Air Filter Riser Kit

The SPECTRE Air Filter Riser Kit (SPE-4954) is a precision intake modification designed for serious engine builders and performance enthusiasts who demand cleaner, unrestricted airflow to their carburetors and fuel injection systems. If you're upgrading your engine's breathing capacity—whether for a classic hot rod, street machine, or off-road build—this riser kit addresses a fundamental intake design constraint: stock filter housings often create restrictive air paths that rob horsepower and throttle response. This compact component solves that problem by elevating and repositioning your air filter element for optimal flow characteristics.

Engineered from durable materials built to withstand underhood heat and vibration, the SPECTRE Air Filter Riser Kit integrates seamlessly with most carburetor and intake manifold configurations. The riser's lightweight design—weighing only 0.23 lbs—ensures negligible impact on engine bay balance while the compact 2.1 x 7.8 x 6.8 inch footprint allows flexible mounting options in tight engine compartments. By elevating the filter element away from heat sources and engine block radiation, this kit improves filter longevity and maintains cooler intake air temperatures, which directly translates to denser air charge and measurable power gains across the RPM band.

This riser kit is ideal for carbureted engines, naturally aspirated stroker builds, and any application where intake manifold clearance or filter positioning limits airflow efficiency. Mechanics and engine tuners commonly pair air filter risers with larger diameter intake tubes and unrestricted filter elements to unlock the full potential of cylinder head porting and cam upgrades. Installation requires basic hand tools and straightforward bolt-on mounting; verify your specific carburetor mounting pad and intake configuration before purchase to ensure compatibility with your particular engine platform.
