You're obviously pretty new to this sort of stuff and that's cool! We all have to learn somewhere!
Google "heat soak" and "Induction kits" you will soon learn the pros and cons of the cone filter v panel filters v proper induction kits/systems.
I personally rate panel filters/closed air box induction kits. Renault invested a lot of money in engineering the car as do most/all car manufacturers and they tend to get these sorts of things right!
If I were you, I would spend some time looking at the pros and cons to modifications that people do and look on here and other forums at what people rate and don't rate. And DONT believe anything in eBay adverts, especially the eBay Super Chips and electric super chargers!! Haha
