Let's reboot this thread and make a deal!
Let's face it the ST200 box is awesome. Mountune has a metal version built by Pro Alloy that sells for $300
I trust Mountune's performance data which is exactly the same as the ST200 box aside from the material it's made from.
The performance data :
the air box has been engineered with features that reduce the delta pressure drop by 2kPa that when coupled with the included high flow air filter, provide a 21% increase in airflow
That sounds good to me!
So here's what I'll do.....the next person to order the ST200 air box will receive a FREE RAMAIR performance air filter.
Simply use the drop down box to select YES to the filter. $0 will be added to the purchase price.
