diy intake tube

[tdarty77]

My stock intake tube has seen better days thanks to a previous owner! Any suggestions on making my own intake tube? I plan on running the Tymar knock-off filter from napa. Thanks, Tim

I haven't gotten to that point yet with mine, but I've thought of useing 4" steel exhaust pipe. But, I also have a shop with metal working tools to make it with bends and such to fit perfectly, that might not be availible to everyone. Also thought of using PVC pipe, but then you have to find some way to bend it, as a straight peice wouldn't work from the turbo to air filter, and the fittings (elbow's and such) would get bulky, if they happen to be the right angle...

Just some ideas, hope you figure something out... keep us posted!

Yeah, the bends would certainly pose a problem. I thought about the exhaust pipe but I don't have a tubing bender. Thanks for the suggestions.

you can buy pre-bent exhaust tubing from napa, that's what I did.

Great idea Dalton... I'm gonna remember that, tryin' to talk a friend of mine into the DIY intake, but the early '99 he has isn't as simple as I remember my '00 being. The stock tube fit right up to my filter once I removed the stock air box, and all I needed was a 3" long pc of 4" exhaust pipe, and an extra hose clamp to fit the filter. Yours looks like you replaced some of the tube going back to the turbo, perhaps beyond the CCV hose, if you have done the CCV mod... The bent pipe you used put's me in mind of an E99 truck, but your sig lists late '99. I remember looking at my friend's truck, and thinking the bend needed to put the 6637 filter in there would need an elbow like you have... both of his are deffinitely E99's. Thanks for postin' the pic...
