The initiall reason for bringing out an induction kit was demand for one by you lot out there, so you would have induction roar with a gain in performance. The gain in performance is due to a freear flowing air filter and the roar from not having a completely sealed box. Granted the hole at the top will draw in some hot air, but no where near as much as some of the other (open) induction kits on the market. We saw that there is a need to get more cold air to the filter and to this end have made a scoop to fit in front of the passanger wheel which sits just below the bumper line and scoops cold air up to the ind housing. One problem you will always have with this is that the car needs to be moving to scoop the air. I personally think that a better option would be to remove the passanger side fog lamp and feed cold air from there. I have looked at the possibilities of the little blank to the side of the lamp but if anyone cares to take of there bumper to see where abouts you can feed any decent sized air pipe is welcome to have a look. The reason we have not yet made a fog lamp scoop is demand, a lot of people do not want to remove the lamp because it upsets the look of the car I say what do you want a faster car or one that looks symetrical. YOU TELL ME IS THERE A DEMAND?
As far as a fully sealed air box goes fitting a free flow performance air filter will also gain power and coupled with some sort of better cold air feed will more than likely give power gains similar to the ind kit. One problem with this against an open kit is that the air feed needs to be higher than under the bumper, should you drive through a flood. We decided that we would not make a fully sealed kit as the Renault version works and the Ramair filter we supply as a direct replacement is £41.13 inc vat retail. So there we have it Ive just blown away the induction kit thery.
Ultimately its the old saying. You pay your money you take your choise.
