    Edward ★★★★★

    I swapped out the old cap on my '95 Civic and this one sealed perfectly from the first turn, holding a steady 1.3 bar even after a hard canyon run. The billet aluminum construction feels much more solid than the plastic OEM piece.

    Ella U. ★★★★★

    Swapped out the old cap and this one sealed perfectly on my stock radiator with zero leaks. The 1.3 bar rating gives me peace of mind during hard pulls without blowing hoses.

    Julian ★★★★★

    The pressure rating is exactly what my turbo setup needed, and the spring mechanism feels high quality when installing it. This cap sealed perfectly on my stock radiator and hasn't leaked a drop since I put it on.
