DryFlow Pre-Filters are manufactured from a durable micro-screen material and pretreated with a proprietary hydrophobic process designed to prevent splashes of water or mud from saturating your DryFlow air filter. DryFlow Pre-filters also stop small dirt particles; yet add little restriction.
Give your vehicle the power boost it needs with these AEM Dryflow Synthetic Filters. These filters offer 99.4% filtration as small as 1 micron without the use of oil while also helping to increase you gas mileage. Oil-free filters are MAF friendly as they will not pollute your MAF wire with oil, causing your car to run poorly.
