The concept of Cold Air induction is that 1. Cold air is more dense than warm air. 2.The more dense your air is, the more efficiently it will aid combustion. The N2 and O2 molecules are moving at a significantly lower rate of speed allowing more O2 to be utilized. Also because the air is more dense, of coarse more pressure exists within the cylinder and forces the piston down with greater force once combustion occurs. Last, in every combustion cycle, not all of the fuel is burned, however, if you can provide more O2 molecules, the fuel is burned more efficiently. In theory, one might even expect a small increase in gas mileage. There are those who say that for every 7 degrees F. the intake air is lowered, 1 bhp is gained.

Oil Catch Tank

FAQ: Why fit an oil catch tank? If your engine breathes back into its induction system it is recirculating oxygen less oil-laden air back into the fuel mix. As the induction system operates at full efficiency on oxygenated air then fitting a catch tank will maybe gain a little horsepower as well as prevent carbon sludge build up in the induction system and throttle body. Simply removing the emissions breather system is not an option on the Probe without other modification as well as being detrimental to the environment, and an MOT fail. For race use cars showing any indications of oil fumes from their breather system will be required to fit a catch tank by the scrutineers.
