For the Synapse Engineering R35 GTR Cold Air Intake Kit, we have designed a set of tapered venturi inserts to maintain the signaling that the factory ECU needs in order to have a smooth operating range. This kit is already included with the Synapse GTR Intake kit, but for those that need an extra set, we can sell them seperately.
This product was added to our catalog on Saturday 13 October, 2012.
