Boost Performance with an Injen Replacement Air Filter

Is there really such a thing as a performance air filter?  After all, didn't those early engines just run without filters?  While engines in the old days certainly did run without filters, and today's paved roads are not nearly as dusty as those in times past, an air filter on a modern, fuel injected car is a must.  And, as engineering and technology have continued to advance, we know a lot more about the conditions that an air filter has to operate under.  This means that today's air filters can play a part in improving engine performance.

Important factors that affect air flow include the temperature of the air, the volume of air that is delivered to the intake manifold, and the turbulence in the air as it comes through the filter.  The Injen replacement filter tackles all of these factors to deliver superior filtration and performance.  This Injen replacement air filter is constructed from four layers of cotton gauze for maximum flow and filtration.  A built-in velocity stack reduces turbulence, delivering high volumes of free-flowing air.  The urethane top isolates heat, keeping the air from being warmed as it comes into the filter.

The Injen replacement filter delivers maximum performance when complemented with Injen's line-up of air intake kits. Don't have an Injen cold air intake system?  You can still use the filter-just measure your current filter and order the same sized replacement.  These Injen replacement filters come pre-oiled and ready to use. It is washable, and so can be cleaned and re-used rather than just thrown away.  Injen covers this filter with a lifetime warranty for years and years of great service.  Upgrade your engine's performance with an Injen air filter today!
