Product Description

HKS offers a stopper head gasket kit for the FA20 engine in two compression ratios, slightly lower and higher than stock. For naturally aspirated builds, HKS suggests their 12.6 compression gasket set, and boosted builds should opt for the slightly lower 12.4 compression. 

This HKS head gasket set features a Stopper ring in the middle layer to promote a great seal point as illustrated in the attached image.
