K&N Replacement Air Filter
  • Designed to Increase Power
  • Million Mile Limited Warranty
Clarke Hall, Cambridge, Canada
This filter is in my 2011 Jetta. I instantly noticed relief on the engine, way more air flow with little restriction. Best filter on the market and K&N is the only brand that I would suggest to put in your vehicle. Cabin filter, air filter, and oil filter.... K&N all the way . Plus, million mile warranty, can't beat that.
