Our CanTune Intake Manifold Upgrade Kit (aka ribbon delete ring) is made in Canada, It was designed to specifically remove the OEM air restrictive ribbon in the intake manifold.   By removing the restricted factory mesh, more air is able to flow into the intake manifold.  Our ribbon delete rings go in place of the factory mesh. Our rings are tapered which do not disrupt the airflow which can cause performance issues and turbulence while protecting the OEM seal from crushing under pressure.  You will require a stainless steel clamp sized for the intake manifold/rubber boot. This will ensure the boot does not pop off during riding.
