Anybody tried this? Not for boost hoses - this would go between the air filter and MAF.

Says vacuum rating of 11inHg for 3" tubing (which I have a bunch of it). Not sure how much vacuum is generated ahead of the throttle plate?

Just looking for quick ways to relocate the air filter and get some cooler air from behind the fender.

 

I think I've seen this used on turbo inlets on race cars, gotta look for some pictures. I do know people who have had standard silicone hoses collapse under full throttle when placed between turbos and MAF's so there is a decent amount of vacuum. Not sure how much though.

 

You want the walls of your intake as smooth as possible. The corrugated walls will create turbulence which will lower the intake efficiency. You want this flow to be as laminar as possible.

 

I stopped by a friends shop to get some chunks of 3" tubing so I could butt the tubes together and it turns out he had some decent sized chunks including a nice mandrel bend 90.

Wound up doing it all out of pipe. Stock M-Tune filter tucked in the far corner of the bumper. Snug fit but fits.

I'll do some logs over the weekend and creep in traffic a bit to see the difference. I'll have to come up with a way to seal the gaps a bit to make sure it stays dry on wet days (tho I rarely drive it in the wet so at this point I'm not too worried).
