Single Plenum Kits

Spectre’s 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 filter away from the hot air, your engine can utilize the cooler, denser air closer to the ground or outside of the engine compartment, which helps to increase performance over an open element on top of the engine. If hood clearance is an issue, look into using one of our low profile or ultra low profile DTM plenum kits.
