A stainless multi-layer gasket with embossed sealing beads, built to hold a head clamp that a factory gasket was never asked to hold.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy you would fit one.\u003c\/strong\u003e The factory gasket is the usual limit on a tuned 1.6 turbo. Push boost and cylinder pressure past stock and the head lifts fractionally at the hottest cylinder, the fire ring loses its seal and you get coolant loss, a misfire under load, or combustion gas in the cooling system. A multi-layer steel gasket rebuilds the seal with spring-steel beads that follow that movement instead of being crushed by it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e0.024 in is a thin gasket, and that is deliberate.\u003c\/strong\u003e It is about the thickness of a standard gasket rather than a raising shim, so it does not drop your compression ratio. That makes it the right choice when you are rebuilding a healthy engine for more boost. If you are running forged pistons and want compression taken out of the engine, you want a thicker gasket instead — ask us and we will quote one.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFitment.\u003c\/strong\u003e Cometic publish this gasket for the 1.6 litre Gamma II turbo (G4FJ). On the cars we sell that is the Veloster Turbo and Veloster Turbo R-Spec, the Elantra GT Sport, and the Kia Forte Koup SX and Forte5 SX. \u003cstrong\u003eTell us your year and we will confirm it against Cometic's own application list before it ships\u003c\/strong\u003e — the 1.6 appears in several states of tune and not all of them are this engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis is a bored-block gasket size.\u003c\/strong\u003e 78 mm is the gasket bore, slightly larger than a standard 77 mm cylinder, which is normal and gives the fire ring room to seal. It suits a standard bore and a light overbore alike.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHead bolts are not reusable.\u003c\/strong\u003e The factory head bolts are torque-to-yield: they stretch permanently when first tightened and must not be re-used on a rebuild. Budget for a new bolt set, or head studs, with this gasket. We would rather tell you now than have the job come apart later.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetails:\u003c\/strong\u003e one cylinder head gasket; Cometic HP multi-layer stainless steel; 78 mm bore; 0.024 in (0.61 mm) compressed thickness; Cometic's application data lists it as a three-layer gasket with a valve-pocketed bore shape.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSurface finish matters more than the gasket.\u003c\/strong\u003e A multi-layer steel gasket needs a smoother deck and head face than a composite one. If the head is coming off anyway, have both faces checked for flatness and finish while it is apart.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAvailability:\u003c\/strong\u003e ON ORDER at our distributor as of 6 November 2026.
