Iceman intakes crack in the winter, due to rapid changes in the temperature of the plastic. I have seen it happen more than once. Stock airboxes and intakes aren't as prone, since the plastic is a softer compound...

Pictures are worth 1000 words. Let's see some proof. Show me one picture of a 'cracked' Iceman and I'll redact an apology.

Iceman FAQ
Q: Will the ICEMAN crack and break like a plastic milk jug?

A. No, the ICEMAN is made of a different type of plastic. Much like the same plastic that your fuse box is made out of, sitting under your hood. In fact the ICEMAN is made from the same type of plastic material as motorcycle tanks, therefore NOS or fuel is not a problem.

Q. How much PSI can the ICEMAN intake system pipe hold?

A. 180,000 PSI

Q. Does ICEMAN come with a limited warranty?

A. Yes it does, it comes with a 5 year limited warranty.

Q. Why does Knight Engineering use plastic for their intakes?

A. Based on scientific reasoning, there are several known factors that impede engine performance.

Among these, operating temperatures and the mass flow of air are the most critical. Overcoming the adverse impact that these factors have in any air-intake design is an engineering challenge.

Knight Engineering met the challenge years ago by originating a three-prong solution that uses plastic as the perfect material to integrate the various problems into a single solution. Below is a quick summary of the qualities found in plastic, and our innovative use of this excellent material to design and produce intake systems superior to anything else on the market.

Three primary reasons:

• 1) Material - We use plastic because it is the lowest conductive material that meets every requirement to solve the problems cited above. For example, compared to thin-wall intake pipes made of aluminum, our intake systems run three times cooler. The importance of supplying cooler air in adequate amounts, relative to engine performance, is discussed in more detail below.
  
  2) Shape - Plastic allows us to have more control over the physical form of our engineered designs than other materials. This means that we can regulate both the volume of intake air (torque) and its velocity (horsepower), to substantially increase performance from bottom-end settings through higher power demands. This increased and instant response can only be achieved by controlling the air intake's length and ID (air chamber), its overall gradual cone shape (velocity tube/air horn), and the smooth route it takes between points (no bottle necks).
  
  Moreover, our process flows to a slick smooth internal surface that eliminates airflow distortions caused by bending and welding metal tubes.
  
  3) Location - Because plastic can be molded to conform to engineered designs, we predetermine the best placement of the filter to draw the coolest air and start from there.
  
  In contrast, metal tubes are made straight and rigid for a multitude of general uses- even intake pipes. However, the actual route that pipes take is driven more by their tight bent limitations, then by design placement. In short, the material dictates the ultimate performance levels, rather than engineering principles. This is a crucial point because, by placing the filter outside the hot engine compartment, operating temperatures are lowered approximately 70-90 degrees F, and more during the hotter summer months. What this means to you is a one percent (1%) power gain for every 10-degree drop in temperature.
  
  4) The resulting increases in fuel economy are simply by-products of engines operating at much higher levels of efficiency.

I assume your friends returned their 'cracked' Iceman intakes to Knight Engineering. I know I wouldn't throw a $200 intake in the trash. Did the replacements 'crack' too???

If they didn't return them, post a picture of one here and I'll eat my words...

...I've never seen anyone who can twist someone else's words around to mean whatever he wants them to mean like you can. Your debate background is apparent.

LOL!!! To prove THIS point, I'll take that as a compliment...
