Great bay but beware of puddles!

I have this air intake on my 2007 S2000 and am very happy with it. In general, the unlimited cold air you can feed the engine, the more power you will produce. This air intake does a great job of drawing in cold air because the filter is right in front of the radiator. The standard intake depends on the air under the hood, which is always much warmer than the outside air. This is an even bigger problem when the car is not moving. A phenomenon known as "thermal soaking” can then occur…

Pros
  • Estimated power increase 7.67hp @ 7300rpm
Cons
  • Weak
