Prompt delivery as usual by MX-5 Parts ( if they can't supply somethingimmediately they send regular updates) , gives a "throatier" sound above 4000rpm. Seems to need less throttle for a particular level of acceleration and gives 1-2 mpg improvement over a standard filter - ( 34-35 mpg compared to 33 with a standard filter on my 1.8 Sport. It may never pay back as you need to buy a cleaning pack every so often, but at least you can rationalise paying for a nice sound !
