Thanks for sharing bro! 
8.9hp is alot of gain just from a filter mod. But of course the bigger the engine displacement or a super/turbo-charged engine will benefit most of it.
Like in the link, they use a supra (300 to 400hp??) and got 13 to 14hp. Tats alot man...
Do you know which filter is on Des M3? |
The standar kit comes with K&N airfilter unless he changed to something else.
