Did anyone see any improvements in the 1/4mile with the air scoops and K&N filters offered by BadBlack550xi and how much did it cost? I was also looking at the intake he offers does anyone have any time slips with this yet? Any other suggestions would be great. Thanks

Me and Arch both are in 11's we both run my filters with scoops. another car identical to mine in mods minus the scoops and filters could only run 12 flat he never got in to 11's and eventually got rid of the car.
I would suggest to get catless downpipes this way you can crank up more boost and get close to 11.9... See where you end up and if you need the filters ill be happy to make them for you.
Arch has the 2014 N63 Tu his record is 11.5 @ 119
