Helloooooo! Since my 150mph run i decided i need a high flow air filter.
Anyone suggest what would be the best one to get?

That depends, if you're wanting to use it on cooler days or just to race/track your car then I'd go with a BMS dual cone intake. If it's warm where you live or if you're going to be driving your car for long distances where your engine gets really warm then just go with a drop in filter BMC/BMS seem to be the most popular brands on the forum.
