So I've been looking around for the D Sport air filter as I hear it gives a nice sound and better response and came across this: http://global.rakuten.com/en/store/wattsu/item/1371678/?s-id=borderless_browsehist_en At under £40 I thought this was on. Know of any cheaper? Worth doing? Then a few other items caught my eye There is the D Sport pipe kit: http://global.rakuten.com/en/store/wattsu/item/17113-e080/?s-id=borderless_browsehist_en The D Sport intercooler: http://global.rakuten.com/en/store/wattsu/item/1375462/?s-id=borderless_browsehist_en And finally the D Sport radiator cap: http://global.rakuten.com/en/store/wattsu/item/1371661/?s-id=borderless_browsehist_en Are any of these worth getting from your experiences? Does anyone know of anywhere cheaper? Hope this helps others who might also be interested.
