Product Details

The Cometic C4984-030 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Mazda BP-4W Turbo and BP-Z3 engines. This precision gasket features an 85mm bore diameter and .030" (0.76mm) compressed thickness, making it ideal for turbocharged applications and performance builds requiring enhanced sealing capabilities.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 85mm bore diameter designed for Mazda BP-series engines
  • .030" compressed gasket thickness for optimal compression ratio tuning
  • Engineered for high-boost turbo applications and performance builds
  • Resists combustion chamber pressures and extreme temperatures
  • Compatible with BP-4W Turbo and BP-Z3 engine variants

Cometic MLS head gaskets utilize multiple layers of stainless steel with specialized coatings to provide exceptional sealing under extreme cylinder pressures. The .030" thickness allows engine builders to fine-tune compression ratios for forced induction setups, making this gasket a popular choice for Mazda Miata, Protege, and other BP-powered performance builds. Each gasket is manufactured to exacting tolerances to ensure proper sealing and long-term reliability in demanding applications.

Good to go!

Easy website. Also made a quick call to sales to ensure part availability. Very friendly and quick!

Best auto parts buying experience I have had in recent memory! Maybe just luck that I lived within 200 miles of where the parts originated, but the delivery was extremely fast!! And the price beat everyone else I could find, and I searched extensively.

Quick and simple

I am well satisfied with my order

Nice and easy

Good products at a good price as well as a simple transaction

Fast shipment, but overall part quality was slightly sub par. The fittament of the lights was not very good and took more effort than what I thought it should be.
