Fast delivery service. Was ready for collection with in the next 2 days, even though i live out side the USA. Great filter and have noticed great gain performance after my pro tune. Sounds good on the car while driving and the turbo sounds even better than before. I really appreciate all the effort that went into the engineering behinde this filter. It positioned much further from the engine than my other aftemarket filter and with the air scoop fitting straight into the air box makes this a winner. Highly recommend this airfilter.
Better than Cobb's!
I had the Cobb Big SF intake for a while and it was very inferior to what GrimmSpeed has to offer. The GrimmSpeed air box is a much cleaner setup, hence the "stealthbox" moniker. No fitment issues whatsoever and seems to be louder than Cobb's. Yes you need to get a pro tune with this intake but it would be all worth it in the long run. Don't make the same mistake I did and settled for another brand. Just get this the first time around. Installation was very simple although I did it with ramps to access the bottom (it's much easier than doing it all from above. My car has all sort of GrimmSpeed goodies now: intake, j-pipe, pulley cover, charge pipe, top mount intercooler, and even their Delrin shift knob. Gotta love GrimmSpeed :D
