Product Details

The Cometic C4128-066 is a high-performance multi-layer steel (MLS) cylinder head gasket specifically engineered for Jaguar XK6 engines displacing 4.2 liters, covering model years 1973-1992. This precision gasket features a .066-inch compressed thickness and is designed for a 3.670-inch bore diameter, ensuring optimal sealing and combustion chamber integrity.

Key Specifications:

  • Multi-layer steel (MLS) construction for superior sealing and durability
  • Compressed thickness: .066 inches (1.68mm)
  • Bore diameter: 3.670 inches
  • Application-specific design for Jaguar 4.2L XK6 engines (1973-1992)
  • Provides excellent resistance to combustion pressure and thermal cycling

Cometic's MLS head gaskets utilize multiple layers of stainless steel with advanced coating technologies to create a superior seal between the cylinder head and engine block. The embossed active sealing areas around combustion chambers, coolant passages, and oil return ports ensure reliable performance even under high-stress conditions. This gasket is ideal for both stock rebuilds and performance applications where reliable head sealing is critical.

I recently ordered 2 Borla Dual Round Intercooled Tips from Autoplicity.com for one reason and reason only...their prices can not be beat! No where else online can anyone match them! <br>

great pricing and fast shipping

My initial review was 1 star because I ordered a Thule rooftop cargo box, but cancelled the order after Autoplicity called me about collecting extra money to ship the item after their website did not charge me enough for shipping. After my initial review Autoplicity offered to ship the item totally free since the issue was a flaw in their website. This was unexpected, above and beyond in my opinion. I have yet to receive the item but commend Autoplicity's customer service

Easy site to navigate and nice prices! Installation was ad avertised-took a little lo0ndre than an hour before I was on the road!

I was looking to buy a gale banks header for my jeep. I came across this site th eir price was nearly $100 cheaper than any one else. Fast shipping too. Thank you.

Did not receive a confirmation email when I placed the order so I was unsure if if the order had gone through properly. Part shipped the day after I ordered it. I received three confirmation emails at the that time for some reason. Overall I would say the experience ordering from Autoplicity was excellent and inspired confidence.

Product arrived fast and as described. The best price I found online. Packing was excellent, highly recommend Autoplicity.

Great Company. I needed a part quickly and for the right price. They had the best price on the internet, and made sure it got to me in two days before I went away on my road trip. I spoke to a representative that was very helpful. I highly recommend Autoplicity! Thanks!!!

Great site! Just what I wanted!
