Ok, be very cautious with the filters that come from the import tuner market. Most of them are for show and actually kill your performance and ability to breathe. Don't tell the ricers. We think it'* funny that they don't know this.
Regardless of the outcome of the water test, I'd strongly encourage you to ditch the filter and buy a known-brand proven performer that actually shows the performance specifications, has a good reputation in the performance market, and posts more information on their website than just the multitude of different colors available.
