More Info:
The Cometic Multi-Layer Xtreme (or MLX) design includes an extra layer in the gasket and high-temperature polymers and embossments to seal the water passages. The extra layer allows for better combustion sealing, and lower bore distortion.
The MLX Gasket (Multi-Layer-Steel-Stopper) features an extra stopper fold-over layer providing a torque limiting surface that prevents yielding of the combustion seals. High temperature polymer along with embossments provide a micro seal for fluids against the head and block surface.
Shipping Times:
Some special sizes are not always in stock and will be made to order by Cometic. A 5-week wait time can be expected in that case. If you have a deadline, please contact us directly with the part number you need.
