Standard Height

Spectre’s standard height muscle car single inlet plenum kits are designed to move the air filters away from the top of the engine where under-hood hot air likes to collect. By moving the air filters away from the hot air, your engine can utilize the cooler, denser air closer to the ground or outside of the engine compartment and helping to increase performance over an open element on top of the engine.
