BMW F10 - 550 K&N intake filters!
I met up with Black tonight and purchased some custom made k&N intake filters.
1- the quality is great!
2- simple replacement of the original. Takes less then 5 minutes.
3- instant increase In throttle response and a slight increase in turbo spool/sound.
4- I feel a slight increase in power delivery. feels smoother and quicker.
5- price $450. Worth every penny!
6- I will dyno soon to see if there are any differences .
GROUP BUY IS A MUST!
