Engineered for Bosch throttle body applications, these precision-cut gaskets deliver reliable sealing in both OEM and performance-oriented builds. Constructed from 1/8" thick Delrin material, they offer superior chemical resistance and dimensional stability across temperature cycles. The material's inherent thermal properties create effective isolation between the throttle body and intake manifold, reducing heat soak that can compromise fuel atomization and throttle response. Delrin's low friction characteristics also minimize gasket creep under clamping loads, ensuring consistent sealing pressure over extended use. Ideal for street and track applications where repeatability and durability matter.
