Reinforced head gasket, BMW MINI PSA N13B16A N14B16 N18B16 EP6

Here you will find several reinforced head gaskets for the N13B16, N14B16, N18B16 and EP6 engines, from ATHENA and COMETIC, whose technical specification is given below.

The gasket is selected from the drop-down menus just below the price: simply pick the thickness and the type of gasket you want.

Below is the link (click on the image) to the head studs and bolts that fit your N13 / N14 / N18 / EP6 engine:

For reference, here is the technical specification of the original gasket

• Engine bore: 77mm
• Compressed thickness: 0.90mm

Technical specification

• Engine bore: up to 78.5mm
• Compressed thickness available: 0.90mm
• Gasket type: MLS
• Part numbers: 338476R

Designed and made in Italy, the reinforced Athena head gaskets come in two forms:

• MLS: these gaskets are built from several layers of stainless steel, stacked and riveted together. The stainless sheets are laser cut for greater accuracy and given an elastomer surface treatment (NBR or FKM). To seal as tightly as possible, the cylinder outlines and the water and oil passages are embossed. For the most extreme applications, extra reinforcement is added around the cylinders.
• O-ring: these gaskets are made of a steel sheet faced with asbestos-free aramid fibre plus an AISI 304 stainless ring around each cylinder. A silicone bead applied at the critical points (water and oil passages) guarantees maximum sealing of the head gasket. This type of gasket is a must on heavily boosted engines.

Technical specification

• Engine bore: up to 78mm
• Gasket type: MLX
• Compressed thicknesses available: 0.81, 0.91, 1.02, 1.12, 1.22, 1.27, 1.32mm
• Part numbers: C4617, C4617-032, C4617-036, C4617-040, C4617-044, C4617-048, C4617-050, C4617-052

Founded by Bob Gorman in 1989, Cometic is recognised worldwide as a leader in the design and manufacture of reinforced head gaskets. They are made in the United States, as is the whole of the brand's range. Cometic reinforced head gaskets are built from several embossed stainless steel layers held together by rivets. There are three types of Cometic head gasket:

This technology needs less clamping load on the head bolts, which reduces bore distortion and spreads the load more evenly over the whole gasket.

• MLS: the equivalent of the Athena MLS gaskets, these multi-layer gaskets (3 to 5 stainless layers depending on thickness) are embossed around the cylinders and the fluid passages.

• MLX: this gasket shares the same base as the MLS but adds a folded-sheet reinforcement around the cylinders and a special high temperature coating.

• HP: an MLX gasket with one more layer added, in order to reinforce the sealing of the cylinders (see below).
