont fall off.

I went a little farther than all of these guys. i took one of those 20 dollar filters then i cut the stock tube right above the ribs. The filter will fit right on and now you have a short ram intake. Even tho everyone says it will not work right, and you will suck nothing but hot air, i still feel a little boost of power and have a good sound. Try it if you like.
