The thermoset phenolic material keeps the intake charge cooler and more consistent, delivering a denser air\/fuel mixture, sharper throttle response, and reduced vapor lock under hot, demanding conditions.\u003c\/p\u003e\n\u003cp\u003eBeyond temperature control, the spacer increases plenum volume to promote a freer, straighter airflow path. That added volume supports steadier performance during aggressive driving or racing, helping your engine breathe easier from low to high RPM without bogging down or heat soak. The rigid, warp-resistant construction stands up to repeated heat cycles for reliable, mile-after-mile performance.\u003c\/p\u003e\n\u003cp\u003eDesigned with compatibility in mind, it accommodates aftermarket or custom throttle cable\/linkage setups, providing necessary clearance while preserving a solid, gasket-sealed mounting.
