Default COBB Silicone Intake Tubing

Anyone tried the COBB Silicone intake tubing? It looks like it would improve airflow by removing the corrugated portion of the stock intakes. I'm not sure if this is the real restrictive element though. I'd love to see some dyno numbers. They're relatively inexpensive, but are a decent down payment on a real CAI. Thoughts?

Nice find! This woulda made my job a LOT easier and only a few bucks more than my fabbed up hoses. These are a no brainer...
We're gonna go this way when I build the intake for Zpirates car..

So, Modshack, you think they are worth the $125 and potentially negate the need for a full CAI? Obviously they don't make the intake air 'cold', but the stock airboxes do a better job of cool air intake than any of the short tube options out there. My guess is these hoses may make a measurable dyno gain.

I was wondering about those myself. I don't remember seeing color choices, but I could be mistaken.

I'd be interested to see if there are any gains if you replaced those sections of the stock intake with this.

From what we've seen so far is that the stock intakes flow very well up until the very top of the RPM range... that's where the LT intakes actually gain over stock. I don't know if those sections of the pipe become a restriction or if it's something else, but it's pretty clear that the stock units are pretty good.

Well....I don't think they are a substitution for a well engineered aftermarket system, but just having a larger ID crossection and a smoothed interior has to help with flow. I'm betting the Silicone will heat up less than the metal typically used in most CAI's. I wouldn't expect any measurable dyno gains outside of the statistical differences expected from run to run.

Yes, I agree that the stockers would seem to be pretty good. They match my system (and the Stillen G3) for intake temp control which is a good thing. A Cone may flow a bit better than a flat panel and Box...Regardless, smooth hose downstream of the filter should help. Not enough to make a Kick-*** difference, but I believe that enough small, incremental improvements ultimately result in nice overall performance gains.

Everytime I see these I always think why not at least buy a short ram but since there are 2 intake on this car the money adds up quick.

Short rams pull air from the engine bay. The stock boxes are nicely designed to pull air from the radiator. Pull out the drop-in filter and have a look. The stock system is better than any short rams you can find.

What is the reason for most cars having the corrugated tubes, ease of fitment or does this help break up the air flow, kind of like how a spoiler will decrease drag. Maybe it increases the air flow, I'm no engineer, but it's not like it would be any more expensive for Nissan just to use smooth hoses there. Most vacuum cleaner hoses are corrugated, got to be a reason.
