Stillen intake rattling problem?

Wouldn't the engine vibrations be an issue with the hole cut to fit tight enough to hold the intake? I would think it would rattle like crazy or, at some point, the contact would wear through the piping.

I guess you guys will have to let us know how it works out and if it causes any long term damage.

I know they rub on the inner wheel well on the G37. fix has been to place a piece a rubber inbetween.

I think it's ok if it's tight. I would guess that the silicon couplings would be the point to absorb the movement if the intake tubing is held tight in the hole.

Wow, that is horrible install. Ouch, hope someone got their labor money back. We just finished a gen 3 install and it's perfect, piping doesn't move at all. You just have to make sure the tube hole you cut is perfect. We used a circle saw drill bit to size it just right. Don't let this video stop you from purchasing, obviously someone didn't know what they were doing. Finding a good installer usually solves 99.9% of the problems with aftermarket products.

Mine's been fine so far. There were a couple of spots of concern, but not the holes themselves. More like little tabs of metal that come near the pipes elsewhere. I put little pieces of rubber in a couple place where I thought it might be necessary, but I'm kinda anal about these things anyways, and they probably weren't really needed.

I agree, if it rubs you just gotta loosten the clamps and fidlle with it a little, just like every single CAI ever made!

Ok, after looking at a Gen3 installed with a "snug" fit, I still think a larger opening with a bracket is the way to go.

I'd prefer not to have it rub at the radiator support or flex at the relatively narrow silicon couplers. In my opinion, I would be reluctant to have metal to metal contact especially with everyone explaining that the hole needs to be cut "perfectly" for it to come out "right".

At that point, it's probably less time consuming for the shop to simply cut an oversize hole, fabricate a simple bracket and use an existing mounting point in the engine bay to bolt the brackets down. It will probably also minimize the possibility of scratching the chrome pipes while sliding them through the hole like what you might have with a "snug" fit, especially if you're making adjustments while you fit everything.

The hole is cut in plastic. There is no metal to metal contact other than maybe the AC lines but you can just wrap them with piece of hose. Brackets would have been nice I agree but they are not really needed. Its really a pretty easy install don't let that video discourage you.

An install definitely gone wrong..Simple solution for future self-installers..

Stillen could provide templates for the pipe. Course you could just make your own template..Pretty simple if you ask me.

It's really not that sort of thing. It's not like you're cutting a new hole. There's an existing hole that's slightly taller than we need, but not wide enough (it's basically a rectangular shape, with the longer part vertical). The amount you shave off to fit the pipe is just a small arc on one side of the rectangle, perhaps 3/8" depth at most, I didn't measure. You just take a dremel tool and shave a little from the side to get the pipe through. This really isn't rocket science, and doesn't need a template or a bracket

Got ya..understood :-).. So "Easy does it"..when your carving the hole.

Still undecided . 350(Nismo) or 370(prob. is dealers round me only have 1 stock wrong color and options for me)...

LOL. I just noticed the tags on this thread.

Okay, who's the genius who tagged a thread on intakes with exhaust tags?

Crash · 05-30-2009, 05:43 AM

Interesting... I don't have any tools right now that I'd be able to cut anything at all, so should I just have a shop install them? I haven't purchased the car yet, (maybe by tomorrow though) so I don't know what it looks like. Is it something I could just use sand paper to open up a little?

butters167 · 05-30-2009, 08:17 AM

No sandpaper won't work, I would just go buy the cheapest rotary tool you can find and use it. You can get a basic rotary tool pretty cheap now.
