The Rugged Radios 4C IMSA Helmet Kit with Speakers (HK-IFSP) is a wired in-helmet communication kit for sports-car road racing that uses a 4-conductor IMSA plug and includes helmet speakers plus a dynamic noise-cancelling mic. It is used in series such as LMP2, GT3, GT4 and TCR and installs into most helmets.

Compatibility

Connects to a standard IMSA car harness using the 4-conductor (4C) plug. This version has built-in helmet speakers instead of an earbud jack, so no earbuds are required. Does not fit a 3-conductor NASCAR harness. The mic boom and cable junction block install with hot glue or the Rugged Quick Mount (HK-QM, sold separately); it is not a plug-in-only install.
