Not for the Toyota GR Yaris \/ GR Corolla (G16E). See the Denstoj G16E kits for those.\u003c\/p\u003e\n\u003cp\u003eThe FA and FB engines have a known weak point. If a valve spring loses pressure, through an over-rev or even in normal driving, a rocker arm can drop out. The cam can then throw it through the tappet cover and dump oil onto the exhaust, and the valve can drop into the cylinder and destroy the piston.\u003c\/p\u003e\n\u003cp\u003eThe Denstoj rocker retainer kit holds the rocker arms in place so this can't happen. It's one of the most important upgrades for any FA\/FB engine, stock or built, and a fraction of the cost of a rebuild. This still applies to the 2022+ GR86 \/ BRZ, and the factory valve spring recall doesn't fix it.\u003c\/p\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDenstoj\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRR-FAFB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSuits\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSubaru FA20 \/ FA24 \/ FB engines\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation:\u003c\/strong\u003e fitted with the camshafts out.
