Is there a good source for this hose without paying an arm and a leg at the stealer?

I've always thought the "accordion" hose was the x-over->IC inlet hose, sometimes called the Michelin Man hose. The MAF->turbo inlet hose is pretty different from that. ;)

You can find a Michelin Man hose pretty much any time someone converts to Samcos. In fact, I thing you can get that in a Samco flavor for somewhere near $75.

The MAF->turbo hose is harder - Shokan or Force 5 to start. ISTR someone selling replacements made of silicone in the stock size, but I can't remember who that was.

Mine is leaking and the car is running ****ty under load.

The one I think you're talking about is up top, and can be accessed with the hood open. $90.

The Michelin Man hose is below, accessed by taking off the undertray. $75 (or so), Samco, ECS tuning.

so where do you get it from?
