What is a steel header gasket?
A header gasket seals the joint between the cylinder head exhaust ports and the header or extractor flange, so the exhaust leaves through the pipe rather than leaking at the flange. A steel gasket handles the heat cycling that joint sees on the Astron fours. It's a consumable — fitted fresh whenever the headers come off, not reused.
Will it suit my Mitsubishi Astron?
It's listed to fit the Astron engine family — the 4G51, 4G52 and 4G53 — across 1.8L, 2.0L, 2.4L and 2.6L. Because the gasket has to match the head's port pattern, send the workshop your engine code and we'll confirm it's the right gasket before you order.
Why a fresh gasket each time?
The Astron is a long-running engine family, and any extractor fit or exhaust refresh on one should go back together with a new flange gasket. A reused steel gasket that's already been crushed tends to leak at the flange and tick under load. On a job that's already apart, fitting a fresh gasket is the sensible call rather than chasing a leak later.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits Mitsubishi exhaust hardware across the Illawarra, checking the flange faces so the new gasket seals first time. At $10.30 AUD RRP it's a small part worth ordering alongside any header work; listed to fit the Astron 4G5-series, confirm your engine with us.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
- Which engines does it cover?
- The Astron 4G51, 4G52 and 4G53 in 1.8L, 2.0L, 2.4L and 2.6L. Confirm your engine code with the workshop.
- Is this a header or just the gasket?
- Just the gasket — the steel flange seal between the head and the headers.
- Should I reuse my old gasket?
- No. Once the headers come off, the gasket should be replaced so the flange seals cleanly.
