BLOX Racing Ti Retainers for B16A - B18C1-5 (1.6L - 1.8L DOHC VTEC) / H22A 2.2L DOHC VTEC
BLOX Racing Ti Retainers are CNC-machined titanium valve spring retainers designed for B16A B18C1-5 and H22A DOHC VTEC cylinder heads in select Honda Civic Integra and Prelude Acura Integra models. These retainers replace heavy OEM steel units to slash valvetrain reciprocating mass by over 190 grams total and enable revs beyond 9000 RPM without valve float. Track enthusiasts rely on them for sustained durability in high-boost high-RPM competition engines.
