Fel-Pro MS 90269 is a vehicle-specific fuel injection plenum gasket set engineered to restore a leak-free intake seal on compatible Chevrolet K1500 engines.

When the intake plenum leaks, you can get rough idle, poor performance, and fuel economy drops. This Fel-Pro gasket set replaces worn or damaged intake seals with parts designed to match original equipment dimensions and materials. Fel-Pro’s manufacturing focuses on consistent sealing under the thermal and vibration cycles typical of pickup truck use, giving you a dependable repair component for routine maintenance or engine rebuild projects.
