K&N INTAKE FOR 2013+ FOCUS ST
Built for performance this K&N Intake System is a free-flowing mandrel-bent aluminum tube induction system with high quality silver powder finish that is made to last. K
&N intake systems replace your vehicles restrictive factory air filter and air intake housing.
We prefer K&N filter elements due to their reliability, they really do last the life of your vehicle. This saves money in the long run from buying replacement paper air filters every 15K miles. Add in the peace of mind of knowing you have something more substantial than a few layers of paper protecting your investment and the choice is easy.
Be sure to invest in a K&N recharger kit, its a must have when you own a K&N filter. We carry the kits with the aerosol filter oil which really helps to apply a light coat (vs. the squeeze bottles).
Brew City Boost recommends going "easy" on the K&N filter recharging oil (not included) when servicing your air K&N air filter. If its put on too heavy it can build up on your MAF sensor and cause issues. And always remember to only put oil on the correct side of the filter.
