Add dry-carbon finish without giving up the factory insulator
HKS 70026-AT006 replaces the original G16E-GTS engine cover with a 3K twill-weave dry-carbon panel. Its shape is designed to improve airflow organization beneath the hood while allowing the original sound insulation to be transferred.
Key Features
- HKS 70026-AT006 is produced by an autoclave dry-carbon process.
- 3K twill weave and gloss clear finish provide a consistent engine-bay appearance.
- The factory sound insulator transfers to the replacement cover.
- HKS testing found more fresh air passing between the hood and cover at the same vehicle speed.
