Does aftermarket air intakes for 3IS actually produce any gains?
Most of the aftermarket air intakes I see for the 3IS draw air from the engine compartment. This seems counter productive to me. I live in Dubai. So you can imagine how hot it gets. Adding all that heat plus the engine bay heat, it seems to me that the stock setup is more better for performance and reliability. Can anyone verify this? Is investing in an aftermarket air intake like K&N or similar ones worth it?

The K&N comes with a heat shield that blocks the filter from the engine and I believe you'll leave in the bottom section of the stock intake box which brings in fresh air from the outside ... In talks of intakes, here's some things to consider ...
1. Where is the air coming from? Is there a better, less restrictive way, to get clean, cool, fresh air to the engine?
2. What type of filter is the air passing through. For an everyday driver, finding a balance of allowing more airflow but still filtering out contaminants.
3. After the filter, what route does the air take to get into the throttle body? The factory corrugated rubber tube adds turbulence to air which in turn hinders the air flow. Finding a smooth tube; if it's metal, treated with a coating to dissipate the heat or in the case of K&N intakes, plastic which generally doesn't get as hot as a metal tube, is the best option.

The facts say opposite ... Check out the Dyno sheet from K&N. GS350 gained 12.5 HP and 13.6 TQ. Can't really argue with the facts and dyno sheet ...

The only advantage to get an intake is the sound if you are looking for that. However if the car is tuned ( specially turbo charged cars) the intake will make a huge difference due to removing the OEM air box which is restriciting the flow with higher boost.

Any manufacturer that makes a claim is no different than a customer testimonial. Usually its skewed or opinionated in some way or another for marketing reasons. Dyno video with all variables such as temperature, elevation, and other relevant mods done to the car are all factors that must be included before I believe any claim.

Really? With people suing over too much ice in their Starbucks I highly doubt a company like K&N would lie and fake dyno results ... Seems like a good way to throw away millions of dollars and your reputation in the industry for someone calling them out on a $75 dyno pull ... BUT to each their own, believe or don't believe whatever you want ...
