C15 AcertIPD piston 3466615 was developed for industrial C15 Acert applications. Some customers requested that this piston be packaged with components applicable to on-highway truck applications. As a result, IPD developed the following kit: KIF6615/12/CS kit As a precaution,this kit contains cylinder liner 1599778CSWS (.001” oversized ID) crevice seal liner(based on 1599778, which was introduced by the OE and IPD to help prevent piston scuffing in high load applications). Piston 3466615 is a 16:1 compression ratio piston that is not specified by the OE for on-highway usage(i.e., lower compression than the similar on-highway piston), and thus is not a direct replacement option for these applications.CAUTION IPD does not endorse the usage of these kits as higher performance “modifications”. The extent of these modifications is an unknown, some may be identified by the engines’ ECM, some not. Any modifications may affect other engine components, service life, emissions standards, and so on.Accordingly, tampering or altering an engine design via modifications that deviate from OE manufacturer operating specifications for the intended application is in violation of IPD’s written warranty. As a result, IPD only offers these kits on a “No Warranty” basis
