Ok guys I tried to search but came up with zero results. Just a quick question about sizes. For a stock MAF and stock TB what size of tubing do i need to buy?

Do yourself a HUGE favor and keep the stock bellow. I've been down that road, and wish i had turned around before i got there lol. I've got the stocker on now.

It's 3" in/out, and its 4" long. Fernco part number is 1056-33. And here's a picture of it, you can see it in the background

I agree. Keep the stock one, so when your engine torques, your air box stays solid, something flexes. I have been looking for something / same way to make them flex more. Unless you are really trying to clean up the engine bay and go for a color scheme, there is no reason to. Its <1 hp, and can crack your lid.

Not to steal the thread but will a fernco piece work for me when I switch to a FAST 90/90 setup? I will still be using an SLP lid with a stock MAF and I don't know if my SLP bellows will work.

In the fernco section, i think they have a 3" to 3.5" ,and also 3" to 4" reducers. One of those will probably work.

I'm running the 3 to 4 inch Fernco with the Fast 90/90. Fits nicely!

If you have poly motor mounts then the flexxing wont be and issue.

I used the 3x3 had np.The secret is to heat it up in the microwave.A minute here then a minute there.So the heat spreads thru out.Then stretch it out or pull it as quickly as possible before it cools and get to the throttle body,and with a lot of wd 40 it should slide right on.Oh yea the most important thing is when you take out the old one match it up with the 3x3 and cut the same angle on both ends.That will give you the curve that you need SO THAT IT FITS NICE.

I just finished this using the 3x3 fernco. May not be much in HP gain, but it was the least expensive, easiest mod i've done to date. I have a voretx throttle body spacer on my TB so I had to cut the thing nearly in half. Boiling it in water for 10 minutes made cutting and installing it a snap.
