Product Details

The Cometic C4172-059 is a high-performance cylinder head gasket engineered specifically for Toyota 18R-G engines. This precision-manufactured gasket features a 92mm bore diameter and .059" (1.5mm) compressed thickness, providing reliable sealing for modified and high-performance applications.

Key Specifications:

  • Bore Diameter: 92mm (3.622")
  • Compressed Thickness: .059" (1.5mm)
  • Material: CFM-20 (Cometic's aramid fiber composite)
  • Application: Toyota 18R-G engines
  • MLS-style construction for superior sealing

Cometic's CFM-20 material combines aramid fibers with a fluoroelastomer binder, creating a gasket that excels in high-heat, high-compression applications. The material compresses evenly and maintains its integrity under extreme cylinder pressures, making it ideal for turbocharged, supercharged, or high-compression naturally aspirated builds. This gasket provides excellent conformability to cylinder head and block surfaces while resisting combustion gas leakage, coolant seepage, and oil migration.

Performance Benefits:

  • Superior sealing performance compared to OEM composite gaskets
  • Excellent temperature resistance and thermal stability
  • Maintains torque retention without retorquing
  • Resists gasoline, alcohol, and oil-based fuels
  • Ideal for engines with aftermarket cylinder heads or decked blocks

This gasket is designed for performance enthusiasts building Toyota 18R-G engines for racing, street performance, or restoration projects requiring upgraded sealing reliability.

Very detailed list of part fitment. Radiator fits and functions very well. BUT, and this may be no fault of Autoplicity, I received the radiator w/holes punched in the box and some of the cooling fins bent. It wasn't bad enough to warrant a return, thoug

product just as described, received in 3 days

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

Great prices will shop here again.

Excellent on-line merchant with outstanding customer service and the best prices on equipment and shipping. Highly reccomended!

Good prices and easy ordering process (order #18003). The only issue that I had was after placing the order, completing the entire process, I received three emails stating that "We noticed that you started checking out on our site, but didn't quite finish the process". After calling customer service, they ensured me that the order was complete. Since then, I receive the same email(3 emails at a time) on a daily basis. Just a little annoying, but easy enough to delete.
