Features: Dual stage foam: Two different pore sizes create more trapping area for even the smallest dust particles Flame laminated foam: Both “stages” are not glued, but heat sealed to provide maximum air flow Reticulated foam: Increases dirt stopping surface area and increase foam strength Strongest glue seams will withstand harsh solvents and gas (although we can’t understand why you’d want to use them). Pull as hard as you can, foam will rip before the glued seam will Light color foam easier to spot where the filter oil has covered and where it has not OEM size for more dirt stopping capability Handmade Every square inch of each filter is and inspected for quality One year warranty Made in the USA, not a cheap Chinese throw away Fitment: 2007 Gas Gas EC 200 2007 Gas Gas EC 300 2007 Gas-Gas EC 250 2007 Gas-Gas Ec 450 Fsr 2007 Gas-Gas MC 450 FSR 2007 Gas-Gas SM 450FSR 2008 Gas Gas EC 200 2008 Gas Gas EC 250 2008 Gas Gas SM 450FSR 2008 Gas-Gas EC 300 2008 Gas-Gas Ec 450 Fsr 2009 Gas Gas EC 250 2009 Gas-Gas EC 200 2009 Gas-Gas EC 300 2009 Gas-Gas Ec 450 Fsr 2009 Gas-Gas Ec 515 2009 Gas-Gas Ec 515 Fsr 2009 Gas-Gas SM 450 2009 Gas-Gas SM 515 2010 Gas Gas EC 250 2010 Gas Gas Ec 450 F 2010 Gas-Gas EC 200 2010 Gas-Gas EC 300 2011 Gas Gas EC 250 2011 Gas Gas XC 250 2011 Gas Gas XC 300 2011 Gas-Gas EC 200 2011 Gas-Gas EC 300 2012 Gas Gas EC 250 2012 Gas Gas Ec 450 F 2012 Gas-Gas EC 300 2012 Gas-Gas XC 200 2012 Gas-Gas XC 250 2012 Gas-Gas XC 300 2013 Gas Gas EC 250 2013 Gas Gas XC 250 2013 Gas-Gas EC 200 2013 Gas-Gas EC 300 2013 Gas-Gas Ec 450 F 2013 Gas-Gas XC 300 2014 Gas-Gas EC 200 2014 Gas-Gas EC 250 2014 Gas-Gas EC 300 2014 Gas-Gas Ec 450 F
