TOYOTA CELICA, HIACE, HILUX 21R-C, 22R WITH AIR INJECTION STEEL HEADER.
Category: Extractors and headers
The Exhaust Systems Australia TOYOTA-CELICA-HIACE-HILUX-21R-C-22R-WITH-AIR-INJECTION-STEEL-HEADER-GASKET is a steel header gasket listed to fit the Toyota Celica, Hiace and Hilux with the 21R-C and 22R engines fitted with air injection.
A header gasket seals the joint between the cylinder head's exhaust ports and the extractor or manifold flange, holding that seal through constant heat cycling. Steel is used here so it lasts under exhaust temperatures. The "with air injection" callout matters because that engine variant has an extra port arrangement at the head, and the gasket is cut to match it. It's a service and fitment part — its job is to stop exhaust leaks at the head, not to change performance.
It's listed to fit the Celica, Hiace and Hilux running the 21R-C or 22R with air injection. The air-injection detail is the key one — a non-air-injection head has a different port pattern — so confirm your exact engine and head arrangement with the workshop before ordering, since gasket fitment depends on that match.
A header gasket is replaced whenever the extractors or manifold come off these engines — during an extractor fit, a head job, or to cure a blowing leak at the port face. Refitting an old gasket onto a disturbed joint is a common reason a leak returns, so a fresh one is cheap insurance once the manifold is already off.
Oak Flats Muffler Men fits header gaskets like this as part of extractor and manifold work across the Illawarra. We clean the mating faces, check the flange for distortion and torque the fasteners evenly so the seal holds. At a recommended retail of $10.30 it's almost always fitted alongside a larger job. Send your details and we'll confirm it matches your air-injection head.
