Does the intake fit without cutting the bonnet ? if so I would take that. Not really interested in the strakes so perhaps work something out with another member ( noodles?)

Phil

hello sorry for my late response.
i sell the side strikes
the intake is for 200 euro plus ship.
u have to cut the bonnet inside the hood
thank you all

O.k Thanks for your reply. I will stay with my K&N fipk as I don’t want to cut the bonnet.

Air is normally drawn in from behind the radiator where it has been heated. The Mugen Hi-Performance Air Intake System draws fresh cool air in from in front of the radiator. High pressure from the grill area also forces air into the duct for a ram air affect.

1. F20C engine achieving a high level of performance is a very delicate engine. Even a small factor may hinder the real power of 250ps. Following is our advice for the optimum use of the engine’s real power.
   1. Always induce the cool outside air.
      Reasons:
      1. Since the density of high temperature air is low, it causes to decrease the power output. For an example, if the induction air temperature rises more 3ºC, there will be a loss of 1% power output.
      2. If the temperature further increases, the engine protection program installed in ECU will activate and limit the engine power output.
      3. Regrettably, the induction port of the standard air box is laid out in such a way that it sucks hot air in the engine room. Therefore, it always induces hot air heated up to above 20ºC to 30ºC.
      Solution:
      Install Mugen air box kit which is designed to induce cool outside air.
2. At Mugen, air box for S2000 cars has been developed for almost a year and half. Many different types of air boxes have been repeatedly tested and the specification was finally decided as a result. Since the development has been carried out for the people who give the first priority to the power performance, there are some unresolved roughness remained for such an area as intake air noise. (It may cause some irritation to ears). Therefore, for those who prefer to have quiet open air driving, we do not recommend the use of this product.
   1. Performance of standard air box and filter.
      High performance filter with a only slight loss of pressure is adopted.
      As a result of measuring the filter’s performance without air box, we found that there was only few horse power (2 to 3 PS) of output loss due to the pressure loss. Overall power loss with the air box was only about 5PS at the top end (in comparison with that of naked racing funnel).
      It is regrettable to note that the standard air box installed in a car induces heated air passing through the radiator into the engine.
      Notes:
      1. As a result of the measurement of the induction air temperature of a car running on the racing circuit and high speed freeways, it was found that heated air which was about 15ºC to 30ºC higher than the ambient air temperature was induced into the engine room.
      2. The density of air becomes about 1% thinner as the temperature rises for about 3ºC and it directly relates to the power down. Inducing heated air of 30ºC will also cause the power down of about 10%.
      3. When the high temperature air is induced over the limit, the engine protection program activates and enter into the power save mode.
   2. Performance of Mugen air box and filter.
      Complete reduction of intake air resistance.
      Since it exceeds even the high performance of a standard filter, the following elements have been adopted.
      1. Adopted a large diameter aluminum funnel of a racing type.
      2. Adopted a racing filter of low pressure loss type.
         
      3. Adopted an air box design of smooth configuration made of carbon fiber.
         Induction of cold air: It is designed to induct outside air from behind the license plate in order to directly induct the outside air to the air box. There will also be a useful effect from the ram pressure air flow which directly hits the induction mouth of the air box if the license plate were removed during the sports running.
         Caution:
         When installing the air box, a portion of the supporting frame underneath the standard bonnet is needed to be cut off. This will require a professional work and therefore please take it to the professional metal working shop. (In case of Mugen aero-bonnet, this work is not required)
